Does that mean I get another 2 dollars for that class action if I buy it and become outraged?

Right, I had to google myself, because I can never remember. So, the conventional wisdom is CMR better than SMR.

These are "WD Red" and are SMR.
The "WD Red Plus" are the better and CMR.

WD has really muddied the waters, s it's no longer so straightforward. There are older WD Red (the newer are now named 'Plus') that are CMR, like the EFRX series. There are also WD Blue (my gotos for ZFS NAS) that are CMR, like the EZRZ and EZAZ series.

Consumer grade mechanical hard drives by Seagate and Western Digital should be avoided if you care about your data. Get an enterprise hard drive filled with helium, it will last you a very long time.

That's one way to go if you like to take chances on "renewed" HDs, and you don't care about noise. I've been there already. I got four, and each of them had 5 years on them, and all four failed within a month. BTW, all from the same source as you linked to (but through Newegg), and the guy refunded the money, no questions asked. At least that, but I'm not going to do that again.

ZFS file system, ECC system memory, light use, ~4.5 years and still going strong. I have yet to have one fail on me, though I always keep a spare and replace when I'm starting to get errors. I've been doing it for years (decades really). Just got two more 4TB EZAX @ $75 ea.

C stands for "Conventional"
S stands for "Shingled"
MR means "Magnetic Recording"

In most (arguably all) applications, CMR is best.
Shingled (SMR) has the data overlapping, like a shingle. While this doesn't really affect reading the data, writing new data means all of the overlapping data has to be moved out of the way first. and all of the overlapping data on top of that has to be moved as well... and so on...

It's fine for archival purposes, write once and store as a backup, etc... but for everyday use, SMR is terrible. In a NAS it's even worse, particularly one that uses ZFS. It can make a RAID array that would usually take 12 hours or so to rebuild with a CMR drive take several weeks on an SMR drive. That is what made these drives so maddening. SMR is the worst performing drive you could put in a modern NAS, yet that's what WD labelled them for without telling anyone they did it.

Thank you for the explanation. Never knew that's how it worked or that they did it without telling anyone.

If I am putting some photos on a backup that I will probably not touch again for awhile, this will probably be fine, correct? Otherwise get the "plus".

Personally, I just stay away from SMR altogether. I tend to swap my drives around and repurpose them though.

As far as I know, there's no benefit to the end user to use SMR, it only benefits the manufacturer because they can squeeze about 30% more data on to each platter.

I would use those reconditioned 4TB Ultrastars that someone linked in this thread long before buying SMR drives. That's just a personal preference I suppose, but HGST makes insanely reliable drives, especially their enterprise line. Sucks that WD bought them.

Off Topic Nostalgia Time:
It's funny that back in the day, Hitachi bought IBM's Hard Drive division, but didn't change the model names at all. Anyone who knew anything about computers knew that IBM's consumer drives "DeskStar" had been referred to as "DeathStar" for several years at that point due to their horrible reliability. I learned in the mid 2000's that Hitachi "DeskStars" were some of the most reliable drives you could get, yet they could often be found cheap because people still had that model name association.

After the flood in Thailand that ground WD to a crawl and caused the market to get desperate, everyone else soon learned Hitachi drives were awesome too. and the "Deathstar" moniker was all but forgotten.

I've had hit-or-miss luck with second-hand drives, but I always run a full battery of tests using Seatools before putting data on any newly purchased HDD I get. The faulty drives have always shown themselves during the long generic test or sooner, and I'll send the drive back as "DOA".

That goes for new drives as well, and I've found my share of soon-to-be-failing drives by just letting those long tests run. Send back as DOA within the 30-day return period, never have to deal with the manufacturers or lose any data.

I had one take a shit on me after 4 years. I was running it in RAID 1 though because it was sentimental.

So you are complaining after 4-years, your internal hard drive quit on you. Most of the crap sold to consumers doesn't even last that long.

Your hard-and-fast rule (more like a blanket conviction with a dose of fear mongering) is not incorrect per se, and yet manages to be wrong for a whole gamut of use cases.

In a home environment HDs are most of the time just spinning idle. In such case, consumer-type HDs, like the WD Blue line, are parfectly fine (as the SMART data I posted shows).

On the other hand, if you are in a commercial environment where HDs are pushed to their mechanical/thermal/electrical limits most of the time, then you may(*) need, and can justify their price, drives capable of delivering 100s of TBs over their lifetime, like the mentioned HGST made ones.

To each his/her own and according to their needs (ha!), so oftentimes the "crap" drives, as you call them, are the most suitable solution.

(*) Spend some time looking through Backblaze reliability reporting.
