the 2650 has on onboard (ROMB) scsi raid controller built in that might
be already enabled or that you can buy an enabler kit for, in preference
to buying an extra card.

performance wise the perc3/QC has been reported to give much better results
than the perc3/DC but you might also consider software raid.

Can you tell what percentage of that is read and what is write ?  Translating
those figures roughly gives you 3Mbyte/sec average and 6.5Mbyte/sec peak which
should easily be possible on the 2650.
