It's very possible I was wrong. I was going on what I had heard/read
somewhere and it's possible I could have gotten confused. (I meant to
add an "I am not a RAID expert but this is what I've heard" disclaimer
to the original message but forgot to do so.)

Mirroring occasionally decreases read/write latency, but only rarely, and
only on certain controllers. True hardware RAID controllers do offer both
greatly enhanced read and write speed, on striped array, but most (90%+)
'RAID' users are actually using a form of bootable software RAID, courtesy
of their Promise Fasttrak and HPT onboard controllers. There's nothing wrong
with these, I'm using a Fasttrak TX4 myself, but they should not be confused
with true hardware RAID.
