The concept that SATA subsystems will tend to consume more CPU cycles because SCSI controllers untrue. SATA disk consumes really small amount of CPU under FreeBSD. even if it's less than on SCSI controller it is still very little. ___ freebsd

I have a SCSI controller, two cd-rom drives and the external tape streamer on my workstation. No SCSI harddisk anymore. A 18 or 36GB harddisk is likely to be the SCSI-2 standard, this is the controller I have. In the past it was quite a speedy interface, but I guess even the older ATAs

i've heard scsi hard drives are really good. i've also seen at least one site which claims that ide easily outperform scsi. for the server we got (dual P3 1GHz 2M which will use raid), is one preferable over the other? and what about sata? -- In friendship, prad

i've heard scsi hard drives are really good. i've also seen at least one site which claims that ide easily outperform scsi. I seriously doubt that. Maybe if you take a single old first generation SCSI disk and compare it to a modern IDE drive. But that's not exactly comparing apples to apples

i've heard scsi hard drives are really good. SATA are too. i've also seen at least one site which claims that ide easily outperform scsi. the performance are similar by interfaces, SCSI drives tend to have higher RPM and faster heads and can be 30-50% faster for 5 times higher price
