Good 👍🏻
Almost 1.5 millions subscribers! Keep going!
Thx lot for your videos:)
Remember RAID is NOT a backup...it's redundancy. Good video.
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
For the longest time I couldn't understand the concept of RAID 5, the this animation helped immensely. Great video!
Glad it helped!
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!
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.
One of the best channels I have found on TH-cam regarding these tech topics. Highly focused on explanations for dummies. I love it! Thanks :D
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!
Was literally trying to understand what parity is yesterday then you dropped this, the timing couldn't have been any better. Thank you!
Perfect!
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 ❤
I prefer to buy your course than Brilliant if you have courses about network. You explanation is way better than others I saw before.
Pls don't stop, you are one of those guys who will teach you with really easy way love it
Even despite how its simple but yet it made me binge watch every single videos this guy makes its too interesting
Compact, simple and simply beautiful.
Thank you for these.
Glad you like them!
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❤👏🏿👏🏿👏🏿👏🏿👏🏿
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.
Very well explained. That simplification with 1 byte is genius because everyone can understand it.
my mind has now clarity about parity in RAID. Great!!!!
Congrats on your 100th video!
Can't believe you dropped a new video! I've been using your videos in my classes. They're great!
For a split second, I thought this video was about Ditty and the heading said RAID PARTY !!!! 😂😂😂🤣🤣🤣👍👍👍👍
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
It looks simple (only when you explain it).
Thanks!
Thank you, Sir! I never get bored watching your lessons
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!
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
@@JustGolight:skull:
Now for today's spons-
Understood this Raid concept very easily.
Your explaining way is really superb!
Thanks a lot!
Supremely instructive video! Thank you!
Just in the process of migrating from a Synology to a homebuild NAS
and this is also interesting because I'm gonna use RAID5.
Thanks, it is super clear, If you don`t mind. I would like to make subtitle for Korean guys.
Best explanation out there! Thanks!
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?
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 .
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.
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.
Thanks a looooooot, you give information in very easy way, i appreciate it
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.
Wow, amazing teaching, awesome.
This was a great video, thanks so much
its also called redundant array of inexpensive discs
Love your videos!
Great RAID video
how come top paid courses don't teach this! best youtube channel ever
Really nice explaination
awesome explanation thank you power cert
Man, these videos are so fun to watch but they're also easy to understand!
Thanks, very simple explanation .. Could you make a video explaining other types of RAID such as Raid 10 ?
Great explanation
Thnx for the explanation u r great ❤❤
As always: Simple but memorable 🙂
Perfect video but I expected to explain all the other backup systems as well
Thank you very much!
Thanks for the info
Amazing content.
Very helpful!
Great video
yoo it's new powercert video!
Time well spent.
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?
very useful video
very nice video
Thank you for such a great work! Which app you used to create such nice slides?
thank you!
hello, love ur content. Can you make a video about instrcution set architecture?
Nice video❤❤
Love it
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?
This guy knows stuff...
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 .
brotha still going in 2024 😭🙏
god bless man.
Nothing else to say, but thank you.
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
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)
Can you do video on Optical transport?
Hey there luv ur videos i need animated video on snmp and ntp will u make one pls🤗🤗 and also ""compTIA server+"" plzzz..!
bro i have to memorize all these but there so much
Hi sir can you make a video on virtual memory
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?
pls make a video upon NetBIOS, I've confusion what actually it is!
600% of computer knowledge in my brain
Sir, Pls tell me the Software / Application you use for the Creation of the Animation videos like this
What is SIP & how is it different from VoIP if at all ?
If the parity part really is THAT simple, it's very deceptively simple.
Smart
how does RAID 6 calculate the parity to allow for 2 disks failure then?
How does dual parity work?
I thought R.A.I.D. stands for Redundant Array of Inexpensive Disks.
Am I wrong? ..
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.
So basically it's like solving for 'x' in an algebra equation
👋👋
Sir, I have domain name, where i have my php files under public html, and i used those php files as API, i request them from android application which i developed, but for some devices, it works well, but for some devices UNKNOWN HOST Exception occurs, i resolve this error by turning aeroplane mode on/off then this exception goes. i dont know why this DNS problem coming in android phones. please help, how android phone DNS works
Wrong video my dude....
How about a t-shirt with the picture of a motherboard saying "Is your computer's mother excited or board?"
hmm..good idea
When raid 7?
Excellent video, a big thank you for putting his content out there.
