None of the drives were actually completely dead. In fact, in each case, the parameter which caused them to be reported as "FAILED!" was the Spin_Retry_Count, with one of the drives having a raw value of 1441811 when I replaced it.
I suspect that, once spinning, the drives would probably continue to work fine for months (years?) but since they were being reported as having the potential to fail within 24 hours and were all within their return window, I felt it was better to replace them rather than risk a more serious failure.

The listing didn't actually say they were refurbished drives. That was just assumed from the price. Since they came with a card which indicated 5 year warranty (which turned out not to be valid outside the US) I concluded the were actually new and just old stock.
I think I've only ever bought something like 20+ drives over the years, but the only 2 I'd had trouble with before the HGSTs was one Seagate (out of about a dozen over the years) and one unbranded drive which came preinstalled in a microserver I bought. It was only 250Gb so I moved it out and put it in an external enclosure which probably shortened its life!

There is at least one site that uses massive numbers of hard drives (thousands at least) and have been doing so for years.
They collect failures stats for all of those at an individual basis and make the results public. They have been doing that for quite some time.
Lots of detail.
Fun random read. And probably more relevant it you really need to get some real world stats on failure rates.

So, I guess not knowing is driving you crazy. Yeah I know, I'll get my coat. 
StarNamer@work wrote: I'm beginning to think this may have been false economy and I'd have done better sticking with newer Seagate drives despite the price!
Keep in mind, I haven't built a RAID in years. So, my experience is old and crusty, but back in the day Seagates were always known to fail before drives like from WD. I'm sure someone online will get upset and emotional about that, but whatever. Anyway, what time span are you talking here? Assume the warranty was still valid then did all these drive failures happen within a year? If so, that's crazy.
Also assuming prior to this HGST fiasco you didn't have drives failing like popcorn popping in the microwave, which would indicate a problem with your housing... maybe it overheats (which is a big problem), or you're setting your enclosure on top of a large speaker magnet for funzies, etc... Then you might be onto something.
If HGST was acquired by WD in 2012 then it's safe to assume they it was acquired with inventory. Given the fact that we had serious economic trouble in 2007-2008 and inventory can be manufactured a few years before it's actually sold to the customer (depends on the size of the company), or even if manufactured in 2012 maybe they started in 2008 being cheap and continued with it. So, in theory it's possible there was some cheap batches made you were unlucky to get. It's just conjecture though. Either way, might be time to try a different brand.
Side note, Google used to keep a list of which drive brands suck. They go through millions of them and they know. They refused to release that list though as it would effectively put that company out of business... even though in a real free market that can and should happen. Which is to say, the consumer is the last person companies care about these days.

Backblaze isn't shying away from that, and my conclusions seem to match their yearly reports.
RE: HGST...weren't they the ones that had a major flood at their manufacturing plant a decade+ ago, and subsequently had a huge batch of unreliable drives?

Respect.

Dunno. I've been doing cloud everything lately, so me old and crusty with that. Never even heard of HGST until this post. It would explain a lot though.

I think HGST used to be a Hitachi brand, and I've purchased external drives from WD, and the drives inside had an HGST label. Even recent ones, so even though they might no longer promote the HGST brand (at least on the box), WD is clearly still using the name internally...
And I don't think I've had any sort of bad failure rate with the drives I have that I know are HGST.

They were and Hitachi bought that division from IBM earlier. The flooding happened in Thailand if I recall correctly.

2 things:
(a) I see MSN still hasn't lost their habit of spreading their "[N] reasons why XYZ" type of articles over [N+M] pages (where M are just extra ad pages). So make that 19 reasons.
(b) Was there anything in there that was actually unique to men, and could not equally apply to women? Besides, aren't we're all supposed to be gender-fluid now?

Black holes generating enormous power has been around in science fiction for a while (Arthur C. Clark - Imperial Earth (1976)). More recent in the Star Trek Universe with the Romulan D'deridex-class warbird uses an artificial quantum singularity as a power source for its warp propulsion drive.
from the Wikipedia article ( Black hole starship - Wikipedia[^])
" A black hole weighing 606,000 metric tons (6.06 × 108 kg) would have a Schwarzschild radius of 0.9 attometers (0.9 × 10–18 m, or 9 × 10–19 m), a power output of 160 petawatts (160 × 1015 W, or 1.6 × 1017 W), and a 3.5-year lifespan"
That's a lot of power from a tiny space.

"imagine if we could produce a microscopic black hole in a particle generator."
Ah yes imagine that.
Or if we could manufacture anti-matter (or other exotic matter) really cheap.
Or if we could construct a worm hole using neutronium.
Or if we could design an build a generation ship. Or a fleet.
Or if we could create cold fusion generators.
Or if those aliens that keep zipping around would actually drop off the design specs for those faster than light drives that they must be using. And those cloaking devices. Throw in anti-gravity while they are at it.
Or if fairies were real.

Merely for specificity due to my intimate knowledge of Space Aliens I submit those are not faster than light drives per se but bending spacetime drives.
