Two reasons:
1) Throughput, particularly on read. Striping across several
disks means I can move more than one drive's max data rate at
once (right?).
Uhhhmmm...isn't that "performance"?
I'd say it is; I never said performance wasn't a concern. In fact,
I said throughput was my #1 concern, followed by data safety, and
that only uptime wasn't so much a concern. (I did say /write/
performance wasn't as much of a concern, which may be where Mr.
Fickenscher misinterpreted me).
ACK! Forgot to add this to my last message:
If read performance is a concern, instead of getting more disks for a
RAID, you could also use that money towards better disks, such as
raptors. I seem to recall tests where a single raptor outperformed a
2 disk raid 1.
