That's pretty slow for modern equpment.  I usually see 60+MB on single
or software-mirrored scsi and 40-60MB on IDE (don't have
any raided IDE...).  Be sure you have good 80-wire cables and
you see something like:
hda: 195371568 sectors (100030 MB) w/2048KiB Cache, CHS=12161/255/63,
UDMA(100)
in dmesg.

That may not be the real problem, but it is something you
should be able to improve.
