I've owned 17 Seagate ST12000NM001G (12TB SATA) drives over the last 24mos in a big raidz3 pool. My personal stats, grouping by the first 3-4 SN characters: - 5/8 ZLW2s failed - 1/4 ZL2s - 1/2 ZS80 - 0/2 ZTN - 0/1 ZLW0 All drives were refurbs. Two from the Seagate eBay store, all others from ServerPartDeals. 7/15 of the drives I purchases from ServerPartDeals have failed, at least four of those failures have been within 6 weeks of installation.

I originally used the Backblaze when selecting the drive I'd build my storage pool around. Every time the updated stats pop up in my inbox, I check out the table and double-check that my drives are in fact the 001Gs.. the drives that Backblaze reports has having 0.99% AFR.. I guess the lesson is that YMMV.

"All drives were refurbs."

refurbs have terrible reliability... They offer 5 year warranties, yet the replacements they send back have terrible quality......

I think impact can have a big influence on mechanical hard drive longevity, so it could be that the way the ServerPartDeals drives were sourced, handled or shipped compromised them.

Yeah, I don't think that Backblaze are buying refurbs...
