If you don't mind me chiming in, my disks arn't nearly as slow, but I expected them to be faster. Can anybody make a recommendation to improve my disk i/o, or confirm the speeds I get are about right? This is the first machine I've had thats U320 SCSI-capable.

If I wanted increased speed on my system fs's, would a raidframe raid5 do me any better?

Thanks anyway..
