Look at that Random Access time difference though, that's pretty substantial. The Raptor is nearly 1/2 the delay. If I remember correctly from your graphs, it was 9 ms versus 16 ms. Btw, did you ever test sustained speeds or just burst?
Ya the 36GB Raptor is the worst of them all but still good. But Sccr is right, unless you do a lot of heavy file transfer and/or audio and video editing, access times are a better judge of performance. And, its cooler to say you have a meat-eating dinosaur in your PC.
For what its worth, Tom's Hardware did a comparison of the new Raptor-X vs. 2 7400 RAID 0 drives and concluded one Raptor-X is the better option. Here is the link if you are interested. The only thing that cited the 7400rpm RAID 0 was better at was pure throughput.
