One is a proven, well-known technology with a lot of options out there,
the other gives you a much better dollars-to-gigabytes ratio and maybe a
better future.  (Though SCSI has a *lot* of momentum.)

If it's gonna be handed off to another sysadmin, use SCSI.

For SATA, 3Ware then.  Though Linux MD RAID is consistently competitive
with hardware RAID, with no worries about weird UIs, proprietary formats
or quicky finding a replacement RAID card.

Last server I built ended up using SCSI because it was built into the
mobo, and we weren't buying enough storage for the savings to cover the
cost of the SATA card.

Actually, some SATA drives are consumer-quality short-warranty models,
and others are server-quality 5-year models.
