Hello!
Anyone know if there is any noticeable difference between a WD2500BEVT (5400 rpm 2.5" HDD) and a WD2500BJKT (7200 rpm 2.5" HDD) in terms of noise and heat?

Regards

7200 rpm hard drives are the way to go. my laptop has a 2.5" one and with the fan going i don't hear the noise at all. as for the heat difference, right now the ambient temp. is about 68 degrees F and the hard drive is 40 degrees C. when it was like 80dF degrees in the summer the hard drive would usually be 47dC. (the max operating temp. is 55dC.) i don't know why they don't put 7200 rpm drives in all mid-full size laptops. my guess is that people think the more disk space the better the hard drive and 7200 rpm drives do use more juice.

And the power consumption is also almost identical...
