7200rpm vs 5400rpm 2.5"

7200rpm vs 5400rpm 2.5"
In a laptop 2.5" is a 7200 rpm drive going to be much hotter and drain more power than a 5400 rpm drive? A friend's laptop hard drive just died and he wants a new one but I don't know whether its better to get a 7200rpm or a 5400 rpm. I know its much faster, but does it comes at the cost of heat, noise, and battery.

If your friend can swing it, an SSD would be faster, use less power, and run cooler.

Heat shouldn't a problem, same with noise (usually the CPU cooling fan will be louder), as for power consumption, it will be slightly higher when you compare similar hard drives, but it's hard to say without knowing which specific hard drives (the one he currently has vs what you're considering) you're talking about.

Have you considered an hybrid hard drive (Hard drive with flash memory) or a SSD? Either one of these will offer significantly higher performance, without the additional noise/heat/power consumption from a 7,200rpm hard drive.

Well his first one was probably a 5400 rpm or 5900 rpm, the usual standard you get on a budget laptop nowadays. But SSD is probably too expensive and by a hybrid hard drive like the Seagate Momentus XT?

Hybrid hard drives actually have slightly higher power consumption than normal hard drives, considering that they have the hard drive power consumption as well as the NAND power consumption.
