Pros: Drive is described accurately. Makes same noise and has same power consumption as the 5400rpm drives. Definite speed increase. No apparent extra vibrations or heat. Excellent drive. Works flawlessly so far on Macbook Pro 13" mid 2009.

Cons: Had to get a torx screw driver to install the mac mounting screws, but thats not WD's fault.

Overall Review: Great drive and great price with decent size. No other drive has all the specs.
