Make sure you click the link here to check it out. This video is about RAID five and RAID six, which are more practical for professional applications and less practical for home users. Just like RAID one, RAID 5 is for protecting your data in the event of a drive failure. It requires at least three drives to operate with one of the drives being reserved to rebuild the data on the array if it dies. So if you had say for example six drives, you'd have the capacity of five drives. Because it stores data on multiple drives, you can read from it extremely quickly, making it great for archiving large amounts of data. However, without a complex hardware RAID controller, writing to a RAID 5 can be much slower. And rebuilding the array once a drive is failed and you replace it with a new one can be timeconuming. RAID 6 is kind of like a more durable version of RAID 5. It can survive up to two drive failures out of the entire array and still be completely rebuilt. That means, however, that you have to have at least four drives and it is much slower to write than RAID 5. So, pretty much unless you have a complex hardware RAID controller, you can't really run RAID 6. When you're running four drives, it's really impractical compared to something like RAID 10 and is more designed for professional applications where a large number of drives are built into larger arrays. If you're watching this, you've probably watched our video on RAID zero and one already. For consumers, RAID one's fine. If you're running only four drives, RAID one will give you 6 TB of usable space using 3 TB drives. RAID 5 gives you a bit more space, but you write to it much slower, so it can be useful. But RAID 6 gives you only 6 tab of space, and it's much slower and requires one of these bad boys. The numbers start to look very different once you move up to an eight drive configuration. However, RAID one will give you 12 tab of usable space only. Half of your drives are used for redundancy. RAID 5 gives you 21 terabytes of space and RAID six will give you 18 terabytes of space. Plus the fact that RAID five can sustain one failure and RAID six can sustain two failures. Hey guys, thanks for watching this episode of As Possible on Techquicki.
