I'd worry about your I/O with that setup if you plan to do anything
disk-intensive.  If you're already spending on the 64GB RAM, buy SAS.

I second this recommendation. I went with SATA myself for cost reasons (I got 750 GB enterprise SATA drives for $120 each). I guess that the best I can say is that SATA gives better price/performance.
