I have 2x Samsung 830 64gb in raid 0. In crystal diskmark read speed is like 1000 mbps and write speed is like 350 mbps. Slight overkill? Yes. But its wicked fast and windows is so responsive. Will never go back to using a HDD as operating system drive. Even my laptop has a 40gb msata intel ssd for the os and a 320gb hdd for data.
Also I can post some screens of my samsung 830 raid 0 tomorrow morning if you want.
