take a look at this review, and where the raptor 600gb compares to various SSDs:http://www.anandtech.com/bench/SSD/65
for some benchmarks, it isn't even close. For a few, the raptor beats some of the slower SSDs. Of course, you have quite a bit more room on the raptors than the SSD, and for video that could be an issue.
Raptors in raid 0 should be very nice (no redundancy, make sure you back up elsewhere though)
