RAID5 is not the best for performance, especially write performance.
If it is software RAID it is even worse :-).
(Note also that you need to check that you are not saturating the
number of seeks the disks can handle, not just the bandwith.)
Striping should be better (combined with mirroring if you need the
safety, but with both striping and mirroring you may need multiple
SCSI channels).
