RAID
Well, I guess none of us knew which one was which really. I thought that my hard drives would be striped, but then I saw that they were RAID 0. But then I look at the software config for my RAID support, and it says striped 16k. So then I look it up.
Turns out RAID 0 means no redundancy. So appended or striped in any combination would be RAID 0.
RAID 1 is mirroring, RAID 2 isn't used.
RAID 3 is the one with 4 drives, 3 striped and one parity.
RAID 4 is RAID 3, only with blocks instead of bytes.
RAID 5 is like RAID 4, only there is no dedicated parity drive, it is distributed.
RAID 6 is RIAD 5, only double parity.
RAID 7 is confusing.
Then you can nest these into more complex systems. But anyway, back to my point... was there a point? Anyway. Martin, they didn't mess up your brothers drive, RAID 0 just has no protection, but all the speed benefits.
