any serial ata 2.5" drive should work fine. it's up to you what speed (rpm) you want and size. and brand/model.
you can google "laptop drive reviews" and can find some good reviews. newegg has pretty decent prices.
i like my seagate 120gig 5400.2 drive in my black macbook. very easy to install (just need a torx 8 screw driver).
