I buy old SAS/SATA drives that have lots of hours on them. They tend to look like this: https://pastebin.com/raw/E39HuK59 https://pastebin.com/raw/E39HuK59 Ru

Run SMART, check the stats, make sure the grown defect list is 0, make sure it's never been over-temp, run a SMART long test, run bad blocks, run another SMART long test. If it passes all those I'd be fine continuing to use it.
The HUH728080ALE600 drives in that server[1] idle at 5.1 watts[2], so it's 184 watts just on the drives. I'm guessing at idle the server runs around 300 watts. Which is not great, but it's not terrible. I pay ~ $1/watt/year in NC, so running that server 24x7 would cost me $300 annually.
If it were me I'd disconnect at least half the drives to keep as spares.

Lots of techs preferred hot spares not just for immediate availability for the rebuild, but just because the spin-up was just as likely to kill the drive as other failure options. With hot-spares, you could rotate the drives by migrating data around like the old farmers partitioning their fields to let sections rest.
- icedchai 4y agoI use HGST / old Hitachi drives in most of my servers, typically either 2 TB or 3 TB, though I do have some older 1 TBs still kicking (over 10 years, running 24x7.) In all the years, I've only had 1 fail. I just checked and one of them has over 91000 hours!
