Windows 7 is really good at handling SSDs, it been optimised for it.
I personally wouldnt run raid 0 though, as effectively you have doubled your chances of failure, you will get the benefits of double speed write, but would sooner be more secure and run Raid 1 (If you are using 2 disks) still get double read, only same write though.
I was thinking about the cons of raid0 like disc failure but if those discs are only going to be running the os and progs, any important files will be stored on a different old sckool disk so if it does fail then nothing important would be lost.
Im not sure about SSD but Ive never had a HDD fail on me so would be daft lossing out on a performance gain just because of a slight chance of failure.
Ive heard somewhere that you shouldnt use SSD drives for pagefile/virtual memory, any ideas?
