    Remember RAID is NOT a backup...it's redundancy. Good video.

    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!

  • @ThioJoe

    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.

  • @NoEgg4u
    @NoEgg4u 3 місяці тому

    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.

    ? 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

    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 .
