SSD RAID 0 TRIM Confirmed @ RWLabs
 

Around the time Intel released their 520 Series of SSDs based on the SandForce SF-2281 FPU a new set of drivers started going around that claimed RAID 0 TRIM support. While the early 11.5 Series drivers claimed this massive feat was possible, it took a new, very special RAID Option ROM to get RAID 0 TRIM functional. Around a week and a half ago a new RAID OROM started tipping up and with it claims of working RAID 0 TRIM were rampant again....Only this time it really worked.
