I'm exploring a dual drive machine running under FreeBSD 2.2.1R

Both are SCSI Ultra-Wide drives, namely a seagate 2gig Hawk and a 4gig
Barracuda.

I did some test copies between drives and the results were so so. A 50meg
binary file took about 13 seconds to copy from the barracuda to the hawk.
I'm wonderring if there is something I need to change wrt SCSI termination
or if there is something I need to tweak in FBSD.

I haven't changed the termination options on either of the drives, both of
which are on the same SCSI bus plugged into an Adaptec 2940UW controller.

Anybody have any recommendations ?

TIA
