Please do not sell used enterprise hard drives, especially if you got them from your empoyer.
This is how those emberrasing company secrets get leaked and we can’t have that can we? :)
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.
Sell them and buy low budget low power consumption disks that would fit my purpose.
Enterprise-grade usually has enterprise-grade power consumption. From the power saving alone you can buy nice stuff.
solid advice.

Then those disks should have been wiped at the company before they were allowed to leave the building.

Something to think about, at least

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