I’ve thought WD was sleezy ever since they secretly switched from CMR drives to SMR drives, including in their NAS products (for which SMR drives are particularly unsuitable). So this doesn’t surprise me at all.
People need to stop buying WD drives and buy Seagate instead. They had their own SMR scandal, but at least they never put them in their NAS drives.
Ehhhh, you aren’t far off. Star Trek jargon was literally made up by the actors and writers, at least according to some of the original cast, with them mimicking the technical jargon that their friends in technical careers, especially electrical engineers, were using at the time.
I am tech savvy and I’ve never heard of SMR or CMR. After reading up on it, I don’t think it really matters. SMR is newer technology, and is maybe more reliable in the short term, but the drives fail faster because of the extra wear and tear, and the drives are slower than CMR.

Edit: I missed that SMR is supposed to be worse, despite being newer. So I guess WD is putting slower and sooner failing drives out to save a buck.
I used to buy Seagate, but they broke twice or thrice as fast as WD. But that was 8-10 years ago. Are they better now?
Yeah, my experience with Seagate has sucked.
A few years back i got a failed drive replaced under warranty… died like 6 months shy of its 3 year warranty date. They said they’d replace it and sent me a refurbished drive. It died shortly after it was plugged in, before I’d even started copying files to it. I could literally hear something rolling around in the drive. They replaced it again and the new drive failed similarly… plugged in for a while and then windows started reporting it was not accessible. 3rd drive worked, and still works, but I sure as shit don’t trust it and haven’t bought Seagate since.
Each manufacturer has their bad batches tbh. I’ve got 12 WD 3TB’s that have been running without a single failure for years, but of the six 4TB WD’s that I bought later five have died already. I’ve been replacing those with 8TB ironwolfs, which have so far been behaving well.
The only time I’ve had drives from either company fail was when I knocked my drive cage off the desk while it was running; they’ve all been very reliable otherwise. Seagate drives are usually less expensive, though.
In active service I currently have 5 WD CMR drives, 1 WD SMR drive, 5 Seagate CMR drives, and 2 Seagate SMR drives. I also have 1 WD drive in storage. All WD drives are “Red” (the CMR ones now being called “Red Plus”), the CMR Seagate drives are “IronWolf”, and the SMR Seagate drives are “Barracuda”. My oldest WD drive is from 2018 and my oldest Seagate drive is from 2020.
Seagate drives should never be used outside of a RAID because the failure rate is so high.
WD is absolutely abusing their power as the only reliable spinning HDD company left, but I have no choice but to continue to buy their increasing overpriced drives because there is no alternative.
From what I understand, SMR is fine for NAS as long as you aren’t doing a lot of reads. Like hosting a multimedia server that pulls videos and stuff from the NAS. I recently stood up a TrueNAS server a few months ago with SMR WD disks and it works fine for my use case. It’s RAIDed and backed up to cloud storage. I’m now looking into standing up a media server, but I won’t use that NAS storage for that.
The real downside to SMR drives is “random” writes; adjacent tracks need to be re-written, and then their adjacent tracks, and that keeps going until the tracks adjacent to a write happen to be empty. It doesn’t matter much for long sequential writes (because adjacent tracks will be overwritten anyway). I think the re-writing process also hurts read performance for the host, but reads alone don’t cause rewriting.
If you need to reshape/resilver your array (grow, shrink, or change geometry), it’ll probably take weeks or months with an SMR drive compared to days for a CMR drive.
I got burned by WD’s secret SMR drives in my home NAS and they sucked! They were marketed as NAS drives, but the performance was abominable, the failed sector count grew steadily from day 1 and it felt like they failed 1 early. Once the whole sordid fiasco came to light I switched to Seagate CMR drives and everything has been mostly OK since then.
