I have a client asking if their new computer should have SAS or SATA. Cost
isn't major issue, size is limited to 320G (each, mirrored) for SAS.
Major issues are reliabliity 3-5 years down the road, and question of
whether or not the potential speed increase is worth it (current system is
pushing 5 years old now, they will NOT use new one that long).
Some benchmarks give SAS a performance advantage and some SATA. It
probably depends a lot on the drive and host configuration. Both SAS and
SATA have different ways of going about queued commands, and I'm not sure
either is a clear "winner".
Any other thoughts on SAS or SATA?
If you just want a bunch of harddrives in a home machine, I would go with
SATA. Most machines you'll setup will already have a SATA controller.
I guess the other question would be, what is a high-end home business
machine? To me, business machine implies running office and accounting
applications, where drive speed is going to matter little.
