Spend all your money speeding up your disk system.  If you're mostly
writing (like my main app) then that's your bottleneck.  I use a dell
2650 with external RAID 5 on 14 spindles.  I didn't need that much
disk space, but went for  maxing out the number of spindles.  RAID 5
was faster than RAID10 or RAID50 with this configuration for me.
