Tom,
This is a story that is evolving. Anyone else use StorageReview? Great
comprehensive drive benchmarks:
http://www.storagereview.com/
Check the comparisons between 15K RPM SCSI drives and the 2004 Western
Digital 10K RPM SATA (Raptor) drives. The Raptors are an interesting hybrid
of SCSI-related tech and desktop tech, and were some of the first drives
with SCSI-like command queuing TCQ/NCQ.
I think the last remaining issue in moving to SATA for all enterprise use is
the lack of decent SATA controllers, though 3Ware (http://www.3ware.com) is
getting there:

Although the benchmark numbers are pretty good, they have only published
(what looks like) results for sequential IO. It would be interesting to
see the random ones, as this would tell us how effective the TCQ
implementation is.
Cheers
Mark
