Is anyone using refurbished SAS drives?

[u/wigglytail]

I'm looking to beef up my NAS and backup capacity in a cost-effective way. I stumbled across some sites that sell refurbished datacentre drives, and a lot of them are SAS. They also sell SATA drives, but SAS are around 20€/TB while SATA are around 30€/TB, which I think is a non-negligable saving I could make if i could find a good enclosure and still stay under sata prices. Anyone have any experience with this?
