Now THIS is an episode that is actually USEFUL!!! I have noticed the weird storage capacities of SSD storage before I saw this video, but I had never heard that term "Overprovisioning" before. Keep making videos like this that are truly useful for educational purposes and your subscriber count will explode!
Linus I wish you went more into Gigabytes vs Gibibytes, since it has a lot more impact on advertised storage vs actual storage than you talked about. My SSD has an advertised capacity of 480GB. According to Windows 10 however, it has a capacity of 446GB. Now it's time to take the advertised storage to the GB to GiB converter. 480GB is equal to 447GiB. I'll do this on another drive as well. My 3TB HDD, according to Windows 10, has a capacity of 2.72TB. Again, throw it into the converter. And the result is that 3TB is equal to 2.72TiB. Just a note I thought I should add, since Linus never went into detail about this in the video. Edit: I did round off my results.
Its also worth pointing out that, most (or all) computer storage manufacturers uses a base 10 system (1 GB = 1,000,000,000 bytes), but computers always uses base 2 system, so 1 GB (Or the Linux users might see the OS mentioned it as GiB: Gi"Bi"Bytes) is actually 1,073,741,824 Bytes. So, for every 1 GB the hard drive advertised, you'll lose around 73 megabytes when the computer addresses it (without addition in formatting overhead, file systems and such)
Not all OSes show gibibytes. So, to be sure, you can just check the byte count, then divide that by 10⁹ to get size in gigabytes (10¹² for terabytes, 10¹⁵ for petabytes, etc).
fun story: my office computer was running out of space with only 100GBs available on it's HDD. I was going to upgrade it a bigger SSD, so I looked into drive management work out some partitions in preparation to the new drive, it had 900 GIGABYTES OF UNALLOCATED SPACE! that computer from 15 years ago had a 1 TERABYTE HARD DRIVE IN IT WITH MOST OF IT JUST NOT ALLOCATED!
Anyone else feel my pain over GB vs. GiB (or MB vs. MiB, etc). When I learned all this 30 years ago, there was no KiB, it was just KB, and 1 kilobyte = 1024 bytes because 1 byte = 8 bits. Damn Apple.
I miss the defrag coloured blocks that used to display the amount of defragmentation being corrected. I used to watch them till the early hours of the morning.
I care about my personal space. Let's step up here, and everybody get stepped up, and let's get some stepped up PERSONAL SPACE UP IN THIS PLACE! Here we go. We get a 1) personal space. 2) personal space. 3) stay out of my personal space 4) keep away from my personal space 5) get out of that personal space 6) stay away from my personal space 7) keep away from that personal space 8) personal space 9) personal space. You know, I take personal space pretty seriously. This message brought to you by Tunnel Bear. They care about personal space.
Another reason why the SSD is best used as your OS drive since you won't be overwriting, or moving your OS (generally). You can use one for more volatile storage, but you won't get as much longevity.
0:46 partially right, but you have to realise that Windows uses the 1024 byte system, and the manufacturers state the unformatted capacity of their drives, because it isn't known what the OS the SSD is going to be used on
The first SSD I got was an 80 gb intel ssd for 200 dollars 10 years ago. It had a read speed of 250 mb/s and a write speed of 95 mb/s (sequential), but far higher random read/writes than hard drives. I just got a 1000 gb ssd for 145 bucks which has a read speed of 560 mb/s and a write speed of 525 mb/s. That's a decrease in cost per gb by a factor of around 17. Incredible stuff. My build lasted 10 years before I replaced the motherboard and CPU, and it still ran fine. This is why I suggest building your own so you can replace parts as needed.
Thanks Linus. That was really informative. I knew that there was a reason for the weird partitioning numbers, but now I know why. Love the format. You guys should have Jon do more Tech Quickies: maybe one a week? Loved the Dyson Sphere, cause it was on my favorite topics; science, technology, and fiction!
I was agonizing over this when I got reminded of it months after I bought my ssd and is now almost full. Fortunately it was in one of those odd sizes, 240 GB so it turns out I don't need to do manual overprovisioning at all.
It's also true for USB data sticks. There are factory utilities that can modify the provisioning and you can increase the life and decrease the usable size or vice versa.
SSD's write things into what are called pages, which are then organized into blocks, which are then integrated into larger cubes, which of course are part of the larger "binder" organization structure, which are then super imposed over the matrix stack.
Is everyone seriously disliking? Is it just because of the intro? This video is seriously an informative video. Even though I already know about it this is definitely a good video.
I have got mine to 300 megabytes free of 16 gigabytes (6.04 used by android nougat 7.0.0) and it's fine but i would NOT recommend it because updates for apps will not download from the Google play store (butihavetheazpenstore)
i don't think the first issue is formatting overhead. it's the manufacturers scamming that 10^9 Bytes = 1 GB, instead of the proper 2^30 Bytes = 1 GB. you can easily check it yourself
For 1, why there're unconventional capacities - this is likely down to the individual chips making up the SSD. Say they're manufacturered in 60GB chips. Take two, that's 120gb, take four and you have your 480gb. Eight, there's your 960gb. (Though looking into it, they probably are just nipping away at 64/128GB chips) And for point 2, showing up in lower capacities when reported by your OS, this is mostly Windows now, and it's due to the difference in definitions of GB. Windows still uses the 1024 bytes to the kb, whereas manufacturers and other operating systems use 1000. If you do a quick conversion - (1000/1024)³ x 512(GB) = 476.8(GB). I know that Seagate specifically add this extra 7.37% difference for the provision such that it really is a 512GB drive, but really any amount can be added by the manufacturer that's invisible on the OS-level for the sake of ssd shuffling as it were. So for these, I find the images and topics on this Techquickie a little misleading. (Especially since #2 will also be evident in conventional mechanical hard-drives, which don't use overprovisioning)
Teacher: ok class can anyone tell us what 1,073,741,824 mega bytes translates too? Kid 1: thats a gigabyte!! Random kid in the corner that never talks: unh uh that theres a darn G I B I B Y T E
Here's the reason why many people are complaining about the intro: It's too long for the format of the video. "Ughh, but it's literally a few seconds long" - Yea, but the video is literally a few minutes long... If I were watching a podcast (~1:30h) I wouldn't care if you were plugging your stuff for 5 minutes because, guess what, I probably have the time to 'waste', where as on a fast-paced informative video that is 4 minutes I don't... Not to mention how repetitive it will get if you bingewatch a few of them one after each other... (Seriously, listen to the intro a couple of times and you'll see what I mean) "But you're just entitled!" - Maybe I am a little bit... but something like this gets *really* annoying for someone like me who binges videos and I don't think that it's that big of a thing to request that they make it an outro (which if it were 4seconds instead of 7, people wouldn't have time to click off of by the way) or at least shorten it so it's a bit better... Also, for those who are like "It doesn't matter to me" or "I don't care", you do realize that there are other people besides you in the world, right? Just because it doesn't affect you doesn't mean it also doesn't affect me. "Ahh, you milenials!" - ...
they actually saw a growth in subs since last week around when the intro was added, so yeah I do think it is beneficial. More people are going to see the intro than an outro after a sponsor and its fact, so it is the best place to put it and it clearly has been working. According to Linus 55% of watchers weren't even subscribed which is a big percentage.
+Rasv I wasn't arguing about the effectiveness of the intro, but about how annoying it is... If they would put it immediately after the video is over and before the sponsors, I don't think that people would have the time to click away without at least hearing part of the message... That way it will be pretty much as effective while being way less annoying for frequent viewers...
Great Techquickie. I'd like an episode in the future on how you can turn off the part of the video that asks you to sub if you already subbed. I'm kinda shocked RUclips hasn't provided a solution for that already. Like when you go to a channel you're not subbed to, the channel can play you a welcome video but once you are subbed, that welcome video doesn't play. Why can't we have that same idea applied to every video. Where you have a subscribe/press the bell clip that gets attached or prefixed to any video where you haven't indeed subscribed/belled but that clip goes away once you are. Another step for RUclipsrs but one that I think the audience as a whole would really appreciate.
Harddrive manufactures report the capacity is GB (Giga bytes), which is 1.000.000.000 bytes. While the operating system reports the capacity in GiB, gibibytes, which are 1.073.741.824 bytes.
For some reason the SSD in my computer actually did the opposite of overprovisioning by adding .11 GB of space. My SSD was advertised to be 512 GB, but it is actually 512.11 GB.
This is why I bought eleven 2 TB SSDs, used 1 TB for over-provisioning, and threw them into a RAIDZ-3 (raid 7) array for a useable volume of 7.55 TB. It'll last forever... Yes, I'm kidding. Six drives in three striped mirrors is nearly as fast, half the cost, and hot-swappable with minimal recovery time. For home, I use Samsung Magician's Power Saving Mode (PSM) on my 1 TB SSD formatted under NTFS. PSM enables both TRIM and Over Provisioning. Very stable, and I use A/B backups.
Another thing to think about is that advertised hard drive and SSD storage numbers are using a 1000mb=1gb formula while the operating system is still using the traditional binary system of 1024mb = 1gb
For all who did not catch the livestream last night: He said they're leaving the intro for a couple months and if it improves sub numbers it stays and if not it goes. Also Jon, if you're reading this nice job with the video m8.
It could be nice if you explained the difference between Gigabyte and Gibibyte. When the industry tried to enter the International System of Units (they finally did it in 1996 or maybe 1999) they found the problem that to keep consistence with units and measures the prefixes "kilo", "mega", "giga", etc. are decimal based units meaning exactly 1000, 1.000.000, 1000.000.000, etc. respectively. Keeping their binary values of 1024, 1.048.576 etc. meaned those prefixes had different values thus would become non standard (which goes against the idea of standarization) so they decided to create new acronyms like "KiB", "MiB" etc. meaning (K)ilo B(i)nary (B)yte, (M)ega B(i)nary (B)yte...And it's the reason when you buy a 500 GB (Gigabytes) Windows says you have just 465 Gigabytes total space. Because Microsoft are a bunch of idiots and refuse to accept standards. The right form Windows should explain it is "465 GiB (Gibybytes or giga binary bytes) total space"
So when you buy a 500GB disk it means it has 465 GiB. In HDD and SSD in my own experience they always keep the decimal (Gigabyte) but when you buy RAM most of the times they use the GB acronym when they should use the GiB one (because it really has the announced GibiBytes). Some brands of discs (CD,DVD,Bluray...) use one or the other acronym and in my experience they use it well (for example 4.7 GB DVD equals 4.5GiB, TDK normally uses the GiB form).
I got a question... if I run 2 operating systems from one ssd does that reduce the lifespam of the drive ? if there's always one partition of data not being used at the back end of the drive with files not seeing use? does the controller treat it differently ?
Huh. I noticed the weird capacities when I went SSD-shopping, but I never thought about it that much. This is good to know. Incidentally, I subscribed to Techquickie because this channel was very informative when I was building my first PC a couple years ago, and because I just like learning random stuff. I enjoy how the topics are presented. If you need to get more subscribers for this channel in order to justify working on it, I'm fine with the intro.
It makes me laugh that most of these people are probably in the middle of taking a shit yet they are complaining that the seven seconds of the intro completely ruins their day but they will comment on it over and over again. Just be happy that they make these awesome videos for free and enjoy them without blowing an o-ring lol
Finite read-write cycles is the reason I want to stick with magnetic hard drives at least for OS storage as long as Western Digital and/or Seagate will make them.
@2randomcrap3: The crappy part is that they (ie. hard-drive manufacturers) are intentionally making them crappier (secretly changing ALL-of-them to Shingled-Magnetic-Recording method, for example) to move-over everyone (by force) to SSDs :-(
Ok, I saw the stream about the intro and with that in mind I would suggest shortening the subscribe bit, I find the enable notifications bit drags the intro out and is a bit clunky. Maybe just "If you like this please subscribe" and just visually suggest the use of the bell icon.
You also loose space when they use chunks of say triple layer flash as if it were double or single layer flash as a write buffer cause its much faster for writes.
Leaving free space on Windows with TRIM enabled will do the same, partitioning just prevents you from using the space in the first place. But if you know better, having space in a pinch even temporarily is better than blocking it off forever.
Hi Linus - great video, but I feel a primary point was missed as far as drive size is concerned. It can be confusing so here goes - all drives actually have sizes allocated by powers of "1000" megabytes - so when the drive lists itself at 5 Gigs - it's actually referring to a total space of 5000 megabytes. But WINDOWS reads the drive at 1024 megabytes per (Gibibyte), not 1000 - so inherently, all drives will automatically read as a 2.4% smaller size - simply due to the way Windows does the mathematics specifically. So there are the things you did mention in the video, but don't forget the math - that's important too.
SSDs have a limited write lifetime..... Now think about all those MacBooks with the SSD Soldered on the Motherboard that have to be sent back to the factory for replacement.... Thats right, Apple doesn't repair most of the time, they tell you to upgrade.
> "... advertized to hold the more typical amount of data like 512 GB, why does your computer tell you the actual capasity is far lower?" > Proceeds to then show a hard drive with 512 GB of capasity, identified by the operating system as having 512 GB of capasity. The real question should have been "why does Windows tell 512,108,785,664 bytes = 476 GB?". It's due to Windows using a stupid convention where 1024 bytes = 1 kB, 1024 kB = 1 MB, 1024 MB = 1 GB and so on, which only makes sense for ram these days. It has absolutely nothing to do with overprovisoning in SSD's and it's really confusing since you can't differentiatie these power of 1024 based prefixes from the proper power of 1000 based SI prefixes.
So if you're a frequent Techquickie viewer, you've probably noticed by now that we added a intro to our videos as a simple upgrade that will usually make your viewers get annoyed and more, but we keep it in for whatever reason.
I mean, you could just very easily press the right arrow button, which skips most of the intro. But like most people are annoyed, because they dont want to sit through 7 seconds of blah blah blah reminding them of something they already did. The only argument that there is is the fact that there might be more people being aware of the buttons existance. Now, I dont have the data Linus and his staff members have. Maybe this intro does something after all, who knows.
marco_rennmaus Maybe the intro should get changed to "If you're new to Techquickie, click the subscribe button..." and continue on with the rest of the intro.
marco_rennmausb Linus did a livestream on this yesterday he explained that about 60~70% of viewers on techquickie are not subscribed. This compared to 30~40% for the other channels
Now this is a real Techquickie!!!
PS thanks for the upload
The Master Agreed!
The rest are all a cringy mess
thumbnail looks from the 80's, haven't watched the vid but suck my grapes. Edit: wait......... add a solid state driver?........????????????????????
The Master i know! but they still didnt get rid of the cringy intro
Now THIS is an episode that is actually USEFUL!!! I have noticed the weird storage capacities of SSD storage before I saw this video, but I had never heard that term "Overprovisioning" before.
Keep making videos like this that are truly useful for educational purposes and your subscriber count will explode!
1:15 Linus predicted the overprovisionning of toilet paper :)
Lots of empty unpartitioned space at supermarkets and convenience stores -- exactly as intended and designed, nice.
*When you haven't watched techquickie yet*
"Thanks for watching techquickie"
WAT
Rattacko full verse please ?
He said , during the previous month , we recommended sdd in your pc . We thanks you for watching techquicki .
Rattacko Don't watch news too much often . Because they only shows part of it .
I'm talking about the intro
It was just so quick that you missed it
When my wife starts to sing I always go out and do some garden work so our neighbors can see there's no domestic violence going on.
Brutal
Huh?
Just some auditory violence, nothing to see here!
2017 to 2020, Linus aged 10 years, though his voice stayed the same.
Linus I wish you went more into Gigabytes vs Gibibytes, since it has a lot more impact on advertised storage vs actual storage than you talked about.
My SSD has an advertised capacity of 480GB. According to Windows 10 however, it has a capacity of 446GB. Now it's time to take the advertised storage to the GB to GiB converter. 480GB is equal to 447GiB.
I'll do this on another drive as well. My 3TB HDD, according to Windows 10, has a capacity of 2.72TB. Again, throw it into the converter. And the result is that 3TB is equal to 2.72TiB.
Just a note I thought I should add, since Linus never went into detail about this in the video.
Edit: I did round off my results.
Its also worth pointing out that, most (or all) computer storage manufacturers uses a base 10 system (1 GB = 1,000,000,000 bytes), but computers always uses base 2 system, so 1 GB (Or the Linux users might see the OS mentioned it as GiB: Gi"Bi"Bytes) is actually 1,073,741,824 Bytes.
So, for every 1 GB the hard drive advertised, you'll lose around 73 megabytes when the computer addresses it (without addition in formatting overhead, file systems and such)
Not all OSes show gibibytes. So, to be sure, you can just check the byte count, then divide that by 10⁹ to get size in gigabytes (10¹² for terabytes, 10¹⁵ for petabytes, etc).
fun story: my office computer was running out of space with only 100GBs available on it's HDD. I was going to upgrade it a bigger SSD, so I looked into drive management work out some partitions in preparation to the new drive, it had 900 GIGABYTES OF UNALLOCATED SPACE! that computer from 15 years ago had a 1 TERABYTE HARD DRIVE IN IT WITH MOST OF IT JUST NOT ALLOCATED!
It wasn't a fun story.
Wtf
I'd like to see a video from you explaining the difference between Garbage Collection and TRIM, and how important each is.
TechQuickie's intro poisoned our water supply, burned our crops and delivered a plague upon unto our houses.

damn, so it is possible to overclock an ssd huh
technology has come too far
It was also possible to overclock HDDs back in the day, but it was kinda hardcore.
I love how you look to the right of the screen when you say something confusing
Great video, I cannot believe that You guys were able to squeeze in so much information into just 4:53 (including advert).
0:46 partially right, but you have to realise that Windows uses the 1024 byte system, and the manufacturers state the unformatted capacity of their drives, because it isn't known what the OS the SSD is going to be used on

I looked the MAC Book Air which has an SSD. Are you saying that at some point in time the SSD will no longer have space to write/save data?
Is everyone seriously disliking? Is it just because of the intro?
This video is seriously an informative video. Even though I already know about it this is definitely a good video.
The intro really needs some getting used to. Great video though
That's an awesome feature!! Found out now in magician sw for my samsung evo ssd. SSDs should do that automatically!
Does this apply to eMMC and UFS ?
Do I need to keep 6 GB of my 64 GB phone empty to keep it good ?
Or can I have 99% filled and no worries ?
I have got mine to 300 megabytes free of 16 gigabytes (6.04 used by android nougat 7.0.0) and it's fine but i would NOT recommend it because updates for apps will not download from the Google play store (butihavetheazpenstore)

When I head The intro I went to hit skip ad and realized it wasn’t an ad :(
Seems like an interesting feature ... There's quite some guides on SSD performance, and few mention this function.

Samsung removed overprovisioning in Samsung Magician 5.0 indicating, that they no longer deem it to be necessary.
Harddrive manufactures report the capacity is GB (Giga bytes), which is 1.000.000.000 bytes. While the operating system reports the capacity in GiB, gibibytes, which are 1.073.741.824 bytes.
If over provisioning is a thing why not put more nand chips on the SSD to account for the lost space?
ALWAYS EXPLAINING THESE TOPICS SO CLEARLY!!!!!!!!!! THANK YOU!!!!!!!!!!
So, what happens if you later on decide to add a partition to the unused space?
The ad goes by quickly so it's not bad, second of all it's like less than 5 seconds so chill xD
For some reason the SSD in my computer actually did the opposite of overprovisioning by adding .11 GB of space. My SSD was advertised to be 512 GB, but it is actually 512.11 GB.

This is why I bought eleven 2 TB SSDs, used 1 TB for over-provisioning, and threw them into a RAIDZ-3 (raid 7) array for a useable volume of 7.55 TB. It'll last forever... Yes, I'm kidding. Six drives in three striped mirrors is nearly as fast, half the cost, and hot-swappable with minimal recovery time.
For home, I use Samsung Magician's Power Saving Mode (PSM) on my 1 TB SSD formatted under NTFS. PSM enables both TRIM and Over Provisioning. Very stable, and I use A/B backups.
which is better for long term storage and archiving? SSD or HDD? if you write files into SSD once will it last for ever?
Seeing how almost all NES cartridges still works fine. I would go for a SSD.
that was I was thinking
This explains why my 1050 (1tb) gb m.2 drive only has 990 of usable space.
wheres the CC?
After watching this video. I have started loving my old Hdd
Another thing to think about is that advertised hard drive and SSD storage numbers are using a 1000mb=1gb formula while the operating system is still using the traditional binary system of 1024mb = 1gb
For all who did not catch the livestream last night: He said they're leaving the intro for a couple months and if it improves sub numbers it stays and if not it goes. Also Jon, if you're reading this nice job with the video m8.
It could be nice if you explained the difference between Gigabyte and Gibibyte. When the industry tried to enter the International System of Units (they finally did it in 1996 or maybe 1999) they found the problem that to keep consistence with units and measures the prefixes "kilo", "mega", "giga", etc. are decimal based units meaning exactly 1000, 1.000.000, 1000.000.000, etc. respectively. Keeping their binary values of 1024, 1.048.576 etc. meaned those prefixes had different values thus would become non standard (which goes against the idea of standarization) so they decided to create new acronyms like "KiB", "MiB" etc. meaning (K)ilo B(i)nary (B)yte, (M)ega B(i)nary (B)yte...And it's the reason when you buy a 500 GB (Gigabytes) Windows says you have just 465 Gigabytes total space. Because Microsoft are a bunch of idiots and refuse to accept standards. The right form Windows should explain it is "465 GiB (Gibybytes or giga binary bytes) total space"
So when you buy a 500GB disk it means it has 465 GiB. In HDD and SSD in my own experience they always keep the decimal (Gigabyte) but when you buy RAM most of the times they use the GB acronym when they should use the GiB one (because it really has the announced GibiBytes). Some brands of discs (CD,DVD,Bluray...) use one or the other acronym and in my experience they use it well (for example 4.7 GB DVD equals 4.5GiB, TDK normally uses the GiB form).
I got a question... if I run 2 operating systems from one ssd does that reduce the lifespam of the drive ? if there's always one partition of data not being used at the back end of the drive with files not seeing use? does the controller treat it differently ?
Best transition in awhile.
I was a bit sceptical at first, but the new Intro is growing on me.
Well what if you just keep some space open? Same thing right?
Huh. I noticed the weird capacities when I went SSD-shopping, but I never thought about it that much. This is good to know.
Incidentally, I subscribed to Techquickie because this channel was very informative when I was building my first PC a couple years ago, and because I just like learning random stuff. I enjoy how the topics are presented. If you need to get more subscribers for this channel in order to justify working on it, I'm fine with the intro.
To send or not to send an error report?
It's an easy to google but a Techquickie of it would be cool
I like the intro, trust me I do. But the problem everyone has with it is that it should be at the end as an outro
Do a video about the The Life Reckoning Checksum Error
It makes me laugh that most of these people are probably in the middle of taking a shit yet they are complaining that the seven seconds of the intro completely ruins their day but they will comment on it over and over again. Just be happy that they make these awesome videos for free and enjoy them without blowing an o-ring lol
tfw the Techquickie channel has far better content than the actual LinusTechTips channel
I learned something today, yay! :)
Finite read-write cycles is the reason I want to stick with magnetic hard drives at least for OS storage as long as Western Digital and/or Seagate will make them.
@2randomcrap3:
The crappy part is that they (ie. hard-drive manufacturers) are intentionally making them crappier (secretly changing ALL-of-them to Shingled-Magnetic-Recording method, for example) to move-over everyone (by force) to SSDs :-(
Linus is this also true for M.2 SSDS as well? Or just normal SSD l size and SATA format?
I don't think that leaving an unallocated partition will make SSDs see it as an over provisioning space. Where is the source of that info?
Great video
I liked this video just for the explanation of GiB. Also as someone who works in the storage industry this video is well done.
Ok, I saw the stream about the intro and with that in mind I would suggest shortening the subscribe bit, I find the enable notifications bit drags the intro out and is a bit clunky. Maybe just "If you like this please subscribe" and just visually suggest the use of the bell icon.
Good video. This was some valuable information and I was wondering what was going on.
I didn't like the intro until I realised that Dennis made it and now I like it lol
You also loose space when they use chunks of say triple layer flash as if it were double or single layer flash as a write buffer cause its much faster for writes.
Excellent explanation! Congrats!
Love these vids! Never knew!
Leaving free space on Windows with TRIM enabled will do the same, partitioning just prevents you from using the space in the first place. But if you know better, having space in a pinch even temporarily is better than blocking it off forever.
Always wondered what this options was in Samsung Magician.
Hi Linus - great video, but I feel a primary point was missed as far as drive size is concerned. It can be confusing so here goes - all drives actually have sizes allocated by powers of "1000" megabytes - so when the drive lists itself at 5 Gigs - it's actually referring to a total space of 5000 megabytes. But WINDOWS reads the drive at 1024 megabytes per (Gibibyte), not 1000 - so inherently, all drives will automatically read as a 2.4% smaller size - simply due to the way Windows does the mathematics specifically. So there are the things you did mention in the video, but don't forget the math - that's important too.
So basically you have to let some space free in order to make work the SSD.
_Ironic._
Considering that SSD only relies on RAM-like operation unlike HDD, that is not that surprising.
i have a question : to increase memory, is it better to have two 8gb ddr( stick, dont know the word...) or one 16gb ?
2 sticks will work a bit faster.
99.9% Of comments are people complaining about the people bitching about the intro
.1% are actual complaints about the intro
Cool info thanks! You should do a TechQuickie episode on VPNs and how they work!
Blakehx well
ruclips.net/video/DhYeqgufYss/видео.html you are two years too late I'm afraid
Hahaha, my bad... And thanks! 😜
new stylist for linus?
SSDs have a limited write lifetime..... Now think about all those MacBooks with the SSD Soldered on the Motherboard that have to be sent back to the factory for replacement.... Thats right, Apple doesn't repair most of the time, they tell you to upgrade.
> "... advertized to hold the more typical amount of data like 512 GB, why does your computer tell you the actual capasity is far lower?"
> Proceeds to then show a hard drive with 512 GB of capasity, identified by the operating system as having 512 GB of capasity.
The real question should have been "why does Windows tell 512,108,785,664 bytes = 476 GB?". It's due to Windows using a stupid convention where 1024 bytes = 1 kB, 1024 kB = 1 MB, 1024 MB = 1 GB and so on, which only makes sense for ram these days. It has absolutely nothing to do with overprovisoning in SSD's and it's really confusing since you can't differentiatie these power of 1024 based prefixes from the proper power of 1000 based SI prefixes.
So if you're a frequent Techquickie viewer, you've probably noticed by now that we added a intro to our videos as a simple upgrade that will usually make your viewers get annoyed and more, but we keep it in for whatever reason.
I mean, you could just very easily press the right arrow button, which skips most of the intro. But like most people are annoyed, because they dont want to sit through 7 seconds of blah blah blah reminding them of something they already did.
The only argument that there is is the fact that there might be more people being aware of the buttons existance. Now, I dont have the data Linus and his staff members have. Maybe this intro does something after all, who knows.
marco_rennmaus he did a livestream about it. And they actually do have some very good reasons for it. I think the video is still up from last night
marco_rennmaus Maybe the intro should get changed to "If you're new to Techquickie, click the subscribe button..." and continue on with the rest of the intro.
Newport31311 Sadly, it's not...
marco_rennmausb Linus did a livestream on this yesterday he explained that about 60~70% of viewers on techquickie are not subscribed. This compared to 30~40% for the other channels
Great Explanation......
Also binary Gigabytes.
Also I am sticking to Mechanical Drives. Also I still use CDs and DVDs. I won’t buy computers without optical drives
I find my Samsung 860 Evo msata increases its temperature by 10 degrees after I overprovision it... Is it normal?
Really helpful guys........ Just increased my knowledge on SSD.
#tech quicke
Keep up the good work linus
The comment section is filled of
99% "The intro sucks"
1% "Do a video on ..."
Listen to your subs and move that intro to the end
Konrad Godel He had a livestream where he said they weren't going to get rid of it. If you can't handle a 7 second wait, that's your problem
They keep doing bullshit no one wants or doesn't care about.
Press the L key to skip it
its 7 seconds if you dont like it leave
Konrad Godel - Yes, you're right, he should listen, because 95% of his subscribers don't give a shit about a frickin'
