I know basically any 2.5" hdd should fit.
However what im worried about is battery life decreasing..
The current hdd is 5400rpm, so if i got a 500gb with 7200rpm, would this have a significant or even a minimal reduction to battery life?
and if anyone has any first hand experience could you please share it? 
Thanks alot |
deterioration of battery life is inevitable... However, the decrease might be reduced if u get one with power efficiency...
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.
