If you were to suddenly come into possession of 12+ enterprise-grade SAS hard drives, how would you go about incorporating them into your homelab?

Pretend your only other hardware is a repurposed HP Prodesk and your budget is bottom-barrel

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.
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 per year * $0.18/kWh = $5.84 per year in power usage * 12 disks in an array = $70.02 per year *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, large and repeated writes and reads, ect). The power consumption for that is 5.5W, which is a lot closer to the Ultrastar* WD Ultrastar: - 7W*24 Hours/day*365 days/year = 61kWh per year * $0.18/kWh = $11.05 per year in power usage * 12 disks in an array = $132.6 per yearSeems 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.
Sometimes a day just FEELS like it's 48 hours long.
Lol, thanks

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.
that's all true. I'm anxious to get them open and see what they test at; it really seems like some of them are unused, but that could just be because they were refurbished and re-packaged. I'm really curious what the spin times are.
solid advice.
Please do not sell used enterprise hard drives, especially if you got them from your employer. This is how those emberrasing company secrets get leaked and we can't have that can we? :)
Then those disks should have been wiped at the company before they were allowed to leave the building.
Yes!
Yes, they should have been wiped. (and then they should have been fed into a blender if i had my way.) :)
