Few q's because although I've read loads , I think my brain is now fried with too much info...

- Is TRIM still a necessity? Or can we manager without?
- And if TRIM isn't needed, what can I expect from 2x SSD's in RAID 0 on my CHIV on board SATA ports?
- Looking at the Crucial M4 or the Corsair Force 3 but heard there were issues with the new Corsair's? (have these been resolved?)

Kinda wish I'd pre-ordered the M$ 512Gb since they were dirt cheap (~£500 as apposed to £600!) but still have the opportunity.
