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 :(
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!
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!
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!
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!
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.
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.
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.
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.
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.
RAID 6 exists not for two drives failing under normal situations but in the situation of a single drive dialing and then the rebuilding process stressing the remaining drives pushing another drive over the edge during the long rebuild times modern high capacity drives require. Keep in mind that when you create a RAID volume, you’re using drives of similar vintage. When one drive fails it usually means the others are not far behind. Expect more drive failures. Usually when a drive fails after several years of use it’s a good time to migrate all the storage to a newer, faster, higher capacity RAID. THe double redundancy helps assure the migration can complete before more drives die.
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
Not sure how I came across these short, clearly explained PowerCert videos. Sure would have like to have this when I was in the business. Most books, classroom learning far to complicated and boring.
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
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?
Great video! However, I would recommend to add the real con of re-build 5/6 and the real wold usage on raid 5 and 6(more than just 3/4 drive). I can see people choose raid 6 for their 4 drive array after watch this video without thinking about the performance benefit and much lower rebuild time of raid 10.
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.

Not only the Raid explaination is on point but the powerpoint animation is next level.
I wish you could teach a hands on class of all your knowledge. Thank you for sharing/helping computer guys all around the net(world)
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
Nobody does it better! He was awesome before but with the new funny animations and word balloons it's just epic now. Fun and insightful. Smiles.

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

You are simply the best. You are the only one who makes videos that don't need to be played twice to be understood.

Have you seen 2 way mirroring, 3 way mirroring?
Studying for mine right now. What resources did you use to study??

Thanks for very cleared explaination about RAID 5, 6 . I also like your animation.
You sir make the best animated videos and your explanations are also best. You help me out a lot! Thank you! Hope to see even more uploads from you!
It took me YEARS to find a good explanation to understand RAID 5 AND 6. THANK YOU SO MUCH FOR THIS!

This is best teacher Online really very good and clear information
Excellent Information & Explanation, I'm learning new things from you. Thank you
As usual, very easy to understand explanation and video. Keep up the good work man!
WOW!!! great learning enforcement resources!! I learned about RAID in 5 mins instead of reading 30 pages. The visuals definitely help. This awesome!!!
You make everything easier to understand! I'm glad that I found your channel ♥
Good explanation, nice video⭐
Keep going!!!☺
I absolutely LOVE your powerpoint animation skills

Would you be able to make a video about sub-netting and subnet masks? Your videos are amazing. Thanks for your hard work!
This was difficult when reading text books but u made so simple God bless you!!!
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
This is the BEST video ever on RAID 5 and 6. Perfectly explained. Finally, I understand.
You explained it incredibly well, I finally understand it fully and can memorize it well thanks to your video!

Mashaallah you are amazing I have benefited alots from you
Genial.. Awersome!! Thanks for a great explain.. you help me to understanding more cleary! Thanks again..
By far the best explanation I have seen. Thanks!!!
Short, sweet, and answered my questions. Fantastic video.
I don't think I would've ever understood this without this video!
Great explication, thank you!
It's chef Jean-Pierre. Didn't know you where interested in networking and system administration.
best explanation of RAID files. i have see ur previous videos too . all are amazing keep up the hardwork.

It really helped to understand. I feel confident to explain it anybody after I watched this video
What an explanation video 💓! my favourite channel I swear
fantastic video sir. I don't think anybody could have explained it better.
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!
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
some people have the talent to open your mind easily and stuff the information in it.
My favorite best teacher and best motivator....
Wow really? You need to reexamine your life
Very good explanation
Thanks dear
Simple and Best ever Perfect video ❤
Easy and simple to understand thank you.
This is a really great channel. I am learing a lot and the topics are explained very well, thank you!
Thanks :)
You Are Great at Teaching. I learned and understand lots from you. Thanks a Lot.
Thanks.
This channel is my favorite.
excellent vedio.well done from pakistan
I like his detailed explanation on the pros and cons of raid 5 and 6.
This was way more clear then my university PhD professor.
I understood everything in less then 5mins
Thanks for simple and precise explanation.
Not sure how I came across these short, clearly explained PowerCert videos. Sure would have like to have this when I was in the business. Most books, classroom learning far to complicated and boring.
This channel saved me from the RAID concepts. I have a hard time understanding this in class.
Thank you so much. This has seemed like rocket science until now
Thanks you really helpful, and the animation it's just perfect thanks
All I see is awesome content as usual! Keep up the good work!😎
Thanks.
PowerCert Animated Videos no thank you for helping us!!!🙂
You are my favorite. It’s so simple to understand when you explain
Very good info... bunch of thanks...
Wow. with this channel I really found a hidden gem in the education branch of the internet
Great explanation! Thank you
Brilliant Content
As usual another fantastic video with brilliant animations explained in a simple way for dummies like me. Keep up the great work!
Hai
finally! a video that explain raid properly!!!
Such a cool channel
This presentation saved me, thank you!
Great Explanation! Thanks!
Thank you for your information and explanation！
Thank you again ! I learned new stuff again ^^

You deserve millions of likes
I'm new to this at work, thank you for your videos.
very well summarized and clear good job
A very good explanation, as usual
Thank you very much dude. Your videos are great!
Finally getting a grasp on RAID. Thanks a ton!
Thanks for giving wonderful videos, pls upload a video about 'BACKUP TYPES'. Thank you
thanks for creating the video of 'BACKUP TYPES'.
Thanks for the video!
What a good content, very good indeed, subscribed!
You deserve a double thumbs up for this video too bad youTube doesn't allow it.
Thank you for the awesome and simple explanation
professional really i love it Thank you so much!
Is there any other raid other than 0,1,5,6,10 ?
Hi your raid video is very clear and easy to understand. Are you able to come up with a video to explain how parity recover data?
Thank you for this video. Appreciate it
Best explaination, very cleary, thank you :)
Great video! However, I would recommend to add the real con of re-build 5/6 and the real wold usage on raid 5 and 6(more than just 3/4 drive). I can see people choose raid 6 for their 4 drive array after watch this video without thinking about the performance benefit and much lower rebuild time of raid 10.
It depends on the use case. RAID10 is very space inefficient.
Amazing video, thank you
