I'm running several used ("renewed") enterprise SAS HDDs and enterprise SATA SSDs. They've been solid so far.
The HDDs came with about 30k hours each which is not bad at all, and the SSDs only had around 100 TB written out of the total 6.2 PB rating.
I'm not sure I would do used with standard consumer HDDs, they typically don't last as long and are likely abused a lot more in a desktop PC vs a datacenter server.
As always have proper backups in place, all drives fail eventually no matter where you buy them.
