"Set-top box" = Power hog? - TiVo could fix this with software

    Most upgrades are using "green drives" which must help at least somewhat on power consumption.

    When I measured the Premier, it drew 20W, or 175 kWh/year. When I measured our fridge it averaged 47W, 409kWh/year. The fridge is a few years old (from about 04 or so) and wasn't the most efficient one available at the time.

    Turning off the video output is a big deal. Don't dismiss it. It also probably (can't really check this) means the whole video decoding pathway is turned off, including the read of the playback stream from the disk.

    But yes -- it also keeps the cursed Emergency Alert System from messing up your recordings. (That's on a Series 3 or 4. On a Series 2, it allows RF passthrough.)

    Years ago, Dish's first "in-house" generation of DVR's (after the co-branded Microsoft DishPlayer 7100 of 1999) back in 2001 with the 50X series, the HDD's were constantly spinning. At that time HDD's were failing to often, so Dish set it to spin down when the DVR was in stand by resulting in those old HDD's lasting longer.

    Today Dish DVR's HDD's do constantly spin, but when in standby, the cease to write (or record as TiVo does in stand by). This probably extends the life of the HDD as a constantly spinning HDD can last several years. However, it may be a matter of patents to achieve this well, and TiVo opts to just let the machine write and write and forever write until it dies.

    Or it may be a philosophy of TiVo's or it may be a matter of the software in general that may require or work better with never ceasing writing to the disk. I think it has more to do with patents and fear of infringing in having the HDD's cease writing in stand by.

    I wonder why it is so low. All my Premieres draw between 24 and 26 watts. measured with Kill-o-watt meters and also from UPSs.

    But it's not really the old 'standby' mode...
    It doesn't appear to. It used to actually stop the live buffer (and the HDD?). That's what I meant by "bring back standby mode" . . .

    Add a USB flash option or SD card option and I would agree. Too many (including those on here) would ***** about the extra $10 in costs :)
    As a bonus, if I use a bigger SD card/flash stick, can I get longer live buffers?

    Has that standby mode been available in a box Since the S3 models came out? It's been almost five years since that was released.

    This assumes flash can handle continuous writing and rewriting of data, and that the write performance is good enough to handle the sustained data rate. I wouldn't assume either to those to be true (especially when talking about very cheap USB flash sticks) without doing some research. While flash memory is very fast, what people are looking at is typically read performance.

    Someone in this forum did replace his HD with an SSD, but I think he had to go back to the HD for some reason.
