I am smarting up my home with lots of ZigBee thingies and decided to add a ZigBee smart monitor to my selfhost setup.

Its a desktop box with a core i7 9th gen, 48gb ram, no monitor.

I used to have 4xSSD 4TB + 2xHDD 6TB. Three RAID1 for a total of 4+4+6=14Tbs.

Power was sitting at 50W.

I restructured my storage: 1 RAID5 with the 4 SSDs (12tb) and removed the 2 HDDs.

Power went down to 38W!

I am amazed.

In the future will run just 1 hdd for storing backups and keep it spinned down 99% of the time.

PS: the above wattage is during transcoding, so with high CPU and disk usage…

    wasting stuff just because it’s cheap is how we got here

    Not really, at least if we’re talking about electricity use.

    We got here by expanding our standard of living. Most residential electricity use is heating, cooling, and other major appliances, and we’re not going to make up for that by cutting a few watts here and there.

    Don’t get me wrong, I’m absolutely in favor of small wins, but it’s important to not miss the forest for the trees. For example, don’t throw out good hardware just to save a few watts. If your goal is to help with climate change, there are much better ways to spend your time than cutting a few watts here and there.
