If you need extra disk throughput, you can either use the LVM, or
external raid cards. I've had good experiences with ide raid cards
from 3ware.

You can increase streaming rate by striping, and with some setups
(3ware included) you can increase seek performance with mirroring
(although it takes 2x the disk space).
