Why? 1TB and up is a SATA niche. You can buy 3 SATA arrays for the
price of 1 SCSI array.... Also... gigabit Ethernet is only 125MB/s
(Max) and and a single SATA drive can easily transfer at 50MB/s*. Your
limiting factor is probably going to be your bus with arrays/GigE so
SCSI is pointless unless you can take advantage of SCSI's TCQ with
high random access I/O loads, If you shift your work loads around you
can probably get around this. SATA is so cheap and good enough that we
will do whatever it takes to make it work... SCSI is already dead in
the entry level server market.

*I just tested this with two Maxtor SATA drives the other day:
dd if=/dev/disk1 of=/dev/disk2 bs=4m. It dropped off to about 30MB/s
at the end but my average read/write was just over 50MB/s.
