Basically, nb hdd spinning at 7200rpm has 2 versions. One with energy efficient technology that increases the batt consumption by 0.5 percent and one without such technology. However, so far i couldn't find those with energy efficiency technology off the shelf.

Another thing to note other than the rpm of the hdd, u might also want to know if the sata chipset support 3ghz transfer rate.

if it doesnt, u can still upgrade the hdd. It ll just run at 1.5ghz.

The performance will be marginally better than ur current hdd becos the 500gb hdd comes with a bigger16mb cache and faster rpm.
The new MBs support SATA2 transfer speed.
