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.🔥🔥🔥🔥
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.
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.
Finally I could grasp the point behind the PARITY. Brutal convenient and exact explanatory animation with simplistic narration. Bravo my friend. Bravo 👏👏
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!
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❤👏🏿👏🏿👏🏿👏🏿👏🏿
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
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.
Hello I spent two whole days watching videos and reading ont this topic and just could not understand it but when I watched this video I was able to grasp the information. Thank you very much
Thankyou for the information Love from India🇮🇳 I face lot struggles to study CCNA, but your videos are absolutely beautiful, your explanation is very good and reaches to poor people like me without any cost. I dont know how to thankyou... But i can included in my prayers.. Your way of approach to explain hard things are inspiration to me.🎖️🎖️🎖️🎖️🎖️ Keep going on... We need 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 .
Hello out there, l just want to tell you, your videos are the best and short, in a way that a simple braim can understand. Much love from 🇹🇿, and l am one of your greatest subscribers with a lot of your videos on my device. Keep it up.
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.
I love your videos! They are so helpful and so easy to understand. If possible could you do a full course on Security+ please and CySA + please? Many thanks xx
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?
When one drive fails, your computer keeps chugging along, as if all is well. That means that your remaining drives continue to have their contents changed, because you can keep using your computer as if nothing is wrong. And you can go on that way, with no issues (as long as another drive does not fail). Then, when you replace the failed drive, it gets rebuilt, with everything you have been doing on your computer during the failure period. And on top of that, while the replacement drive is being built, you can keep using your computer, and somehow the RAID controller is managing it all, so that you lose no data, and your replacement drive will eventually become part of the RAID (making you fault tolerant, again). I understand how it works. But engineering it fascinates me. The people that actually designed the RAID controllers, and wrote the controller's code, are brilliant. They might not know how to tie their shoes. But they are brilliant.
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?
Great video! Curious now, if you had a raid 1 setup and wanted to switch to a raid 5 or 6 set up. If the power went out while you were in the middle of the transition, what would happen to your data? Would all be lost?
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
? In the simplest scenario with the 3 disks, how to read data if perity is spreaded among all disks? From Example 1, we have byte "1_0_0_1_1_0_1_0", potentially each of them could be parity, so how to retrieve original value? I thought if we need extra bit to represent flag (parity or not), so it will take 2x space (parity bit, and bit for flag). Thank you in advance
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?
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)
@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.
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 .

Glad I could help!
For the longest time I couldn't understand the concept of RAID 5, the this animation helped immensely. Great video!
Glad it helped!

One of the best channels I have found on UA-cam regarding these tech topics. Highly focused on explanations for dummies. I love it! Thanks :D
Was literally trying to understand what parity is yesterday then you dropped this, the timing couldn't have been any better. Thank you!
Perfect!
I prefer to buy your course than Brilliant if you have courses about network. You explanation is way better than others I saw before.
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❤👏🏿👏🏿👏🏿👏🏿👏🏿
Even despite how its simple but yet it made me binge watch every single videos this guy makes its too interesting
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 ❤
Congrats on your 100th video!
Compact, simple and simply beautiful.
Thank you for these.
Glad you like them!
Best explanation out there! Thanks!
The last minute of this video (the method for four or more drives) explained exactly what I needed and was delivered clearly and concisely. Thanks!
Pls don't stop, you are one of those guys who will teach you with really easy way love it

Very well explained. That simplification with 1 byte is genius because everyone can understand it.
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.

Can't believe you dropped a new video! I've been using your videos in my classes. They're great!
Understood this Raid concept very easily.
Your explaining way is really superb!
Thanks a lot!
Such an elegant explanation. Thanks a lot!
I’m in the trenches right now cause I lost importants data in a disk five setup😅. Thanks for the video ❤
Thank god it's not RAID Shadow Legends...
This video is sponsored by RAID SHADOW LEGENDS
😭😈😈💀💀
Shush XD

Now for today's spons-
I love your videos! They are so helpful and so easy to understand. If possible could you do a full course on Security+ please and CySA + please? Many thanks xx
best explanation of how Parity works.
For a split second, I thought this video was about Ditty and the heading said RAID PARTY !!!! 😂😂😂🤣🤣🤣👍👍👍👍
This was extremely helpful and easy to follow along. Thank you
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 .

These videos are amazing I'm so glad I found them and you!
I love you animations so much! They are clear and fun to learn with!
Nice. I always recommend your videos to my computer networks students.
Thanks as always, I never miss your videos!
I appreciate that!
Just in the process of migrating from a Synology to a homebuild NAS
and this is also interesting because I'm gonna use RAID5.
Supremely instructive video! Thank you!
clever way to use this to rebuild data using parity
Wow, amazing teaching, awesome.
As always: Simple but memorable 🙂
how come top paid courses don't teach this! best youtube channel ever
Thanks a looooooot, you give information in very easy way, i appreciate it
Thnx for the explanation u r great ❤❤
Always love your work. Thanks for the share.
awesome explanation thank you power cert
Thank you. It was very clear.
TRUST ME MAN YOU ARE THE BEST

Thank you for such a great work! Which app you used to create such nice slides?
Time well spent.
its also called redundant array of inexpensive discs
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?
Thanks, very simple explanation .. Could you make a video explaining other types of RAID such as Raid 10 ?
Great explanation

Thank you very much!
This guy knows stuff...
Great RAID video
Man, these videos are so fun to watch but they're also easy to understand!
Perfect video but I expected to explain all the other backup systems as well
yoo it's new powercert video!

Hi sir can you make a video on virtual memory
Great video
very nice video
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?
Thanks for the info
Sir, Pls tell me the Software / Application you use for the Creation of the Animation videos like this
Thank you!
600% of computer knowledge in my brain
So Parity is spread out while Mirroring uses a whole drive, right?
What is SIP & how is it different from VoIP if at all ?
brotha still going in 2024 😭🙏
god bless man.
Very helpful!
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)
Thanks
Hey there luv ur videos i need animated video on snmp and ntp will u make one pls🤗🤗 and also ""compTIA server+"" plzzz..!
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.
thank you!
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 dual parity work?
