Could you please elaborate on that? You mean they're different from the ones that caused all the problems with clicking and freezing last year?
Beause if they're not,I wouldn't feel comfortable using them. Regardless of the fix Apple released.
It is not really something apple did, I believe Seagate redid something due to the high rate of failure on their drives; but none of my friends in the galleria store can confirm that they have the 2nd gen 500gb 7200rpm seagate drives inside since Apple bought so many of the 1st gen.
I still say get 5400rpm standard drive and upgrade on your own to Hitachi's
Start up on most application is 1-2 bounces after first start
aperture opens in about 4-6 it seems if that helps put it into perspective for hdd 7200 hitachi
