[hardware] Used SAS drives? (feddit.de)

I just browsed eBay a bit and saw that older, used SAS drives can be had pretty cheap - 30€ for 4TB, but of course rather old drives, sometimes 10 years old.

Now, I wouldn't expect ultra reliable, ultra fast, super cheap drives here. But this offer seems compelling, even buying a spare drive for higher redundancy would still be pretty cheap.

Question is: am I too optimistic here? Are these drives bound to fail within 3 months?

SAS drives are cheaper because the market is smaller. You need SAS hardware to use them, but SATA drives can go basically anywhere.

Hopefully the seller gives some idea of the condition. Usually the ones I've bought have been anywhere between 10k and 40k power-on hours. Much more than that, if they were really cheap, I'd just buy spares.

The other big health factor is start-stop counts. Server drives shouldn't have too many of those. If that number is really high, I'd be concerned about how the drive was used.
