RAID 5 & RAID 10 Tutorial & Explanation (NCIX Tech Tips #79)

Today Linus does a follow up to our RAID0 and RAID1 video and he covers some of the more complicated types of RAID, including the ones that are more optimized for dedicated RAID cards.

[@qopiqq3629]

This linus guy should start his own youtube channel, he's good.

[@aherprasad]

Naaaah, he'd definitely fail...

[@mackiebuena1952]

seriously? hahaha

[@jamescabarr2921]

Is this Linus son all grown up? Way to succeed his father's footsteps!

[@incubus_the_man]

@@jamescabarr2921 baby Linus has come a long way.

[@thomashammel524]

Wow, blast from the past! So much has changed including Linus!

[@MSum5]

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.

[@dbiswas123]

Excellent presentation , with a sense of passion. Thank you so much !!

[@samhill4275]

Super helpful! Much better than the diagrams I was looking at, thanks!

[@robdeezle]

That was very helpful couple of videos, I've always heard of raid 0 being used but never knew what it meant... Thanks :)

[@beees3499]

Can someone please hold that whiteboard for him??

[@kevinkeane6682]

Good, clear explanation of what can be a confusing topic.

[@dezmond9152]

I watched the first and needed more baby linus so now i'm here

[@placeholder7054]

LOL baby Linus

[@Osteele]

Great presentation. Glad I stumbled upon your channel. Thank you for sharing.

[@aschris87]

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...

[@FrankZambaras]

OMG! Clicked on this and was surprised by the young Linus. You've come a long way, son!

[@FfejerooShore]

Thanks, Linus. Very informative video!

[@takealready]

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

[@RavindraSingh-fl5sc]

Super Tutorial...Its very useful for us. Thanks Dear.

[@QuadroNVS]

thanks alot ...i didn't fully understand raid untill i watched this video

[@brooklynzoo81]

Great video and informative. Keep up the good work.

[@akamike102]

good info answered a lot for me

[@rgs822]

Amazing intro! Thank you

[@RetiredRhetoricalWarhorse]

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.

[@Sleepersunfire]

great explanation dude

[@CruelQuertos]

Thanks for the help linus

[@jeff-TessAD2022]

Outstanding presentation! Thanks..subscribed! JD

[@modo203]

Dude you're great! :) so cool for a geek! keep up! best from NY

[@radwiimp]

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...

[@-Wreckanize-]

@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)

[@endlrls]

Thanks for the Up.

[@doubleatheman]

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.

[@TheNiggiboy]

thanks for the instructions!

[@blackcoffee730]

Great video!

[@MarcWeavers]

still good info just over 10 years later :)

[@bodyguardxxxl]

Cool the RAID controller is blinking! I want one!!

[@mrosebro]

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)

[@ncbenr]

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.

[@greatwavefan397]

This feels like a cool college lecture.

[@nobodypersonsomeone]

Awesome vid

[@TheDaULTIMATEdude]

need to watch this again LOL for the info to sink in;D

[@markchristou3352]

great video

[@BrutalTurtle]

welcome to ncix tech tips

[@alphafort]

nice clear explanation :)

[@KanchanaRandika]

Thanks for the nice explanation... (Y)

[@deathrow989]

@Borridd Yep! works fine

[@mikeymike11206]

excellent info... one question, do you still need to use identical drives when building RAID's?

[@sergeialeinikov1046]

Thank you!

[@AstroGamerSteve]

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.

[@mastermindzh]

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

[@silver2screen]

This guy is a boss!

[@2DeCipher]

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.

[@AKKSV]

Nice info

[@Ceadderman]

Hmmm, missed this RAID coverage. Wish I'dve seen it before building my RAID0 drive. If you want to be safe though I would just get a +3rd drive(depending on your RAID config) and use it for back up duty as long as it's the same size as your RAID config. Problem solved. You have a faster setup than a single drive and you have the safety of running in RAID1 w/o the loss in performance. BOOYAH!

[@theAboodNet]

What brand and model for RAID Controller used in his setup?

[@estesb23]

All these years later, this is what my computer science teacher has us use to learn how to create RAID

[@HetDerwel]

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.

[@soccersport]

Great this helped me alot.

[@POPCORN454545]

Linus would you recommend raid 5 for a gaming desktop machine? Or like you said just a file server or whatever, cause im gonna get a 4th HDD in a little bit, and i'm wondering if i can use raid 5 instead of raid 10, cause i get more space that way. I don't loose 2tb's i only loose 1tb....pls respond :D.

[@GoldSrc_]

I always keep the 0's and 1's on paper as my back up.

[@francistheodorecatte]

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.

[@TyneGibbs12]

The little red scrolling bar on the back of the adaptek raid controller. Have a look on KZbin for Knight Rider (he has a scrolling red light on the front of him).

[@Omellykim]

o linus you are my hero

[@babyfaceassassin21]

i never had raid before but i want to have my pc configure it that way. i just want to ask how will you going to know which hard drive is failing (in case its going to fail) in a raid setup???

[@ETphonehomek]

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.

[@bullishbear277]

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

[@VirendraBG]

Which raid I should use if I want highest "seq write speed"? How much space I will get if I have 4 SSDs of 1 TB each? What will be tolerance for it? 1 or 2 drives? Please help me to understand.

[@Its__Cole]

Will a RAID 5 setup be compromised if the hard drives get re plugged into different ports?

[@Dawgmeatt]

What type of Raid set up does Linus use with those like 8 or so SSD on his personal rig?

[@dexterdevil1]

good job.

[@cwose]

Would it be a good idea to have two low-storage ssd drives in raid 0 for rapid booting, then some hdd in raid 10 for mass storage? Thanks.

[@AhmedFromKSA]

just wondering if you had 2 raid cards can you raid the drives form the first one with the other

[@JosephLee0312]

i learnt a lot from you thx :D

[@KnowledgePerformance7]

nice call there

[@omgodzilla10]

@Ri1seAgainst Where? On Newegg, they're around $150+. There's one for $113, but it's only 5400rpm and 3gb/s.

[@TWBrit]

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?

[@GEEKinLyfe]

I say next you should do a video explaining a good star craft 2 setup headset, keyboard, mice, (maybe even game pad's).

[@quietk]

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.

[@Drogos79]

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

[@Browmandude]

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

[@gr8108]

I like that type of "open pc case". Where can I get one? Or, how it is called?

[@lenso010]

how can i setup first raid1 for c drive and second raid1 for d drive. basically 2 raid setting on same computer? do i need special raid card(s) for that ?

[@3tjrunner3]

I have that mobo, i have 2 SSDs in RAID 0, you probably could also do a RAID 1, but not sure on that

[@JACKxELITE]

This guys a dork, he'll never get anywhere in life. ❤️😂😂

[@jacobmcr858]

I think that you should mention that the given drives in the RAID 5/6 examples are 1TB apiece.

[@TheMastercheif1598]

So is it reccommended to have a raid controller for a arid 10, and how much usable memory would i have if i had 4x2tb drives in a raid 10?

[@snuggleseal]

what are the differences (PROS+CONS) between RAID 10, and RAID 01 ????

[@XriverdogX]

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

[@gunngin3586]

is it possible to make raid 0 between two 1tb drives and a raid 1 between the raid 0 drives and a 2tb drive?

[@kingnick6260]

Which multiverse have I entered now

[@greatelectronics2035]

How many drives can fail if i have 6 drives in a raid 5 array?

[@Pyro37976]

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.

[@riloh58]

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.

[@techtutorials326]

Can I get your opinion? What's better an SSD and and HHD. Or two HHD at raid 0? The HHD would be at 7200 rpm 1tb. thanks.

[@christaylorchristaylor]

How do I get into the bios. My machine says keyboard failure after the dell screen saying f1 bios f2 boot options . If I was building a pc and I got this message is the motherboard damned because I can't Change the drive to cd or from cd to hard drive. Finally do you need any extra hardware

[@kennykiller911]

can you have two ssd's on raid 0 and back up the data with a mechanical drive using raid 1

[@TheFearOfLegends]

should i use RAID 10 for youtube video storage?

[@sambarrett3059]

Which is faster then ssd's in raid ten or ssd's in raid five or six with a controller

[@tbaldwin102]

So can I set up three 300gb HDs in raid 0 and have a 1tb HD set up as the raid 1 for all disks??

[@jerbear197]

Any videos on rebuilding a disk

[@DenisVinny]

Nice video. In terms of physical implementation, I have no doubts. I want to know from you if I can setup a RAID 10 in a Windows 2008 Server with the required 4 Hard Disks only using Disk Management. I know we can setup RAID 0, 1 and 5 only on Disk Management, but did not see anything related to RAID 10. Can u pls tell me?
