This is a great observation, and it made me do some math:
If my point of comparison is something like a seagate ironwolf 4T vs a WD Ultrastar 4T:
Seagate Ironwolf:
-3.7W*24 Hours/day*365 days/year=32kWh peryear* $0.18/kWh = $5.84peryearin power usage *12 disks in an array= $70.02peryear*Edit: Looking at this closer, a more reasonable comparison would be an ironwolf PRO disk, since this is a NAS use-case (24-7 run time, largeand repeated writes andreads, ect). The power consumption for that is5.5W, which is a lot closer to the Ultrastar*
WD Ultrastar:
-7W*24 Hours/day*365 days/year=61kWh peryear* $0.18/kWh = $11.05peryearin power usage *12 disks in an array= $132.6peryear
Seems like i’d save maybe $70 per year. I feel like that difference might even be justifiable if the enterprise drives are half as likely to fail (seagate ironwolf has an AFR of 0.87%, WD Ultrastar is 0.44%).

Something to think about, at least
635 days is a fucking long year.
Lol, thanks
Sometimes a day just FEELS like it’s 48 hours long.
2020 mood math.
