I've got a set of the Western Digital 'Green' drives coming in
tomorrow (whoops...today now):
8.5 Watts - only 5400 RPM though (so I'm expecting to cache
aggressively). I'm trying to build a quiet, powerful 1U server so
every Watt counts in keeping the fans slow (quiet). We'll see,
Thanks for the feedback on the Green drives. Good to hear!

FYI, from what I've read, some of those devices violate the USB

I'd recommend buying from a
vendor with an easy returns policy, just in case.
I agree with Ben's warning, and perhaps I was not clear enough in my
write-up that this was more or less a study and try scenario for those

Transformer-based wall-wart efficiency: Typically 23 - 28 %
Switching wall-wart efficiency: Typically 80 - 90%
For a device that will be on 24/7, a switching supply pays for itself in
less than a year in New England.

The Kill-a-watt loses all data on power loss; the other does not. Also, the
displayed resolution on the kill-a-watt is a bit coarse for things like wall
warts, though it apparently has higher internal resolution. I found it
necessary to run a wall wart off of one for a full 48 hours to get

PS: For 220, you can measure the two live legs using 2 separate meters.
But in general, things like dryers and ranges will have the same
readings for both legs.

All I know is that I have never, ever had quite the sensation of burying
my nose in sheets and towels dried in a clothes drier as I had with
clothes right off the clothes line.
The lack of that fresh, clean, natural scent is what clothes driers cost

It doesn't have the space that you are looking for, but with a new drive
and some working you could get it to whatever size you want. Due to the
low profile, it only takes laptop hard drives.
