Thats not out of hand, $313 for 16G.

Of course these are nand flash drives I can get this for $181:

Here is the Raptor X for comparison:

Hard Drive
Form Factor 3.5" x 1/3H
Capacity 150 GB
Interface Type Serial ATA-150
Buffer Size 16 MB
Performance
Drive Transfer Rate 150 MBps (external) / 102 MBps (internal)
Seek Time 4.6 ms (average) / 10.2 ms (max)
Track-to-track Seek Time 0.4 ms
Average Latency 2.99 ms
Spindle Speed 10000 rpm


If your raptor is defrag and its only doing the .4ms track-track seek and not loading a ton of tiny files it would seem its 150MB sequetial read is faster then the SSD 120MB sequetial read. And the raptor write times are almost 2X as fast.
