750GB 7200RPM Solid State?
Didn't realise solid state span round?
Don't get fooled by the marketing spiel of the Momentus XT Hybrid (assuming this is what you mean), they aren't anywhere near the performance of an SSD, infact I could barely see a difference between a 500GB Momentus and a 500GB Momentus XT.
I've got a 500GB Momentus XT for Steam games that aren't on my SSD, and I'm reasonably impressed with it for that function... I expect it'd do ok in a laptop... but a proper SSD would be miles better.
