I am on the lookout for a good deal of NAS HDDs and found this one:

Not as good as the 14TB that is currently OOS, but still pretty good IMO.

Maybe something environmental in how you were running/storing them?
I've been running 6 of em for years (with robocopy scripts mirroring them in pairs) with no issues-- the pair of 8s I just replaced with a pair of 28s are about 6.5 years old and still working fine as I hand em down to a friend.... the last time I can recall any external spinning drive failing on me was a 4TB one maybe 10 years ago? (and its pair partner was fine, so no data loss-- in fact it's still working today elsewhere)
Or, forgetting personal anecdotes, Backblaze has failure rate data on tens of thousands of drives... out of over 10,000 8TB Barracudas, with an average age of over 8 years per drive, their failure rate is 1.52%
Failure rate on the 8TB EXOS enterprise drives BTW, over 15,000 of those, and only about 7.5 years average life, is actually slightly higher at 1.97%
The other user did say they have 2 of them for redundancy and they are right that the chances of them both failing at the same time is minimal. Only thing you have to keep in mind is that you will be using them in a way they aren't intended to be used. Besides that, if you can actually make it work, then more power to you
Our community has rated this post as helpful. If you agree, why not thank T.B.
FUN FACTS: 1) when BB massively bought and shucked externals (all brands, AFAIK) they found the non-enterprise HDDs from them fared AS WELL as the enterprise-grade HDDs they normally bought! This was 10 or 15 years or so ago, now. This should be encouraging news for Barracuda fans. Curiously, that still didn't stop BB from going back to buying Enterprise-grade when the HDD shortage ended (no sense in taking chances, I guess? Wicke_s stated some good points. The data was certainly clear). 2) Since its impossible to get long-term data on the current larger HDDs being manufactured at any given time, the best you can do is look at earlier smaller-capacity HDDs by Model and Manufacturer and guess/hope. 3) Historically HGST & then WD-UltraStars have consistently excelled over their competitors (SG, Toshiba, WD Reds and most other WDs) in reliability, but they don't come cheap. Although it may not be strictly adhered to, after the WD buy-out of HGST the UltraStar brand for retail is (or was) intended only for non-USA marketing, though you can buy them in the US. WD Gold is claimed to be almost the same as WD UltraStar and is retail marketed in the US (but I don't recall BB ever buying these). WD Reds (when introduced in the largest-size-of-4TB days and before the under-handed split into 3 different Red lines to confuse consumers) had a [well-hidden] Annualized failure rate of about 5% (horrible - BB smartly bought very few of these). But occasionally someone makes a REALLY bad model...and while thankfully rare it's always been a Seagate. 4) the well-known "bathtub curve" apparently doesn't apply to HGST and WD UltraStars, who actually seem to test every unit they ship - the high early-fail rate region doesn't seem to exist on these. SG, OTOH clearly doesn't test before shipping (admittedly anecdotal), so if you like to buy SG it is DOUBLY advisable that you unbox and test them immediately (don't shelve/stockpile untested NIB SGs). Of course that's good advice for any HDD anyway.
UNCORRECTABLE ERRORS: Toshiba only offers 1 in 10E14 models. Same for some WD Reds and other lesser WDs. And it can also vary by capacity within the same model! Beware of Red sometimes sneakily switching to "10 in 10E15" instead of "1 in 10E14". True fit-for-purpose enterprise-class HDDs should arguably at least be rated 1 in 10E15 (uncorrectable errors), given large multi-TB capacity HDDs these days.
But at the end of the day, these SG externals and Barracudas (and to a lesser extent WD externals) are SO INEXPENSIVE that they can be a compelling choice for many. The right choice depends on the buyer's risk aversion and willingness to spend more buying extra duplication-for-backups capacity (or a BB subscription) vs paying a higher cost PER TB at fewer total TBs (needs less Back-up capacity). If you can't afford or store extra HDDs, then the less robust HDDs are probably a "bad bet" for you unless you like to gamble with your data. If you can buy (or rent) extra capacity, you might want to buy the less robust HDDs, which sometimes approach half the cost. Comparing costs on an equal capacity basis makes little sense though: its "apples-to-oranges", because you probably should factor-in the cost of at least an extra HDD when buying cheap ones to really be comparing equally data-safe options. The SG IronWolf Pro rated claims put it near Exos and Ultrastar (IWP may be a bit quieter[? - dunno] than Exos) in specs, but if the price is equal I'd take the UltraStar any day over these SGs.
And to anyone out there who's tempted: please spare us the ever-returning "but BB isn't using HDDs like a home user" argument garbage. While POSSIBLY pertinent (to some in-determinant unproven extent), that BB data is the only reliable data we consumers have to go on. We'll take it, with Thanks. :-)
Right-- but that was actually BETTER than the Enterprise drives over a similar period. Which I definitely did mention and was the entire reason for referencing that data to someone who was saying Enterprise drives are better for storage longevity.
When doing 10,000 drives even a single-digit-percent failure rate gets you enough failed drives that a 5 year warranty would be a cost saver if the upcharge isn't massive.
None of that would really apply to a home user--- especially one with the option to use a good credit card that adds 1-2 years on that 1 year warranty.... Paying 2x the price for a 5 year warranty vs 1x for effectively 3 years doesn't make economic sense for a home user.
And cheap externals provide that a lot more easily than expensive enterprise drives for home users who aren't hammering drives 24/7 in data centers and losing $ every second of downtime.
So one place people get tripped up, and I alluded to it above, is redundancy vs "backup"
RAID is redundancy. 1 (or more, at some levels of RAID) drive can fail and you don't lose any data from that failure. The simplest here is RAID1, where you have a pair of drives and data is mirrored between them.
If one drive dies other still has all your data, and you can just replace the bad drive, rebuild the mirror, and you're fine.
This is NOT BACKUP.
Because if say a virus wipes (or encrypts or whatever) all your online drives, your data is gone (or held ransom).
Backup is that data stored elsewhere that some catastrophe on the local machine can't kill it. This can be some cloud backup (which costs $, potentially a lot if you have a LOT of data- and is dependent on the speed of your internet connection of course) or other physical storage you own (which costs a lot more upfront but isn't an ongoing cost). Cloud has advantages in that you can automate updating the backed up data, and being physically off-site if your house burns down or something- but you're also trusting a third party to keep and protect (and if needed restore) your data.
The gold standard here is the 3-2-1 rule... You have 3 copies of your data (the actual production one, and two different backups- say one physical and one cloud). You store on at least 2 media types (physical disk and cloud or tape), and at least 1 copy is stored offsite from the production data (cloud, or storing physical media at a bank or a friends house or whatever).
Personally the bulk of my data in terms of space taken up is media... I COULD replace it if I had to, though it'd be a PITA. For me, RAID1 and a single backup to another system is plenty for that... YMMV. For actual critical stuff I can't replace (personal photos, audio, tax records, etc) I do hew nearer the 3-2-1 rule, but it's a ton less data, small enough it easily fits on removable storage I can store elsewhere. Again YMMV
