are there any good desktop disk drives these days? by

I'd like to buy a quiet, reliable hard drive for a desktop PC.
Capacity, speed, and $/GB are unimportant (within reason). I get the
impression that all the standard ATA-type desktop drives are complete
crap, and not intended for heavy use (continuous power-on even without
a lot of i/o). I looked...

IOPS from RAID units by
davidhoffer
The IOPS the array can deliver is the aggregate of all the drives in the raid group less the hot spares and parity drives. Its more complicated than that of course but its a not bad rule of thumb. So 10 data drives that can each deliver 100 iops could (in theory) deliver 1000 iops when bound...
