Good 👍🏻
thank you so much...back in hardware class i was confused with parity thing...
teacher said just "arithmetics calculations" and refused to elaborate further...
you just came here to clutch again.🔥🔥🔥🔥
Happy to help
Finally I could grasp the point behind the PARITY. Brutal convenient and exact explanatory animation with simplistic narration. Bravo my friend. Bravo 👏👏
Glad I could help!
Remember RAID is NOT a backup...it's redundancy. Good video.
Best IT channel on the platform makes everything so easy to understand and to follow along , also helps seeing how things work , you tha GOAT ❤
For the longest time I couldn't understand the concept of RAID 5, the this animation helped immensely. Great video!
Glad it helped!
What I don’t understand is why no one has created a system where there’s just a bit more than 1 disk of parity (or 2 for RAID 6), to account for unrecoverable errors. As it stands with RAID 5, if you have 1 disk failure, but ANY of the remaining disks has an unrecoverable error in one of the sectors, even if it’s a few KB, the whole array will fail. So why not allow having 1 disk + a few extra megabytes worth of parity to handle that? Even if using RAID 6, Seems like a no brainer to trade a tiny bit of additional storage for the protection from UREs.
Or at least there’s nothing like this that I could find yet.
The best youtube channel on the entire internet. I'm pretty new at IT-System Administration and a lot of things are still too abstract for me. The way you explain it makes it so much easier to comprehend, sure thing there's still a lot to learn and this might be just basics, but basics I struggled to understand in depth. Thanks to you, not just it's great starting point but also it makes so much fun. I can't believe that your 10-minute videos can explain in a simple way things I had difficulty with even after listening to it for a whole semester at university. Sir, you trully rock, thank you for this incredible work!
how come top paid courses don't teach this! best youtube channel ever
Thank god it's not RAID Shadow Legends...

Shush XD

Now for today's spons-
Was literally trying to understand what parity is yesterday then you dropped this, the timing couldn't have been any better. Thank you!
Perfect!
Your videos are always amazing. Watched your channel for our 10 years since I started my IT to cyber/info sec profession. This knowledge always helps in my current work and as a refresher. Thank you❤👏🏿👏🏿👏🏿👏🏿👏🏿
I prefer to buy your course than Brilliant if you have courses about network. You explanation is way better than others I saw before.
Compact, simple and simply beautiful.
Thank you for these.
Glad you like them!
Please, if you ever consider writing a book with all the topics you've covered in 2024 and the years before. I would buy it 100%. This information and the presentation of it deserves to be on a hard copy book.
Even despite how its simple but yet it made me binge watch every single videos this guy makes its too interesting
Congrats on your 100th video!
my mind has now clarity about parity in RAID. Great!!!!
Very well explained. That simplification with 1 byte is genius because everyone can understand it.
Can't believe you dropped a new video! I've been using your videos in my classes. They're great!
It looks simple (only when you explain it).
Thanks!
The most fascinating part is that i have subscribed this channel for so long ,and watched all of them along when you post new videos.BTW,i am not advertising something,but i really recommend Brillant for those who want to learn the working principle behind the neural network
For a split second, I thought this video was about Ditty and the heading said RAID PARTY !!!! 😂😂😂🤣🤣🤣👍👍👍👍
Best explanation out there! Thanks!
I’m in the trenches right now cause I lost importants data in a disk five setup😅. Thanks for the video ❤
Thank you, Sir! I never get bored watching your lessons
Understood this Raid concept very easily.
Your explaining way is really superb!
Thanks a lot!
These videos are amazing I'm so glad I found them and you!
Maaaaaaan , now i finally understand how parity works 😂 thank you , if you make professional certifications paid courses I'll be one of the first buyers .
the only channel that make me confedence with the new information ... you helped me understand many things whenever i struggle in course about computer networking .
but i wonder if is there a video about switching techniques?
Supremely instructive video! Thank you!
I love you animations so much! They are clear and fun to learn with!
Thanks as always, I never miss your videos!
I appreciate that!
Nice. I always recommend your videos to my computer networks students.
Always love your work. Thanks for the share.
Wow, amazing teaching, awesome.
Just in the process of migrating from a Synology to a homebuild NAS
and this is also interesting because I'm gonna use RAID5.
This was a great video, thanks so much
Thanks a looooooot, you give information in very easy way, i appreciate it
awesome explanation thank you power cert
Really nice explaination
Thnx for the explanation u r great ❤❤
Great explanation
Can you please create updated version of CompTIA A+, Network+, Security+ Certification course !! that would be really helpful, the way you teach it's just so easy to understand and remember.
Even if it's paid.
Love your videos!
Thanks for the info
Thank you very much!
Amazing content.
Man, these videos are so fun to watch but they're also easy to understand!
Very helpful!
Perfect video but I expected to explain all the other backup systems as well
As always: Simple but memorable 🙂
Great RAID video
Thank you for such a great work! Which app you used to create such nice slides?
Great video
Time well spent.
hello, love ur content. Can you make a video about instrcution set architecture?
yoo it's new powercert video!
Nice video❤❤
very useful video
That really simplifies things when understanding RAID parity for me. I'm early on in my studies - but is this XOR calculation the same calculation that is used in ECC RAM?
its also called redundant array of inexpensive discs
Love it
brotha still going in 2024 😭🙏
god bless man.
very nice video
Can you make a video on Mac address randomisation
This term I came across a device like USB type a/c to lan adapter, the moment I connect it to different CPU I can different Mac address. (HP type c to lan I faced this)
I used one more from tp-link where I did not face issue of Mac address variation.
Please see if you can make a video on this
can this be done with a hdd and a m2 ssd and a sata ssd mixed? or do they all have to be the same disk type? also when they are combined like that, if the disks are different which read/write speeds are inherited?
Can you do video on Optical transport?
This guy knows stuff...
Nothing else to say, but thank you.
i really like your videos. good explanation. just a little marking mistake at 4:17 in the xor table. have a nice weekend :)
I don't see a mistake. Please explain.
@@PowerCertAnimatedVideos on the left part it is 1 1 0; but in the XOR table is marked 1 0 1
The chart does not correspond to the order of the disks. The Disk A is the first bit (1), Disk C is the 2nd bit (0), and Disk B will be the result which would be (1)
pls make a video upon NetBIOS, I've confusion what actually it is!
600% of computer knowledge in my brain
What is SIP & how is it different from VoIP if at all ?
bro i have to memorize all these but there so much
Hey there luv ur videos i need animated video on snmp and ntp will u make one pls🤗🤗 and also ""compTIA server+"" plzzz..!
How does dual parity work?
How many of your drives have spontaneous caught fire?
Too many :)
@PowerCertAnimatedVideos you should look into that problem. You're probably dumping too many amps into them. Something is wrong with your breaker, your surge protector, or your PDU system has an issue.
Smart
The problem with just raid alone is bit rot , if the whole drive dies you can use the parity to remake drive , but if there is a read error because it doesn't know which drive made the error all it does is write a new parity .
how does RAID 6 calculate the parity to allow for 2 disks failure then?
Hello sir osi model and tcp ip model please
I thought R.A.I.D. stands for Redundant Array of Inexpensive Disks.
Am I wrong? ..
If the parity part really is THAT simple, it's very deceptively simple.
When raid 7?
So basically it's like solving for 'x' in an algebra equation
Teaching millions and scraping up YT and ad money from sponsors demonstrates the will to teach despite this man's time for animating, voice over and time. Teachers are underappricated and underpaid.
👋👋
You got the parity checks incorrect in your explanation!!!

How about a t-shirt with the picture of a motherboard saying "Is your computer's mother excited or board?"
hmm..good idea
Bgp.
I don't know too much of this techno babble rabble. I just use my I phone
Excellent video, a big thank you for putting his content out there.
