The 3tb capacity drives- nearly all of the various models and brands- had huge issues- but these were among the worst drives I’ve ever seen. 2011 was a rough year- at the time I was helping fill in building white boxes and we used to order hard drives by the pallet from our VAR- the flooding in Thailand really screwed with our supply line for hard drives and jacked the prices wayyy up. I remember the day we opened the first full case of these (~20 drives iirc) and only 4 passed initial burn in testing. Well over half didn’t even survive the initial clone. It was bad enough that our sales rep drove over with a UHAUL and a pallet of WD replacements later that week. Seagate also dropped the typical 3 year warranty to only 1 year about that same time. Needless to say we switched to WD and didn’t look back. The big joke at the time was they had white labeled a new ‘death star’ hard drive (IBM/Hitachi Deskstar drives were notoriously bad) that had more storage than the old ones. At one point there was a class action lawsuit or two but I don’t think they went anywhere. Huge mess. I will say the ones that survived burn in may have been fine long term, but we just did a full blanket swap with WD drives as it wasn’t worth the risk.
