I have only ever had 1 failure, a WD 4TB drive about 8 years ago (only used for backups, so not really used!), got it replaced under warranty.
I'm surprised they replaced it. Did the guy on the phone say, "okay, but just this once" ? That's what they told me after the drive failed on less than one month of use. That was nearly ten years ago, but that man did not know how right he was as I have never purchased a Western Digital hard drive since. I've had WD Blues fail on me numerous times, WD Greens, and the first and the last WD spinner I returned was a WD Black. Perhaps they upped the quality since but I'm not taking any chances.
I live in the north, in Canada. Perhaps the reason for the failures is due to all the bouncing around the packages suffer in shipping. This would not explain why any Seagates I own have significantly out lasted nearly all the WD spinners I've ever owned. This is not to say Seagate never made crappy hard drives. The old style "slim" 500GB 3.5" spinners also tended to crater on me easily, but anything 1TB or higher seems safe with Seagate.
Now to be fair, I have an array of WD
Velociraptor drives that must be around 16 years old still spinning happily in my X99 build. They have never given me any trouble. So I am guessing the very old WD spinners (Enterprise class) were well built. The old
Caviar Blacks used to be pretty good too, but the only way you'll get these now is if you buy used. This led to some research on my part at one point. Based on my findings this is my advice:
1) Ignore the shills. The best hard drives (mechanical) are CMR. Avoid purchasing SMR drives. Make sure of this before you buy.
2) Enterprise class drives tend to last longer. They cost more but they'll save you money in the long run.
3) If money isn't a concern but durability is go with Helium filled drives such as EXOS or the old HGST HUH drives.
Shingled magnetic recording (SMR) is notorious for short life spans. Conventional magnetic recording (CMR) will cost a bit more but is much more durable. Helium filled drives last long because there is no oxygen inside them to corrode the parts when the drives get hot. Unfortunately, Western Digital has bought out HGST so the only way you'll be getting the older style HGST drives is if you buy used. I'm currently experimenting with Iron Wolf drives and so far these are proving to be reliable hard drives. The Toshiba NAS drives I'm using are also proving to be a wise choice. What they have in common is CMR. My advice is that if you simply must buy a Western Digital spinner make sure that it is a CMR drive first.
Here is an example of some of the drives I'm currently using in my main. Other drives (external) have been switched off. I own about a dozen devices using various multiple drives and most of them multi-boot. I think I know to some degree from whence I accumulate my knowledge but experience is subjective. Factors like geographical location, climate, quality control, and bureaucracy should also be taken into account.
