2x240gb ssd in raid 0, or 1x512gb?

hi overclockers,

i'm about to start my first build, and could use some advice on a SSD. I am stuck whether as to go with 2 240GB corsair force 3 SSD's, or one 512GB Crucial M4 SSD. I am using this as my main drive for the OS, so if I use two smaller drives I will combine them with RAID 0. which combination will give me better performance? I know that RAID 0 halves reliability, but these are still SSD's so i'm ahead of the game anyway than if i were to use a HDD. (i am using an HDD as backup/storage)

the crucial M4 is about $130 more expensive. if i get the two SSD's i will put the extra cash into a better monitor, which i am inclined to do atm.

i will be using this build for gaming, multitasking and programming (Pthon). the rest of the build is an i7 3770k CPU (when released), an ASUS P8Z77-V mobo, a nvidia GTX 680 GPU, 16GB corsair vengence RAM (1866Mhz) and a H60 corsair cooler.

also, on this system what will the bottleneck be? any other comments on those parts?

thanks

Hands down 1 512GB. Unless you work with large files a lot, R0 isnt worth the chance of the array crapping out (much less a drive).

No other comments. Looks solid to me (though you didnt mention a PSU).

1+ if you willing to spend $500+ on SSDs go for the 512gb!

thanks for the speedy reply. for the psu i'm using a corsair enthusiast series 750W.

Depends on what you're gonna use em for. If you need tons of bandiwdth the RAID 0 might be a good choice. But if it's not too important then stick with the single 512. Your seek/access times are gonna be insanely low, so unless you're working with very large, sequential files get the single drive as its simpler and more reliable.
