I started watching Linus about 2 years before he quit NCIX and started his own business and his 1st employee was Luke. At that time I liked Paul's videos at newegg better than Linus NCIX videos.
i love this dude been waitin a long time for a raid guide as good as this one i could watch him for hours talking about hardware. id love to do raid 10 with 4x 500gb samsung spinpoint f3 hard drives as they beat raptors and they are the fastest hard drive out at presant...
Hah, Linus isn't purrfect, Linus isn't purrfect! Ladida! ;) What's described here is not a RAID 10 but a RAID 01. A RAID 10 will first mirror the data and THEN stripe it across two RAID 1 arrays. The difference? Well, if you have four 1TB drives in there and you lose one, you'll only have to rebuild 1 TB of data. If you stripe first, the whole stripe dies and you have to rebuild 2 TB.
quest - find raid array information on my knowledge level explained technically yet also in plain english so it's easy enough to understand. status - completed thank you linux, you have taught me so much yet again! ... stupid bills - keep me from buying toys and setting up ultimate systems... i now want to setup raid 10 for my file server and raid 0 with SSDs for my day to day pc... (if i lose everything on my day to day pc i really dont lose anything)
RAID 10 is like Raid 1+0, but it can also be like 0+1. Depending on your needs, you can mirror then stripe (1+0) or you can stripe then mirror (0+1). Great intro to the topic though.
@Kole208 Raid is just either combining drives into one drive (raid 0) for much faster performance, or using one drive to back up the other drive simultaneously (raid 1), or doing both at the same time with 4 or more drives (raid 10)
A technical correction: RAID 0 does not stripe on a bit by bit level. It does it on a block by block level. Block size is often 16k bytes or higher. Bit level striping is RAID 2, which is almost never used.
Another thing... I would probably advise against using onboard RAID controllers, especially in RAID-5 unless you're using Enterprise or RAID Edition drives. In RAID, if a drive drops out of the array, as they frequently can do using consumer market SATA drives, you'll be required to rebuild the array. With controllers like the Intel/Marvel controllers on most motherboards, for a decent sized array, this can take sometimes up to 3 days! Use a dedicated RAID controller like an Adaptec 6405.
I would use RAID 0, which has the speed of your drives e.g. a 7,200rpm HDD multiplied by the number of drives e.g. three. This would give you transfers speeds equivalent to a 21,600rpm HDD! But make sure to backup regularly with an external hard drive.
Your right those alarms are LOUD! I was working on a client server, I pulled a drive out that was failing. I seriously thought that the fire alarm was going off. Only after I ran out of the server room did I realize that It was the server itself that was making that horrible high pitched alarm sound. It took me several minutes digging in the raid tools to figure out how to turn the alarm off.
@pistolpete2nd I think the way he said it just came out weird. He meant having a RAID 6 with 4 drives doesn't make much sense. 4tb for 2tb, you might as well use a RAID 1 with 2 2TB drives. RAID 6 is more fail-safe but with 4 drive array you'd be paying way too much for it (4 drives + a RAID card). Once you start expanding out to more than 4 drives you start making up the cost of the redundancy (5 x 1TB drives = 3TB)
@herrjonna2007 I can say the same about RAM, I've never had RAM go faulty on me... the fact is, HDD's are moving parts and if you've ever pulled one apart, they are very fragile, bump one while its reading something and the drive goes faulty... not just that but HDD's also store your important data on it! Besides, RAID setups are usually for business computers and servers, they can't afford to lose data from a faulty HDD, the only common RAID setups for home are RAID 0 for gaming
He said that in RAID 10 you can't get your data back if you lose both from the same RAID 0 config. That's not true, the other RAID 0 would be perfectly intact. I think he meant if you lose both of the first half or both of the second half drives from each array.
Dell PERC 5/i is a good bargain RAID controller. does 0/1/10/5, has upgradeable (to 512MB) cache, and 8 SATA II lanes. Uses an LSI controller so you can use LSI's MegaRAID management software.
His videos used to be so useful and delivered so much easy to understand information. Nowaydays, it's too much drama about unboxing, destroying things, or showcasing super powerful cpus, and new technologies.
this was really usefull :D never owned that many drives.. so i couldn't ever try it :P when you said raid 10 = raid 1 and 0 i already got that one lol great review
Depends on how long you have been using computers in general and if you update your hardware often enough to never use a hard drive long enough for it to fail. But I'd consider you lucky. I've lost about 4 or 5 of them to drive failure in 15 years. So one every few years on average. Luckily I've never lost data (or only a small part of it) but been able to replace the drive before a complete melt down.
The little red scrolling bar on the back of the adaptek raid controller. Have a look on RUclips for Knight Rider (he has a scrolling red light on the front of him).
Also, for RAID-5, software RAID is waaay better than chipset RAID, and is comparable to hardware RAID. No idea about Windows, but on Linux best option would be mdadm.
But isn't that RAID 01? In RAID 10 you mirror 2 drives and again 2 drives (and again ...) then stripe those mirrors together. As I understand his explanation he stripes 2 drives and again 2 drives then mirrors them?... (yes I know that video is nearly 8 years old ^^)
@sh00taboy You're wrong dude. Look at the diagram again. He wrote the '0's to the top two drives and the '1's to the bottom two drives. In RAID 10 you can lose one drive containing '0' and one drive containing '1' and the array will still function. Those drives can be on the same side of the mirror or on opposite sides, as long as you have one drive containing each piece of data.
There is always the chance they both can fail at the same time or close enough in time to lose all data. Not only to failure or surge but also to fire or other natural disasters. Thats why its a good idea to have offsite backup like Crashplan or Carbonite.
So in theory two drives should never fail at the same time if you have a surge protector... (I know that they can fail, or maybe not work. Plus usually the company *guarantees* that if your equipment fails it will cover upto X dollars, if your HDD failed you get a new one but your old data is still gone.) So generally wouldn't the raid that covers 2 drive failures not be needed if you have the proper protective equipment
In a RAID 10 array, let's say there are four drives (a, b, c, d). If A and B basically split the data between the two drives, and C and D are mirrors of A and B, let's say both drives A and C fail. Wouldn't you lose all of the data since drive B contains the second half of data for drive A, and D is a mirror of B?
@HostileDonut RAID 0+1 requires minimum 3 disks, RAID 10 requires 4. Other than that RAID 10 has better data protection, especially when you're running more then 4 drives.
@MatthewDavison89 No, raid make better performance, better read and write speeds, but the problem with raid is that if one hdd go's down, (say you have 2 x hdd's in raid0 (best performance) ALL data is lost (coz they are connected as one harddrive to make better performance), but thats why there is raid 5 and raid 10. Safer but slower..
I have a 500GB. Just got 4 more. Could I create a quad stripe and get a program to transfer the data from my HDD to the quad stripe, and keep the original as a backup? In addition I could periodically backup the info off the quad stripe onto the backup HDD to keep it up to date. Or would it be better to just start from scratch and use all 5 drives in a RAID 5? If I did this I would have to get a RAID card, which I have no room for. Would also lose data. The only other option would be RAID 10
Hi, great presentation. I have a query (I hope it makes sense) but surely RAID6 in a 4 disk array provides more security than RAID1 in a 4 disk array (so it does make sense) albeit that storage capacity is the same. Assume you lose 2 drives at the same time (unlucky?), in a RAID1 you would be in trouble if you lost a drive from each side of the mirror and they weren't the same "half". You should still be OK if you lose 2 drives from RAID6. Or am I missing something fundamental? Serious query.
What you are talking about is a UPS (uninterruptible power supply). If you are going to be putting up that kind of money to build a raid you should at least buy a good surge protector they are really cheap compared to what they are protecting. If you can afford it go with a UPS though for about $150 you can get a CyberPower CP1500AVRLCD that's really good for the price and everything in one.
Hey i got a question! I cant seem to get my head around why i would be in trouble if both drives in one of the two raid 0 stripes failed. Wouldnt I then just be left with ONE perfectly good and functional raid 0 array? 3:50
Wait for Raid 10, if you lose both from 1 raid 0 stripe, don't you still have all the data, because you still have a 0 and a 1? Don't you only lose all of your data if the top 2 or the bottom 2 drives fail, so then you would be left with 00 or 11?
I've been reading a lot about RAID arrays and solutions and there is a lot of chatter about different RAID levels and their corresponding speeds but virtually nothing about how I will tangibly feel a speed difference in real life. "Better performance", but better where and how? How do I notice this and not just in a bench?
Hi, bought a U-NAS NSC-800 NAS Server Chassis, it has no PSU, MB or anything. I have a a copy of Win home server etc but what I'm wanting to know (other than recommending a silent 1u psu, MBoards and Drives etc) is; Can I, (with Home Serv) run a 4 disk raid 1 & have stand alone disks as well? and where would the best place be to store complete images of various PC C drives in the server etc? In the video you mentioned use of an SSD - is that something that you can only do on an that card?
Actually there is a big mistake in this video. Raid 10 is not a mirror of stripes but a stripe of mirrors. It's a huge difference. Check out the explanation on wikipedia for example.
If you lost both from one side in RAID 10 wouldn't you still be fine because you'd still have a complete RAID 0 stripe. I think you meant if you lost two of the drive storing the same data. So in terms of the picture if you lost the top two or bottom two then you'd be in trouble.
Your opinion in general on Drobo 5D hooked up with TB, especially with DDR turned on? I am still confused if they are using RAID 6 or some other proprietary technology. Just talked to their CS and according to them you can get DDR even with only 3 drives, which confuses the hack out of me :) thanks for any hints
+Douglas Pomroy yh just gotta remember what raid 0 do and raid 1 do and raid 10 and 01 ill be easy to remember which comes first. 0 = stripes, 1 = mirrors, 10 = mirrors then stripes, 01 = stripes then mirrors if i'm correct.
You should really just go with an SSD for your OS and Programs and have HDDs as backup and mass storage. And if you have the cash buy 2 or more SSDs for the OS and Programs to really kill loading times.
do you need the same hdd's to setup raid 5. i want to use software raid because i was told that if you use hardware raid you need all the same type of hdd's and i cant afford to buy not only a raid card but also buy 2 new hdd's and have 2 perfectly fine hdd's as a waste.
Im from the future. the year is 2058. The Glycions have taken over--- but enough of that. Needed to see some baby Linus! Thumbs up if youre also watching from 2058!
Is RAID 10 hot-swappable when a drive fails and expandable as storage needs grow (or do drives have to be the same size)? Simply put, I want Lightroom and iTunes to have quick access to data stored externally plus expansion options. Historically, my dRobo S has been slow presumably due to the redundancy and HDD overheads. I don’t know if it’s possible to turn my dRobo S into an expandable striped RAID with frequent backups to a dRobo 5N (in RAID 5 or RAID 6 mode) and offsite using Backblaze.
If raid 5 volume with 5 drive (4 data 1 parity), i want using for SQLserver (recommend 64KB for data block size), so how much tripe size (not trip size) i should set for RAID? Thank you.
Could you put SSDs in raid 0, and mirror them on one HDD to get raid 10? If so, would you see the performance of the SSDs, and have the reliability of the HDD?
Could you? Yes, in software. No hardware RAID card will support this... Would you want to? No. Half the time it would be reading from the SSD RAID0, the other half the HDD, which would kill the performance. You're much better off regularly imagining the SSD RAID0 to a HDD for backup.
This linus guy should start his own youtube channel, he's good.
Naaaah, he'd definitely fail...

thank you for educating me. I like radi 10 now. It seems like the best of both worlds.

All these years later, this is what my computer science teacher has us use to learn how to create RAID
I always wondered what the big deal with RAID was. Now I understand! Thinking about picking up a few 1TBs and setting up an array now...
I would've done much better in school if I had Linus as my teacher! :-)

Yeah, I thought I was wrong, If he loses a row (in the figure) he would indeed be in trouble

Losing 1 side of a 1+0 isn't an issue. It is when you lose both sides of each mirror that you are screwed.
There is always the chance they both can fail at the same time or close enough in time to lose all data. Not only to failure or surge but also to fire or other natural disasters. Thats why its a good idea to have offsite backup like Crashplan or Carbonite.
yes, but your drives performance will be limited to the slower one(the hdd) and capacity to the smaller one
Raid 0, he covers that in another video. The problem with doing that is if even one of the drives fail you lose all the data on both drives.
Um, about 4 drive RAID 6 - RAID 1 of pairs of drives would NOT be safer, because, if two drives from same RAID 1 part fail - the whole array fails!
Outstanding presentation!

So in theory two drives should never fail at the same time if you have a surge protector... (I know that they can fail, or maybe not work.

Indeed you would lost your data, he talk about that situation in the video, but that is very unlikely to happen.
Just a point of clarification: What was explained in this video was RAID 0+1 not RAID 10.
@Ri1seAgainst Where? On Newegg, they're around $150+. There's one for $113, but it's only 5400rpm and 3gb/s.
need to watch this again LOL
for the info to sink in;D
good info answered a lot for me
@HostileDonut RAID 0+1 requires minimum 3 disks, RAID 10 requires 4. Other than that RAID 10 has better data protection, especially when you're running more then 4 drives.
I say next you should do a video explaining a good star craft 2 setup
headset, keyboard, mice, (maybe even game pad's).
@MatthewDavison89 No, raid make better performance, better read and write speeds, but the problem with raid is that if one hdd go's down, (say you have 2 x hdd's in raid0 (best performance) ALL data is lost (coz they are connected as one harddrive to make better performance), but thats why there is raid 5 and raid 10.

what are the differences (PROS+CONS) between RAID 10, and RAID 01 ????
What you are talking about is a UPS (uninterruptible power supply). If you are going to be putting up that kind of money to build a raid you should at least buy a good surge protector they are really cheap compared to what they are protecting. If you can afford it go with a UPS though for about $150 you can get a CyberPower CP1500AVRLCD that's really good for the price and everything in one.
Hey i got a question! I cant seem to get my head around why i would be in trouble if both drives in one of the two raid 0 stripes failed. Wouldnt I then just be left with ONE perfectly good and functional raid 0 array? 3:50

excellent info... one question, do you still need to use identical drives when building RAID's?
@theniggyboy no if u do that then it will only be Raid 1 or 0 u need at least 4 drives for raid 10
I always keep the 0's and 1's on paper as my back up.

This guy is a boss!
Or RAID 0, and backup using an external hard drive. Faster than 10 and you don't have all your data in one place.
wow i never knew a dedicated card was better then onboard raid. I always thought a dedicated was only if you needed to have more drives.
Linus....you're wrong about the RAID 10. You CAN lose both drives on the same side; you CAN'T lose both the top drives or both the bottom drives.
Your opinion in general on Drobo 5D hooked up with TB, especially with DDR turned on? I am still confused if they are using RAID 6 or some other proprietary technology. Just talked to their CS and according to them you can get DDR even with only 3 drives, which confuses the hack out of me :) thanks for any hints
Thanks for the help linus
there are infact huge generators right outside most more important serverfacilities
so raid 10 is a raid 1 of raid 0s?
Yes. You get redundancy of RAID 1 and speed of RAID 0. I have seen it referred to as RAID 0+1
+Douglas Pomroy yh just gotta remember what raid 0 do and raid 1 do and raid 10 and 01 ill be easy to remember which comes first. 0 = stripes, 1 = mirrors, 10 = mirrors then stripes, 01 = stripes then mirrors if i'm correct.

What about raid 0 with 3 drives
And also raid 0 with 2 odd spaced drives (one is about half)
I like that type of "open pc case". Where can I get one? Or, how it is called?
Could you put SSDs in raid 0, and mirror them on one HDD to get raid 10? If so, would you see the performance of the SSDs, and have the reliability of the HDD?
Could you? Yes, in software. No hardware RAID card will support this... Would you want to? No. Half the time it would be reading from the SSD RAID0, the other half the HDD, which would kill the performance. You're much better off regularly imagining the SSD RAID0 to a HDD for backup.
Cool but u have to generally buy the same raid hardware to recover ur data if it fails
Shouldn't you still see write and read speed improvements on RAID 5 and 6. Or is because of the controller can't handle writing that fast?
