SSD will do fantiastic in RAID. ive got my 64GB SSD, and I cant wait to get another and raid them. SSDs scale performance in raid much better than regular HDDs

traditionally with RAID if you have 1 HDD itll do Z amount of performance. adding a 2nd however does not give you Z x2 performance. Some applications/games will get close, sometimes you may only get 1.1x Z performance. but with SSD drives, they will get you close to 2x Z performance. Google Battleship Mtron and you'll see what i mean. they RAID 9 SSD drives together and max out the capability of the controllers (not the SSDs) a few times.
