Low-powerered Ethernet Hard Drive?

WotPeed asks: "The company I work for builds extremely sensitive electric and magnetic field sensors. The project I'm just starting needs to use a hard drive to store the digitized data for long-term measurements (no more than 20GB). Unfortunately the hard drive has to be external to the sensor because it generates too much magnetic interference (hard drive needs to be at least 20 feet away). I'm therefore building an ethernet link into the sensor so that it can connect to a remote hard drive. Wireless is an option for a later revision but we're going with wired ethernet at first to keep things simple. There are plenty of network attached storage devices out there but they all assume they will be used in an office environment, and therefore consume a LOT of power. I'm looking for an ethernet hard drive that consumes less than 10W (this system will be used outdoors and runs on 12V batteries). Does Slashdot have any suggestions before I roll my own? I don't need any of the fancy features found in most NAS solutions...I just want a hard drive I can FTP to."

Actually the Ipod uses a non-cheap, not-so-mass-produced 1.8" hard drive - that's why it's so small. Apart from this, yes, I fully agree.
I recently replaced the hdd in my laptop with a 40GB one, which eats 2.2 Watt and cost me less than 100 Euro.

How you're gonna hook it up a fastethernet without a PC in between is another story :-)
(but I think such interfaces do exist).

Another option could be a Firewire or USB2 enclosure - they allow fairly long cables - up to 20 metres (sorry no body parts used for measurements on this side of the pond) for firewire on sale at the 1394 store. Linux and Windows have no problem using them.
