Hello there

Why SCSI U320 10k rpm drives maximun transfer rate is 72 MB/sec. Aren't the'y supposed to go at 320 MB/sec.

Or maybe I'm confused about that :confused:

I think BIPolar might help here...but, that is what it is rated at.
I belive you only get that kind of performance when multiple drives are used in conjuction with eachother...in a RAID array...

Oh...and I believe those speeds are from the Ultra 320 in the 15K spindle speed variety.

Look at page two:

You don't need RAID, but three or four drives transferring among one another will fill the bus (320MB/s). One drive doing nearly 90 ain't bad at all. :cool: btw, what's your SCSI controller?

The controller is board integrated based on adaptec aic-7902w chipset.

The motherboard model is Gygabyte 8knxp ultra unfortunately revision 1.0
