Hi Josh,
Any chance that it's a hardware problem causing a SCSI level slowdown?
i.e. termination accidentally turned on for a device that's not at the
end of a SCSI chain, or perhaps using a cable that's not of the right
spec? Stuff that will still let it work, but at a reduced rate. Maybe
even a setting in the Adaptec controller's BIOS? Might be worth looking
at dmesg and seeing what it reports the SCSI interface speed to be.
:-)
Regards and best wishes,
Justin Clift
