    The WD20EURS 2TB drive is available at Buy.com for $115 now. It looks like it's the newest generation of AV-GP drives. Looking through the specs, it has the lowest power requirements currently:

    WD20EURS: Read/Write @ 4.5W, Idle @ 4.0W
    WD20EVDS: Read/Write @ 5.9W, Idle @ 4.9W
    WD20EARS: Read/Write @ 6.0W, Idle @ 3.7W
    WD20EADS: Read/Write @ 6.0W, Idle @ 3.7W

    I added the Idle, but I think Read/Write is the most useful since the Tivo is constantly reading and writing, right? Anyone know how we might be able to translate the numbers into a calculation of the expected power savings over a month or a year? I found an old thread that suggests multiplying the wattage x .72 x your electricity rate, so at $0.18/kWh, I guess the EURS is worth about $0.20/month versus the EARS or EADS?

    The Western Digital product page where I found the data is at:

    Click through to the particular model and switch to the "Specifications"

    Thanks for the post. I came across this in investigating an upgrade strategy for my yet to be shipped premiere. You saved me some time spent on my own research! ;)

    Is a savings of $0.20/month even worth talking about?
