SCSI hasn't offered any significant performance advantages (over ATA) for a very long time
I've got a 3xSCSI RAID 5 array on my server, and same-speed ATA drives on my (home) desktop computer. I'm constantly rsync-ing between the two--mostly up, but sometimes down--the identical 43GB of data. The difference in speed of response in these totally disk-bound operations (ie at the start of the rsync) is astounding. It has been so significant that I've seriously considered moving my home computer to SCSI. Only the cost has, so far, kept me back from doing it.
