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…

    The hdd spin on once every night for backup, then off after a bit by the timeout.

    That should not be a critical issue.

      Yeah, most PCs get turned on and off like once per day. For example at most offices or at home. That’s perfectly within normal use.
