    When I first powered on my Roamio Pro I saw the wattage meter hit around 26 watts initially and then dropped down. When I looked after it finished booting it was around 16 watts.

    I'm making a connection to TiVo right now and while downloading it's fluctuating between 20.5 watts and 21 watts.

    Good to know. Any numbers while using Stream to iOS device?

    I had initiated a "Clear and Delete" last night. This morning it was drawing around 21 watts, just sitting there for setup, before I pulled the plug. I'll be starting over again tonight with a new cable card.

    At least I know now I can connect to the Roamio with my Minis. Now I just need to transfer all my SPs after I get the new cable card in.

    Everytime I look at the meter on my Roamio Pro it's been drawing around 21 watts. So I guess when buffering all six tuners it's around 21 watts. And when not it's around 16 watts.

    It's always buffering all 6 channels. Unless you force a tuner to a channel you don't get. What if you put it into standby? Does that have a noticeable effect on power consumption?
    Is there any way to turn off the internal Stream? If so turn that off and see if it effects the usage?

    I didn't notice any options for the Stream part of it. Plus I can't even test it since I don't have any Apple products.

    I just tried standby. It took it down to around 20 watts( I saw it as low as 19.8 watts). So it reduced the wattage used by 1 to 1.5 watts. Since when not in standby it does fluctuate above 21 watts.

    I wonder how much the Roamio Basic would use powered direct from 12VDC.

    Anybody got a Fluke? :)

    So I'm wondering if the power savings (Roughly $10/$15) a year, is outweighed by the potential damage to the TiVo. All of those hard power cuts aren't great for the drive. Ever had any problems? How long have you been doing that for? Just wondering out loud...

    Modern drives auto-park when the power is cut. They use the momentum of the spinning platters to park the head, so there is no damage to a drive by simply cutting it's power.

    That being said I personally do the opposite. I have my TiVos connected to UPSes and never cut their power unless they have a problem that requires a hard reboot or we have a power outage long enough to drain the UPS batteries.

    Good point on auto park. But still cutting the power from a device designed to operate 24x7 clearly puts a little extra strain on it. Just not sure why anybody would do that to save so little money each year.

    I do the same thing as you and have my TiVo on a UPS to ensure its always running.

    That's an argument as old as the HDD itself. Some people argue that leaving it spinning 24/7 shortens the life while others say that the strain of constantly spinning up from a stop shortens the life. Studies have been done that favor both positions, but usually the margin of error is about the same as the difference.

    That being said, I agree that it doesn't seem worth the risk for such a minor power savings.

    I run mine all the time and they are connected to to a ups like all my electronics. But I can see why someone might shut it off for half the day. The savings add up from multiple devices. A dollar here and a dollar there add up in the savings on the electric bill each month.

    I'm just not that frugal.

    Yes sir it is. One day TiVo's will use SSD's and that won't matter anymore. I'd also worry about the power supply from the daily shutoffs.

    Been doing for the last 3 years, without any problems, nothing every corrupted that I saw, the TiVo may fix the files itself as people have the power cut to TiVos all the time in normal use, power loss, a hard re-boot, moving the TiVo, etc. I do give it 2.5 hours after 2AM to make sure any software update is atomically put in the TiVo. The last thing TiVo would want is many people having problems after any power interruptions as most TiVo users, not on this forum, do not use a UPS on the TiVo.
    As for the electronics, I turn off my TV, my DVD player, my sound amp. system, and my Computer (to sleep mode), not any problem with modern electronics.
    People have their own hang up on this subject, so do what you feel good about. Long term heat can harm electronics as starting up electronics may, never saw any study on the subject.

    Glad you haven't had any problems. You aren't really turning off those other items just putting them in standby mode, unless your actually unplugging them all. Seems like a lot of efforts with little gain to power cycle the TiVo daily, but hey if it doesn't hurt anything and saves you a couple bucks a year sounds good to me.

    One day I'd love a house with power meters on every outlet I could review from a web console. One day..

    From what I've read about SSDs, they don't seem like a great fit for a device like a DVR. Current SSDs have a limited lifetime due to degradation after many write/erase cycles. That lifetime may be several years, but it will likely always be shorter than magnetic disks. SSDs excel in apps where you are mostly reading. A DVR, OTOH, is always writing the current tuner(s) to a disk buffer, plus any scheduled recordings. Writes will be dominant, wearing out the device more quickly than normal PC usage.

    True today, but in 20 years (or less) may not be a problem for TiVo use.

    Scary thought..in 20 years I will be 85! Hope I still understand and can see and hear what I am watching!

    Seriously though, appreciate the knowledge that is shared and available on the forum. Being a brand new TiVo user it is much needed.

    Thanks,

    Doc

    You are right, an SSD is a poor choice for a DVR. Besides, the main advantage of the SSD is speed, which is not really necessary in a DVR.
