Scsi vs Sata Which one would be better for me ?

- Parallel SCSI is dead
- SAS is great for heavy load (high RPM for high throughput and low seek latency, tagged command queueing is also a good solution for multiple simultaneous I/O jobs) but very expensive and runs hot
- SATA is a very good solution for desktop and workstation usage (even simpler servers) - very good cost/performance ratio, high capacities; if native command queueing works it even makes up for the traditional command/response bottleneck of multiple I/O

Go SAS when you require the highest performance you can buy, but prepare for paying several times the price of SATA.

Why swap? RAM's so cheap there's no problem throwing 4 Gigs (or even 8 with a 64 bit OS) on the board. Less spent for RAM than for a SAS HBA alone - and waaaay faster.
