SATA III (HDD) vs Momentus XT (SATA II)

Hi all, n00b to Tom's forums.

I am getting a notebook soon for college and I was wondering if a 500gb SATA III Hard drive or the 500gb Seagate Momentus XT Hybrid (SATA II) would be faster, perform better overall, etc.

Not sure if it depends at all on other computer specs but I was planning on getting a laptop with the i7-2720QM (2.2-3.3GHz), 8gb DDR3 1333MHz RAM, and a nVidia GT 555M 2gb.

Thanks guys.


Edit: Oh and I was figuring the hard drive would be 7200rpm. 750gb wouldn't be bad either but probably 500gb.

And I want to clarify: when I say SATA III, I mean SATA Revision 3.0 (6gb/s) and SATA II is SATA Revision 2.0 (3gb/s).

  1. No physical hard drive can transfer over the rate of an SATA II port, so you don't need one unless you are moving to an SSD (or a big RAID array, but I doubt that you are going to put one in a notebook).

    In theory the Momentus hybrid may have better startup and app load times, but I wouldn't bet too much on it. Try it if it isn't too expensive an upgrade.
