These tutorials are the best I have seen on this subject hands down. Complete newbie to backups, and watching these short animations, draws an awesome picture as to the differences between all types of RAID configurations and backup methods. I'd suggest watching all relevant tutorials by this person, to accommodate your needs on this topic. I gained so much in a very short time. Thank you for all your efforts, they have not gone unappreciated.
So glad I subscribed! Thank you so much for these high quality videos. They're all crystal clear to me. I watch them multiple times so I can get all the information! I thank you for your hard work!
I am a visual learner and the animation really helps. Understood it in an instant, only that it took me 4 different videos for me to finally your video :(

Currently studying for the A+ (1001) It took a while to fully wrap my head around RAID. But today I found your explanation and it cleared up a lot! You have a real gift. There’s a good balance of explaining concisely while visually showing how these processes work. Thank you so much for making these available for us!
Incredible content. Currently studying for my Security + 601 Exam and the animation showing the difference between each RAID helped a bunch. Thank you so much!
If you cannot explain a complicated matter simply, then you haven't understood it yourself yet either. This.... this is simplifying something that has baffled me for the longest of times with such ease that it's nothing short of amazing. Great job. Sure, there are other people that explain things with much, much more technical detail, but I generally don't walk out of those feeling like I actually understood anything.
wow, imagine you are a teacher, your students would learn everything you ever have to offer in 1 day lol. love it and helped so much, THANK YOU kindly friend on the internet!
In the process of getting a NAT device and trying to understand RAID Setup. Watch the older video then this one. You make these videos so well animated and understandable that even a Caveman can understand in simplicity.
This video is the one that convinced me to subscribe. The quality content here rivals most academic textbooks, trust me I'm in a networking class right now.
Your informations are too good for technology beginners . I can understand your effords on your videos ...Your lessons are very much pretty to understand those subjects .. I wish you should have more viewers on your channel. Please keep up your effords for us .. Thanks for your videos.
nice video - Our typical server setup has 8 drives. We put the OS on drives 0&1 with Raid 1, then the database data on drives 2,3,4,5 and 6 with Raid 6, and use drive 7 as a global hot spare. Not the best for performance, but we sleep well knowing we have minimal chance for data loss. I've also considered using drives 2,3,4&5 with Raid 5 with disks 6&7 performing global hot spare service (or disk 6 being dedicated hot spare to the first container, and disk 7 being dedicated hot spare for the second container), to get a little better write performance, but our environment trickles data to the RAID slowly, (control system data), and then engineers will pull massive amounts of data over time, so we like the compromise we've implemented.
PowerCert, if you could give further explanation on how parity works, as well as how does data restoration occurs from it, I think it would be appreciated by the community
thank you for the information. I feel like i understand raid 5 and 6 fairly well now. both sound better than the other depending on the situation as do some other raids, for me i think i'l prefer raid 5 for the capacity and performance improvment and maybe get a large capacity HDD for occasionally backing up the raid data and store that drive someplace compleatly disconected from whatever device the raid is connected to(i got a 4 bay enclosure with raid control built im not sure if it can be used on any computer like a Xbox one for example(technically that is a computer) sence at least some of the raid controll is in the enclosure or if my enclosure still requires connection to a pc to run some software or something, it will be interesting to find out i've heard not all enclosures made with raid controll built in control the raid in the same way in reguards to the raid control hardware). If or when i get more then 5 bays in total to use for a raid i might prefer raid 6 cuz then the performance and capacity reduction in the raid will be less of an issue assuming it's always 2 Drives raid 6 uses for parity.
The best explanation out there. If I’m using a RAID 5 for archiving, when full can I take out 1 drive for a archive / backup to store the data? Then replace the drive I took out and rebuild / delete everything on the RAID and start another archive of new data?
Very informative and concise. Sounds like RAID 5 is probably the way to go since a 2 disk failure is unlikely, faster write speeds, less required resources .
Ben Jake Yep. But bear in mind that the probability of multiple drive failures increases as you increase the number of drives (purely on the cumulative effects of probability, not because it affects reliability of drives). RAID6 is really more about higher availability.
Hi sir,your content is very useful for us.I learned alot from your channel and it gives me the clear value.my kind request is continue your posts about Hardwares and system components and system administrator videos please.I will support your channel.thank you
This is amazing! Now I understand what raids are because of your animation! holy crap. Now, I am thinking about using RAID 5 for my home video editing setup. Would you consider this raid? Is it okay to have 2x 10tb drives and 2x8tb drives in a qnap 4 nas bay set up to raid 5?
Would be more help if you could explain parity and how it is used to recover (or rebuild, are they different?) Data. But great animations. Could you share behind the scenes?
Thanks for the great video! From what I gathered, RAID 6 appears to provide great fault tolerance because it can recover from 2 disks failing. Yet the video mentions that RAID 5 is the more prevalent than RAID 6. Is this because it is not very common for multiple disks to fail in practice, or simply because RAID 5 came out before RAID 6? Is write performance generally more valued over robust fault tolerance?
I think your question answers itself. It depends on system design and budgeting. Is fault tolerance more important for you application? Or you care more about writing your data faster to the database so it is highly consistent?
Not only the Raid explaination is on point but the powerpoint animation is next level.
WAIT that is ppt? didnt even know this was possible

Yeah I've watched them multiple times too. People learn best when difficult concepts are broken down into easier visual explainations.

It took literally 10 years to find the Best explanation of RAID online. Brilliantly and Concisely explained. Thank you very much!
Then you must be impressively bad at finding information.

Thank you
oh yeah that would be just great.
i read all kinds of webpages trying to learn about parity......and he explained it in like five seconds
You are simply the best. You are the only one who makes videos that don't need to be played twice to be understood.
Ive been struggling to get RAIDs down for my Sec+ for months - your animations finally made it make sense. THANK YOU.

Studying for mine right now. What resources did you use to study??

Keep recording these type of amazing animated explanations on a variety of topics.
Hats off.
From Pakistan.
I absolutely LOVE your powerpoint animation skills

Thanks for very cleared explaination about RAID 5, 6 . I also like your animation.
Genial.. Awersome!! Thanks for a great explain.. you help me to understanding more cleary! Thanks again..
This is the BEST video ever on RAID 5 and 6. Perfectly explained. Finally, I understand.
WOW!!! great learning enforcement resources!! I learned about RAID in 5 mins instead of reading 30 pages. The visuals definitely help. This awesome!!!
This is best teacher Online really very good and clear information
Would you be able to make a video about sub-netting and subnet masks? Your videos are amazing. Thanks for your hard work!

By far the best explanation I have seen. Thanks!!!
You explained it incredibly well, I finally understand it fully and can memorize it well thanks to your video!
I don't think I would've ever understood this without this video!
All I see is awesome content as usual! Keep up the good work!😎
Thanks.
PowerCert Animated Videos no thank you for helping us!!!🙂
This was difficult when reading text books but u made so simple God bless you!!!
Excellent Information & Explanation, I'm learning new things from you. Thank you
What an explanation video 💓! my favourite channel I swear
best explanation of RAID files. i have see ur previous videos too . all are amazing keep up the hardwork.
As usual another fantastic video with brilliant animations explained in a simple way for dummies like me. Keep up the great work!
Hai
This was way more clear then my university PhD professor.
I understood everything in less then 5mins
i've been preparing for CISSP exam and can't fully understand RAIDS 0 - 10. Your videos are short and very easy to understand and funny. Thank you!
Mashaallah you are amazing I have benefited alots from you
Great explanation 😃

This is a really great channel. I am learing a lot and the topics are explained very well, thank you!
Thanks :)
It really helped to understand. I feel confident to explain it anybody after I watched this video
This channel is my favorite.
fantastic video sir. I don't think anybody could have explained it better.
This channel saved me from the RAID concepts. I have a hard time understanding this in class.
1:13 The RAID 5 animation have that bug that is show data block GHIJKL wit out Parity and will then be lose if a HDD crash.
and again at 2:43
You deserve millions of likes
Simple and Best ever Perfect video ❤
You are my favorite. It’s so simple to understand when you explain
I like his detailed explanation on the pros and cons of raid 5 and 6.
I'm new to this at work, thank you for your videos.
This presentation saved me, thank you!
finally! a video that explain raid properly!!!
Thank you for your information and explanation！
You Are Great at Teaching. I learned and understand lots from you. Thanks a Lot.
Thanks.
Such a cool channel
Hi sir,your content is very useful for us.I learned alot from your channel and it gives me the clear value.my kind request is continue your posts about Hardwares and system components and system administrator videos please.I will support your channel.thank you
Raid 6 sounds great if you got more money than problems.
Thanks for simple and precise explanation.
Easy and simple to understand thank you.
Very good explanation
Thanks dear
Is there any other raid other than 0,1,5,6,10 ?
some people have the talent to open your mind easily and stuff the information in it.
Wow. with this channel I really found a hidden gem in the education branch of the internet
My favorite best teacher and best motivator....
Wow really? You need to reexamine your life
Amazing... Best explanation ever. Very informative. Thx
Thanks you really helpful, and the animation it's just perfect thanks
Finally getting a grasp on RAID. Thanks a ton!
Thank you again ! I learned new stuff again ^^
i feel blessed ! your videos are spot on.
Thank you very much dude. Your videos are great!
excellent vedio.well done from pakistan
Great Explanation! Thanks!
one of the best animation work ... Bravo
A very good explanation, as usual
Thank you for this video. Appreciate it
Thank you so much. This has seemed like rocket science until now
This is amazing! Now I understand what raids are because of your animation! holy crap. Now, I am thinking about using RAID 5 for my home video editing setup. Would you consider this raid? Is it okay to have 2x 10tb drives and 2x8tb drives in a qnap 4 nas bay set up to raid 5?
calm down
it will set the 2x 10tb drives to only use 8tb but it will work fine
very well summarized and clear good job
Would be more help if you could explain parity and how it is used to recover (or rebuild, are they different?) Data. But great animations. Could you share behind the scenes?
thanks, excellent vid and explenaition.
Thanks a lot, the animation really helps!
Very good info... bunch of thanks...
Your Videos are awesome, ur made for this
Thanks for the video!
