This drive has just been released, it uses 2 * 320gb platters and gives about 95mb/sec avg read, its the same speed as the 1TB samsung f1, it has less cache than it but has 1 less platter so less movement is needed so the speed is the same.
VERY fast drive, very quiet:) The western digital 640gb isnt as good, it has about same read speed but slower access times and noisier and more expensive. This is the new best bang for buck drive, atleast until the 320gb version hits the uk shores.

This will beat the 150GB raptor in the vast majority of tests btw, only slower in access times and 1 or 2 tests. The 300GB Velociraptor is faster than this in virtually all tests but is £193 and noisy and less than half the capacity.
