Recommend skipping Raid 0 and just buying a 80 gig drive and using nonraid.
(1) With Raid0 you lose trim
(2) Vertex-2 (w/SF controller) works best with Intel ahci driver (not available when SSD is a member drive of a raid setup).
(3) Raid0 improves sequencial read/writes, but Does very little to improve 4K random read/writes and access time. Thereforefore does little to improve boot time and program loads. Raid0 will help considerably for working with large sequencial files such as .VOB (DVD movie files - 1 Gig in size, Blu-ray movie files - up to 40 gigs in size, and large spread system files - NOT normally placed on a small SSD.
Drawbacks out weigh advantages.
