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…
Sure it’s 100kWh in a year, so it’s a few bucks per month saved. But in reality it’s likely even less than half that saved, because the majority of the time it’s probably not under transcoding loads.
