ayup. By going from SCSI-1 to -2F, you went from 5 MB/sec to 10 MB/sec. Still less than the actual capability of that diameter & rpm drive tho - that's what faster SCSI's fix. :)
what does SCSI-1 tp 2 F mean ? first or second scsi bus or what ??? L
The PCI can burst at up to 264 MB/sec, far faster than the attachment (ATA, SCSI, etc) interfaces can do. You could throw in a couple of fiber channel cards, 100 MB/sec each...
As for OS X... Well, it's i/o kernel is bored. The problem is the crud Apple added to make FreeBSD/Mach look/feel pretty -- it needs supercomputer-class processors and boatloads of RAM.
