It does not add up. How does goHardDrive make money with a 5 year reseller warranty on a product most likely missing its most reliable years. Even if they get them as free e-waste you're counting on them existing for years to come. They also wipe the SMART history of some of the drives. And they lied to the OP saying some would be new. Those facts alone are scummy enough to put the their "warranty" in quotes.
I think most people - except those that really like Hitachi - are better off buying a new 12TB for $80 more.
Are you kidding me? You're saying IF a company gets a product for free (e-waste), spends some labor to clean it up, and gets to sell it for $100, that they can't make a net profit?
Some large corps actually have an explicit policy to physically destroy their used data center hard drives. It's wild but they use some kind of industrial shredder that can ingest 3.5" HDDs. Although it's understandable why they can't risk the data falling into the wrong hands, this is incredibly wasteful behavior.
So instead of paying someone to shred your drives, you can sell them off to goHardDrive for very cheap. Now obviously you can't just trust anyone to take away your used drives but perhaps with an audited system and reputable firm, you'd do it.* I'm not sure that it even makes economic sense for the company getting rid of the data center drives, but it's a win for consumers and the reseller.
Also it's not $80 more, but $110 per drive. If I was in
@Shmee 's shoes and could save $500 on a personal storage array, I'd do it.
Finally, the $200 IronWolf drives you're referring to are a good consumer NAS drive, roughly equivalent to WDC's Red drives. These have been described as desktop class drives with firmware tweaks targeting SOHO NAS usage. In other words, they aren't data center class (as reflected by the 3yr warranty). I don't see any mention of TLER, so you shouldn't even use them with a hardware RAID controller. IronWolf Pro, Red Pro, and data center HDD are designed for heavier workloads, and cost even more.
* Perhaps all the data was encrypted and all you had to do was toss away the keys.
I went ahead and ordered 4 of them from Newegg at $85 a drive. I also ordered a new Platinum PSU and a SAS backplane/HDD cage. The SAS cable already came from Amazon.
Just out of curiosity, please post the Power on Hours and if all the drives are in good condition when you get to evaluate them.
Current price is back to $90 where it's been for a while (with the exception of a few days at $85).
If you're like me and discard a failed drive after destroying the platters rather than RMA'ing it, I only need it to work & not be DOA really. The warranty is a feel good bit, unless these were getting hammered most of these enterprise drives spent a lot of time parked. Spending 2x the price to get a "new" drive is a little silly for me, better to invest that $80 into a second drive and backup my data. Or hold that money for a few years and buy a 3x capacity drive with the difference at that point.
Exactly, why spend double if you don't have to?
Backblaze has tons of data on the failure rates of various hard drives (although IIRC they tend to buy mostly consumer class drives), so you can make a somewhat informed decision and proceed accordingly.
