Upgrading Notebook Hard Drive, Power Considerations?

Hey,

I'd like to upgrade my current notebook's hard drive, a really slow 4200 RPM hdd. In any case I'd like to replace it with a WD1600BEKT, a 2.5" notebook hdd with 7200 rpm specs.

But I'm worried, the notebook is pretty recent, around 2008 - but since 4200 rpm was the default hdd, can the notebook support a 7200 rpm upgrade? Would I need to worry about power requirements? Or does the fact that its a SATA drive make it universally compatible in power requirements, despite the RPM's?

  1. you should be fine with the upgrade. you might see a slight loss in power usage, but it will be small (almost insignificant IMO)
