That read speed is quite poor.  I would expect to see better speeds than that 
from a single S-ATA disk!  For several years people have been reporting 
better speeds than that from 3ware controllers (although almost no-one tested 
with as few as three disks).

But hdparm is a poor benchmark tool.  I suggest using Bonnie++.
