Just remember that if your hard drive gets dirty, just take it apart and scrub the disc vigorously with household cleaning products. Buff with paper towels to dry it all and voila your drive is squeeky clean. I've done this many times but by some strange coincidence the drives all failed right after cleaning. So make sure to clean your drives often!
I had WD SN750 500gb, weird long boot up upon fresh Windows 10 and check hours of usage: it was 90 hours long. Later became unusable and had to contact the seller. Refunded and got a new one without issues.
Every time I have to explain this stuff to people I can only marvel at the engineering involved. HDDs are truly a wonder of precision and development. They catch a lot of flak these days for their slowness, but for a mechanical option in a digital environment, they're about as fast as physics allows them to be, and very reliable for something that is mechanical with nanometer level precision.
A very good video! However, it's already old technology. The only remaining advantage of harddrives is their price. There are already SSD drives available with 100TB capacity. Technology is always fascinating, though! Thanks for the video!
Yes...and only people like Linus can afford them or bigger hardcore businesses. It's already a hefty price tag for PC enthusiasts who store over 10 TB of stuff to smack down around 500 + bucks for a single 15TB to 18 TB hdd.
Excellent explanation on the technology! Back in 2015 I said goodbye to HDDs for good. Since then only SSDs, today 500GB NVMe for Windows & everything and 1TB SATA for archive and games. I regret nothing. The loading time that I saved by going all SSD is invaluable. PS: Snows read your Twitter DMs ;)
I love hard drives especially since I use OpenZFS 2.0 and I keep using all my HDDs everywhere: - 2003 Back-up server, a Pentium 4 HT (2 x IDE 3.5" 250 + 320GB and 2 x SATA 2.5" 320 + 320GB) used for ~1 hour/week. - 2011 Laptop i5-2520M (2TB, new), currently used for 95% as backup server 2. - 2019 Desktop Ryzen 3 2200G (500GB + 1TB; ~8 power-on years; stand-by after 5 minutes). The HDDs are partitioned as 2 x 500GB in Raid-0 cached by 95GB SSD partition and a 500GB partition at the end of 1TB cached by 33GB SSD partition. The HDDs are used for less than 6 hours/week. For the daily stuff I have a 512GB nvme-SSD (3200/2300MB/s). This week I like to try a Proxmox server on ZFS. I want to reuse a 2008 Phenom II X4 B97. I like to try 2 ancient IBM SCSI HDDs (10,000 rpm; 18 + 36GB) + 80GB SATA HDD. Also configured with 2 x 18GB in Raid-0 and 18 + 80GB in LVM if possible. Now I only have a 160GB sata HDD (2.5"; 35MB/s) free, that Dell sold to me in 2008 in a Windows Vista laptop :( :( I keep it as USB2 or USB3 drive. All other drives I have kept, are below 13GB and all are IDE.
Really good explanation, learned a few new things from this video! Side note I love seeing advancements in PC tech even when it comes to simple things like storage, I was amazed when seagate finally made multi actuator drives which I wondered for years why they didn't before. I also thought they could do the same for disk readers so consoles can play games off of large capacity blurays (which are pretty cheap now) instead of waiting forever to download games to play them.. but I fear companies would rather sell expensive external hard drives vs keeping convenience.
Here's your daily anxiety attack: my 250GB is still perfectly healthy. I'm cloning it to my newer drive one of these days though. No need to keep tempting fates for so long, this trooper of a drive is on its 16th year of service. They don't make em like that anymore. (Seagate Barracuda) Also, great, great episode. Love the detail and thorough research, and you glide over the information like that write head. Writing right into my brain :D
Adding the "blooper" with the cut and beep was excellent! Subtle background music to add the ambiance, and not as a second vocal track in volume levels, is very much appreciated and noticed.
Anyone else have anxiety when he's waving the drives around in the air? Like they could drop any moment. Good video btw. My first drive was 750GB in 2008 i believe. Then 3TB in 2012 or something and now 14TB a few years back. Also 500GB and 2TB + 2TB PCIe 4.0 SSD's too. I think im good in terms of capacity and speed for the forseeable future.
HDD is no longer viable. That 16TB HDD you have there, how long before you can fill that up? The SATA interface is very slow for multi TB drives. If time is important to you, the only solution right now is the SSD.
@@maynnemillares The answer for that is RAID. More capacity and faster speeds combined. You as a user would see them in a GUI as one big drive, when in reality they are multiple drives linked together. There are multiple RAID levels tho. Depends on your need of performance and redundancy. We use RAID 5 in our data center at work. We can monitor them, swap out one drive as soon as it fails and continue on without a problem
I still use and buy large capacity HDD (the CMR type) as secondary drive and file storage. It still fits my needs, I still have the "patience" to "wait" for it . . . . .
There are a options to make more memory, using math and to the power to system and re coding how the head both reads and writes it, combining multiples of 1s and multiple 0s or making larger dives doubling the thickness of the drives total thickness . Good comparison is like twin of 3080 ND comparing it to the thickness of a aorus 3080 xtreme. Another idea is using sensors and light. Which would work with the first idea.
Very interesting video, learned a lot, now I wonder if it's possible to make HDDs faster and more competitive to SSDs so they wouldn't fall behind them in the future
Actually SSD's go way beyond HDD capacity already. The biggest HDD is 20TB tho the biggest in retail is 18TB. The biggest SSD atleast in the 2,5" form factor is 30TB already. Atleast in the retail tho i believe there are some specialized 100TB solutions too. The biggest M.2 form factor SSD is currenbtly 8TB and the biggest PCIe 4.0 M.2 is 4TB. Obviously the biggest problem with such huge SSD's is their price vs HDD. But in terms of capacity they have already exceeded HDD's.
This was incredibly informative and educational. How on Earth do we build the technology to build this technology? It just breaks my head thinking about how we have mechanical parts making things on the microscopic level. Crazy.
I remember calling a friend the moment 2GB (2.5 GB? Not quite sure...) drives became available. I think it was WD that was first, but it's so long ago that I really don't remember. Thing is these drives were absolutely humongous compared to the 500MB drives we were using. Now these were not the first HDD's we had, those were 10 or 20 MB. Yes, MB. I built a external disk chassis and installed a 40MB full height 5¼" Micropolis SCSI drive to use with my Amiga 500. Now for those who wonder a full height 5¼" drive is as thick as two regular DVD drives. The drive alone was heavy. With the chassis it weighed probably twice as much as the A500 it was attached to. But back to the story. I worked for a computer company and immediately ordered one of these new huge drives for each of us even before I had talked to my friend. At the time we felt there would be many years before we would need more disk space, so it probably wasn't a year before I added another even larger drive...
@@videoviewer2008 I have worked with some pretty old stuff such as magnetic core memory and the weird acoustic memory used by a terminal that had what looked like a spiral torsion spring in the base with a "kicker" at one end and a microphone at the other. I think it stored about 800 chars encoded with seven bits, possibly six or even five if it only used capital letters. It was a long time ago and I can't remember the details. As for HDD's I've seen a lot of interesting designs and formfactors. While in school I got to tour a data center where they were replacing all of their old drives that used disk packs with these fantastic new HDD's that stored almost a GB in a single unit. It was a cabinet a bit more than a meter high and almost as wide. When you opened it up you saw a round metal enclosure that surrounded the actual disks which almost filled the cabinet. I estimate the disks to have been about 80 cm to a meter in diameter. The disk was driven by a belt drive, the motor in the bottom of the chassis. This was state of the art at the time. Transfer rate, latency, reliability and capacity was way better than the old disk stacks. I think they said a disk pack used by the old drives stored up to 40 MB, but it could just as easily have been anything between 4 and 40. they had something like 80 of these old drives and had long since outgrown the capacity. Before they got the new drives they had to manually swap out disk packs when running less common jobs to have the data needed. All of these old drives were being scrapped, and I got to see some of them doing a three storey dive out of a window and into a dumpster. Pretty heartbreaking to see so much money being thrown away like that. But then it was all so ancient as to be basically worthless. Sorry for rambling on. It was just a deluge of old memories that suddenly got unleashed.
my laptop, which i got in 2018, was one of few that had 2 m.2 slots at the time, and im glad i looked at that but sadly 4tb cap just isnt enough with all the games i have
I use a 1TB SSD for games that I am playing and applications that I am using the most, that require speed. Games I am not playing, mod archives and nonessentials are stored on one of my 2TB, 7200 rpm HDD's. That way my SSD doesn't get slowed down by having to much on it.
HDD is no longer viable. That 16TB HDD he have there, how long before you can fill that up? The SATA interface is very slow for multi TB drives. If time is important to him, the only solution right now is the SSD.
Why not put extra read/write poles on the head to do the shingling in one pass? Forget buffering; read the data just before the overwrite pole passes, and follow it up with another write pole? Can they not cram multiple read and read-write poles on the head? No need to lock up the dingle arm on a single track ring for three revolutions.
Honestly, this seems like a viable option. Given there are 10+ heads. My best guess is that it's an issue with the actuators for the arm. So far, the best they have done is 2 actuators. I'm guessing they are slowing down innovation to 4+ arms to make more money
@@BootSequence I would stagger the poles on each head by one track so that the head remains stationary while rewriting a shingled track/sector. The geometry of the head - that it swipes over the tracks from a slight angle - could be issue as tracks from radically different radius are rewritten. The distance between poles would change slightly depending on the angle of the head relative to the tracks. There is another problem here in shingled recording that the drive briefly contains invalid data. A power loss can corrupt data. I am not sure how big the capacitors are on hard drives but I suspect that there is a limit to how many shingled operations can be in progress while safely assuring that shingling rewrites can be completed in any power loss event.
Hi and I want to add that they could use the forgotten 5.25" HDD format, with 1" height; I want 4 of those with current technology, 256 TB eachwith 9 platters, 2" height, 5400 RPM SMR, I don't give a poop, I want 1 PT in my Desktop PC!
following a nice lawsuit against the SMR (well because the companies tried to sell this as "normal drives") all spec sheets from WD are indicating now if a drive is SMR or CMR Another good indicator is the cache size: a drive with 256mb of cache is very very likely an smr. Although SMR drive are not all bad, they're cheaper and very nice for a backup or a drive to write once and read a lot
@@virtualtools_3021 yes that's exactly the point, you don't use them as a main drive, you use them for something that doesn't need a lot of write, like storing pictures
Probably cause they Cost Lot Less Then SSD and You can Store Huge Amount of Information on them and you DONT Even need SSDs for most things but who knows now a days theres all types of Crazies out there so who knows what they are using HDD for

The professional end doesn't use SATA but SAS (what SCSI evolved into) that can transfer 2.5 gigabytes a second (22.5 gigabits a second). So data centres still use HDs
@@Psy500 I'm not talking about data centers, but rather from the perspective of the end-user. I'm sure the viewers of this video are mostly end-users, who uses a computer for personal computing.
ahh we are already at max 32 K picture data if very much faster and much cheaper real picture live data transfer, so you have to get started alels other is too much garbage and not the same shit about data if you only transfer it but not livethe maximum 32 K adapter is not available yet
Technically hard drives are still good for today, but I wouldn’t recommend it for people building new pc’s in 2021. Unless you’re in a big business or you’re constantly using many terabytes of storage, just get an SSD. Even if it’s a little bit more money the speed difference is worth the extra price 🤷🏻♂️

Ah yes, modern Wearfare
Meanwhile, Axiom Verge 2 (recently released) is only 158 MB :p
cheers
I'm about to buy a new 250 GB hdd for just $19.
Back in the day I saved my porn on floppy disk lol
Evolution of HDD already stops 10 years ago.
Hi Snows
Hello :)!
Probably cause they Cost Lot Less Then SSD and You can Store Huge Amount of Information on them and you DONT Even need SSDs for most things but who knows now a days theres all types of Crazies out there so who knows what they are using HDD for
Great
Hi !😀
Feeding the algorithm with like/sub/bell and comment.
PSA: make a hotkey to help👌
I've had too many HDDs die. 😅 I don't trust them for good data
My 5 years ssd 512 Gb are dead, all data gone 😭. Now i'm use 4 TB HDD not fast but i'm in peacefully
last week i bought a new 4TB of HDD. along with 500GB SSD now i have 1+1+2+4TB hdd.
How many drives in total
4 HDD 8TB Total + 1 500GB SSD for boot.
@@Ajstyle48 is it very noisy in the case?
I'm thinking of getting hard drives since 3 3.5 cages are empty but worried for noise and want system to be quiet as possible
the future of harddrives is in the garbage SSDs will rule supreme !
HDD is for big boii games
"How do we get them to hold more po-" Haha, great joke, but it's _so_ unrealistic! I mean, what sort of depraved porn addict would _possibly_ need more than 18 terabytes of porn‽ I mean, _I_ certainly wouldn't! No, sir! I'm not hoarding even _close_ to that amount!
It's not about the quantity. It's about the quality. 8k my friend. Big files 😂
That's a lot of p..n!
Hi
not bad for, you are canadian right
yes I am
Modern Warefare lol....
HDD is no longer viable. That 16TB HDD you have there, how long before you can fill that up? The SATA interface is very slow for multi TB drives. If time is important to you, the only solution right now is the SSD.
The professional end doesn't use SATA but SAS (what SCSI evolved into) that can transfer 2.5 gigabytes a second (22.5 gigabits a second). So data centres still use HDs
@@Psy500 I'm not talking about data centers, but rather from the perspective of the end-user. I'm sure the viewers of this video are mostly end-users, who uses a computer for personal computing.
ahh we are already at max 32 K picture data if very much faster and much cheaper real picture live data transfer, so you have to get started alels other is too much garbage and not the same shit about data if you only transfer it but not livethe maximum 32 K adapter is not available yet
Technically hard drives are still good for today, but I wouldn’t recommend it for people building new pc’s in 2021. Unless you’re in a big business or you’re constantly using many terabytes of storage, just get an SSD. Even if it’s a little bit more money the speed difference is worth the extra price 🤷🏻♂️
