Pretty much what I expected. My PVR-250s suck about 10-11 watts so I'm
not surprised to see the PVR-350 suck a bit more. I definitely would
be interested in any power measurements from a PVR-150 and PVR-500.

Notebook drives idle at ~1 watt, so if you're serious about power
that's the type of drive to use.

It definitely works pretty well. I noticed that NewEgg started
carrying them recently as well.

BTW, do you have any idea how efficient your PSU is? For a system with
such a low power draw, something like a PicoPSU would likely be at
least 20% more efficient than stock so could save you another 5w or
so. :-)

the list but just sent it to me
