hdd for vu duo. help please.

[bokkie]

I have a 7200 1 tb hitachi deskstar. I've been advised that a 5400 rpm hdd is better. Should i change it? Will it not work properly?
Why is 5400 rpm better? Is it because of heat generation, power consumption.......
Don't really want to change it if i can avoid it.
Can anyone recommend a hard drive?
Thx guys

5400rpm will be quiter, i installed a 1tb 2.5inch 5200rpm drive in mine and its totally silent and works very well, used to have a 7200rpm 3.5inch drive inside , i would hear it at night, so decided to get a 2.5 inch drive
