Looking to buy a new laptop hard drive, wanting opinions

[Brushstroke]

I have a Toshiba Satellite laptop that I've been wanting to do a few upgrades to. Number one is the hard drive. It has a 250GB SATA drive in it running at 5400 RPM. I want to get something with double the capacity and at 7200 RPM, 16 MB cache. Pretty basic specs, something that I could get for between $70 and $100. But I'm also looking for the most energy efficient piece of hardware.

So, opinions on the most energy efficient laptop hard drive with these specifications? What brand should I go with? Seagate, Western Digital, Samsung, Hitachi, something else entirely...?

Thanks!

I put this one in my netbook and have been very happy with it. Dense platters, large cache, fast spindle speed. Reads and writes consistently ~100mb/s
