SAS v SATA

[Daniel Feenberg]

Does anyone have an informed opinion as to the relative merits of SAS v 
SATA disk drives in a Linux box doing long sequential I/O for a small 
number of processes? It looks like the cost/GB is about a factor of 3 more 
for SAS (both drives at 10,000RPM), and if the performance difference is 
only going to manifest itself in random I/O, or when many processes are 
competing for the drive, I can skip it for my current application.

Thanks
