I am trying to build a supper low watt system. I will be needing at least 500gb of storage and will use 2 drives in a mirrored raid. The WD Caviar Green has a 32 cash 7200 rpm. it uses: Read/write 5.4 and idle 2.8. A laptop hard drive (WD Scorpio Blue) only has an 8mb cash and a 5400 rpm hard drive. It uses: Read/write 3.5 and idle .85. All it will be used for is downloading torrents and streaming video over the lan. Is the small cash and slow rpm really going to be a huge deal? I know it will be slower, but since the computer has an atom cpu and is not real powerful anyway would the laptop drive work? The laptop drive uses less power working then the desktop one does idling.

The slowest hdd will be a lot faster then your download speed. So use whichever suits your needs.

I find 5400RPM drives to be nearly unbearable. Disk-intensive apps literally run 5-6 times faster on my desktop system (1TB, 7200RPM, 32MB cache) than they do on my laptop (160GB, 5400RPM, 8MB cache).

Hard drives don't consume much power anymore; many laptops come with 7200rpm drives. Do yourself a favour and forget the 5400.
