Here's a link to a review comparing SATA and SCSI. It shows equal setups (meaning number of drives) of SCSI and SATA have similar performance, but the SATA setup costs 40% less. Reliability is of course a major consideration, but the SATA drives of today are probably just as reliable as SCSI drives of 5 years ago. Kind of like the worst cars of today are more reliable than the best cars of 10 years ago.

I've fairly extensively (although not necessarily scientifically) tested
SATA 150 vs. SCSI U320 and find that if you're doing a lot of random reads

performance as SATA so, for us, it's well worth the additional expense.
It's also my experience that even the best SATA drives seem to be
disposable. There's a huge difference in reliability and life expectancy
between SATA and SCSI drives because they put a bit more quality into SCSI
drives as they are expected to perform in an enterprise environment.
With RAID arrays and hotswap bays, it's easy enough to deal with SATA's
unreliability, but it's always best to not have to swap and rebuild because
every failure has the potential to cause some cascade that can become
devestating.

Were kicking around using SATA drives in software RAID0 config.
The price diff is significant. You can also get SATA drives in 10k RPM form now.,
