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*635 days/year=32kWh peryear* $0.18/kWh = $5.84peryearin power usage *12 disks in an array= $70.02peryear
WD Ultrastar:
-7W*24 Hours/day*635 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%).
In defence, the power prizing here is a tad different, €0.45/KWh was the prize here. Also, when those disks are given away, they are usually smaller then the current standard and less efficient. On the other hand, those enterprise grade disks generate some heat, saving on the heating bill.

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.
