The nerds and trolls come out in droves to criticize and nitpick. Eli, let me fire back for ya. First of all, look at the description dummies,..."Beginner". If you guys are as smart as you think you are, why are you watching "beginner" videos? For a "beginner", this is a very good video for learning what an array is. Also, this video is 6 years old. Some stuff has changed since then. And where's your instructional videos, smarty pants? Oh, you can dish it out, but you can't take it...because you're afraid of someone crapping on you, the way you just did.
Keep cranking out the vids, Eli. Good stuff.
I have being doing quite a bit of research on tutorial videos, and trust me NO ONE explains things better than Eli. You are a legend!!!!
Up to 12 minutes is basically everything you need to know at a simplistic level about RAID 0, 1, 5 and how they are different from one another. Thanks for sharing Eli.
Eli, These videos are seriously getting me through my Cert IV. Thank you for being so clear!
The Teacher, The Mentor, The Master, The Professional. Eli the Computer Guy! Thank you!
Thank you for great explanation. Well explained. I knew nothing about raid and now it is more clear to me. Give Eli thanks because he takes his time explaining to us who doesn't not know.
For people who said its nothing new because you learned from someone else. Thanks again.
Mind blown by the 2 TB. What a time! Great video, Eli!
No one can convey this to me , in such easy way, its only you. You are awesomme!!!
Great teaching! Inspiring, easy-going and pragmatic. Even after 5y from its recording… Eυχαριστώ (thanks) Eli!
Eli, you are still the Shiznit! I came directly here because I have a son going for a server interview and he needs to really know this as well as networking basics and troubleshooting concepts. Thanks as always for awesome content !!!!
It was never clear until you explained. I would like to say thank you very much and keep going !! God Bless you mate :)
Big thanks for Eli for making this video. Great job!
Love the videos, i'm taking ENE with no actual IT background (nose bleed) and your videos really helps me understand the basics. Thanks! keep it up..
Hi Eli , Thank you so much I'm sure that you receive allot of thank yous but we can't help it , your the best I mean the best teaching when it come to explaining computer tecnology....
Any one can understand and Thank you Mr.Eli for explaining in detal........ Thanks
very Informative. Great Video.
pretty interesting to see his intial videos. He is trying to move his hands present what he is trying to explain. Whereas, now his doesn't care and looks more calm. I love his videos specially the latest ones.
Thanks Eli. Very good intro to RAID. Appreciate you taking the time to do this for all of us!
Still priceless knowledge in 2020. Eli, THANK YOU!
Great video, I knew the basics of RAID but this taught me more than what I thought I knew. SO thank you very much for that!
Eli is the best, i'm learning alot about IT work
as a computer savvy person, this is entertaining. lol...thanks Eli!!!!!!!
I have a knack at PCs and this helps me grow in knowledge of IT work!
first of all thank you very sir. all that you are bringing to us .i have been watching your videos.from last couple of months...and i am highly influenced, we get many new things to learn in great depth..we students need an instructor like you so thank you very much....
Thanks Eli, I never understood this before! Nobody really explained it to me like you have.
Eli you explain things in such an uncomplicated way I m enjoying learning and understanding it. Your helping me through my Microsoft Fundermentals exam.
You are simply the best, I have seen most of your videos I learnt most out of it... You are the best teacher I have ever seen ..it takes a lot... :) Thanks for all your effort.
Wow Eli thank you for that video it was really well done and presented in a simple manner that was easily understandable. I now know what my coworker / IT manager is talking about when he starts talking tech on RAID.
you are one of the best teacher in my whole life
Best RAID5 explanation I've seen
Excellent video, clear explanation. It's nice to see Nataraj idol behind you.
Great video !!! understood very well the concept of RAID !!! Thanx a lot
That turn at the end. Totally awesome :DDD
Very Informative.Great video, Recently I've been learning a lot from ur videos. Very good Eli! U put alot of effort into these videos! Thank You Very Much.
Finally, At the end of this video. the idol (The Lord Nataraja Swamy) is awesome.
Even though it's old its a great video and very thorough. Thanks for the help.
Eli, you are the best... great job
Loved the chair swivel at 32:25 , you should be called Don Eli after that beauty
.....Now i know ....Eli u re such a goooooood tutor....lov your video classes....thankx dude.
Awesome nice nice, always the best
very good lecture....i keep on downloading all your videos to my hard drive..i have separately bought new hard drive 500gb only for downloading Eli lectures..
You're great explaining :) Thank u so much!!
Very well explained Eli. I appreciate your efforts.
Nice job on explaining raid, size, and volume. I am going to apply them on my 8x HP DL360 5G serversfor hands on.
nice video..as a side note.. on tinkering with a raid, in an event of a failure, you want to make use of the logs.. this helps in identifying the failed disk, flash the drive to make double sure it is in tandem with the log..Next, if possible, backup the entire volume before attempting any hot swap..
Hi Eli.. Thank you so much for this knowledge sharing.. What you give comes back.. God bless..
I always always confused about RAID 5 until now. Thanks!
thx eli for explaining in such detail!!!!by the way i also liked LORD SHIVA in brass behind u!!!!
Dude. This lesson was a really super informative.👍
Great video, thank you.
Simply awesome :)
Raid 0 = Stupid, good idea, but to risky.
Raid 1 = Awesome Idea, great to keep things running.
Raid 5 = Safer, my preferred choice (with sacrifice of space)
Raid 10 = Beatiful. :')
Great vids all round..Many thanks, Recently I've been learning a lot about Actifio (Copy data management) a comparison with say EMC would be great if you have the time big chap!
Was a bit confused about RAID, thanks for making it so clear.
Is that a pun i see
Any time i need computer help i go to my guy Eli!..thanks dude
Awesome dude, very logical.
Thanks ..Excellent & clear explanation ..
Excellent Explanation thank you.
Great explaination!!!
Eli. I appreciate You....You are toooo Good......I am becoming your Fan....
Pretty good man! I'm sure alot of effort went into the vid! Congrats!
Thanks for sharing the knowledge.
Your explanation is the best. thanks
Great video.
Watching in 2018, when he said the max drive at the moment was 1TB, I realized we’ve come a very long way.
Watching in 2021, it’s like holy shit. There’s such a thing as a 240 gigabyte hard drives? Wow, that’s really small! I got like 8 terabytes on one hard drive.
Greate video!
Always learn from ur
vids cheers
you're a legend Eli
Technically its Redundant Array of Inexpensive Disk, the "Independent" is a more recent reference to it but as were tested in College the correct name is "Inexpensive", but its good to know both.
thanks man, all ur videos are gr8
I wish you was my instructor :)
I get enough about Raid. Thank u bro.
i like your videos, very good training.
Greets,
eli, you are such a teacher!
wow...my textbook was way more complicated than this...now i got a clear picture thanks ELI
All you people thinking about RAID 0 being "unsafe" just because you don't get the redundancy: the amount of read-write cycles per drive decreases with every disk you have in the array, so if you have a large amount of small drives, RAID 0 may actually allow these drives to live the maximum possible life they can get (called MeanTimeBetweenFailures), plus you get the benefit of using those "first read - first write" speeds at all time.
Very well explain...Thx a lot
"one really big 1TB hard drive", hehe, funny hearing that in 2018
I just bought 16 terabytes for a home server for $600 CDN. Crazy stuff.
Thank you. Working on making a san/raid out of the 4 pi that run the greenhouse. Need a controller to switch gpios to back up. And a stand by power source in case of greenhouse solar failure.
it really helpfulllll thumps up man
Oi Eli Mottai you rock .... keep it up :)
Thanks Eli your awesome !
you are good, consistent and clear Thank you, do you teach 7 layers networking?
only subscribed that I can do for appreciate your work
Hello sir,
Thanks for the nice tut.i have a question though. Regardless of which raid you use , on which of the harddrives will the Operating System be installed ?
e.g. raid 0 : is disk striping, if one hard drive fails nothing will work.
where do you chose to9 install the OS ?
thank you Eli
Mirroring sounds great. But once you pull out that failed drive, put in the new drive, and it is rebuilding, it seems like all your eggs are now in one basket until the new drive is fully built up to again mirror the drive that's been working the whole time.
Thanks for the vid.. I have a question... Is fault tolerance the same as redundancy when it comes to RAID?
in regards to size and allocations in a raid 5 is it possible to partition HDD to be used in a raid 5? eg a 500, 500 and a 1TB can the 1TB be partitioned to x2 500GB?
Nice Video it helps me a lot
Question - When using disks of different sizes - You are limited to the smallest HD. Could you partition the other, larger drives for use? Either for a larger array or just extra usable disk space? Thanks in advance. Great vid btw, subscribed!
cool stuff..
redundant array of independent disks, originally named redundant array of inexpensive disks

Excellent Explanation thank you............ Can we use C drive as RAID?
NICE idle its my favorite god idle NATARAJAN god idle its very nice Eli
Thanks for the video, Eli. Is it true to say that RAID 5 is a "hybrid" of RAID 1 and 0? (Even though RAID 10 is really RAID 1+0).
When using different sized hard drives can a second volume be created using the unused space of the larger drives?
good stuff
Eli the great.
Hola, muy interesante video, la funcion de hot swaple solo funciona con el raid 5???
Striping = bits, thanks for this I was totally confused.
In raid 1 you say I get no better performance than with a single hdd. I understand this when the computer is writing to the discs. But when reading from the discs it should without a problem be able to read different bytes from each disc and that way double the speed of reading?
You have Nataraj statue at your back ..impressed
