Of course, which is why I included the below caveat...
I should have also suggested changing to faster drives, and/or 
increasing the number of spindles, and/or changing the RAID level (eg 
from RAID5 or RAID6 to RAID10) but I assumed the OP didn't want to be 
spending more money.

PS, depending on where the disk bottleneck is (client or server) and 
it's OS, I spent a lot of time tuning a RAID array under linux, and 
there are some things which can massively improve performance (depending 
on the configuration of your machine). If you need assistance with that, 
perhaps the linux-raid mailing list would be beneficial.

Adam
