Are they worth considering or only worth it at certain price points?
Depends on the warranty.
Depends on how much you value your data and how much redundancy you have. I bought a 20tb “manufacturer certified” drive from SPD the other day and it tests fine, but I’m not going to put valuable data on it. Maybe if this drive outlives my shucked easy stores I’ll buy more. But for now my main raid array is new drives only that I’ve throughly tested before installing.
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.
RAID is your friend. If you can’t afford to lose one, you might have a bad time (applies to all drives anyway). Manufacturer refurbs are your best bet.
Purchased 5 renewed drives from amazon, 10 months in 3 have had to be replaced because of escalating bad sectors, all three were outside of the refurbish guarantee… one by only a week. Save your money and go with the new drives.
I’ve not heard any out-and-out horror stories, but I’ve got no first hand experience.
I’m planning on picking up 3x manufacturer recertified 18TB drives from SPD when money allows, but for now I’m running 6x ancient (minimum 4 years old) 3TB WD Reds in RAID 6. I keep a close eye on SMART stats, and can pick up a replacement within a day if something starts to look iffy. My plan is to treat the 18TBs the same; hard drives are consumables, they wear out over time, and you have to be ready to replace them when they do
Sounds like the term used by Amazon? I picked up eight 18TB “renewed” drives that have been in constant use for over a year now under a ZFS filesystem. Not a single error yet and the pool is about half full. At the time I bought them, they were about $100 cheaper (each) than brand new drives so that saved me quite a bit of money, but they were also a fairly new line of drives so there couldn’t have been much previous use on them anyway.
I’ve been using renewed (refurbished) 8TB drives off of Ebay - SAS 8TB for $50-60 each. Not a single failure in over a year on the dozen or so drives I’m running right now. I’m running unRAID with a combination of unRAID’s native array drives (for media and “disposable” stuff) in a dual parity config, and ZFS (with snapshots replicated to a live backup on a secondary server) for important personal stuff (and backed-up off-site a few times a year).
Even if something were to perish, I have enough spares to just chuck one in and let it resilver without worrying at all. I’m content with this as a homelabber and when I’m not supplying critical service for a business, etc.
