You have Sandforce based drives, which tend to respond well without TRIM. If you -really- need the transfer speeds of 2xSandforce 2, then RAID-0 without TRIM is still a viable option, especially if it isn't a permanent one. If not, then as said above, just use one drive for your OS now, and split stuff between them.
