Ok, let me ask the question again...

I have 2, possibly 3, 320gig SATA drives. I want to build a RAID array that 
will maximize the speed of read and writes to the array. I have no concern 
with redundency because I will archive what I wish to keep to another drive.

Using mdadm or lvm2, what type or RAID setup should I use?
