    I know the r/w speed of one drive is 550/500, and two drives w/ raid 0 is 800/800 or something like that.

    If I run two ssd's on this card without Raid, do both drives still get 550/550 r/w each? Or since they share the same card, its lower? Does anyone know?

    Assuming your figures are correct, then it looks like the card bottlenecks at 800MB/s so if your I/O is pushing both drives at the same time (eg. copying a file from one drive to the other), this is the maximum throughput you can expect to get. However, if you're only putting demands on a single drive at any given time, the throughput will be at the drive's limit of 550/500.
