In case it helps anyone - I bought 3 of these last month from Best Buy and put them in a TrueNAS Scale server I have after error checking them. Transferred 18 terabytes onto a RAID-Z1 array and no issues reading and writing at normal speeds.
No clue if the drives are CMR, SMR or whatever. They work for me. I keep redundant backups. I wouldn't trust these or any drives without at least one other backup of the data somewhere. All drives fail sooner or later.
Things that piss me off:
This comes brand spanking new with 1yr warranty.
You buy a beat up 5 yr old drive from one of the refurbishers and comes with 3-5 yrs.
Just lets me wonder how much faith have we lost in the retail type of drives...
It's more consumers don't look at warranties. A split between cost driven consumers waiving then for the lowest price, and some either accepting they'll never claim them and/or that it's too complicated to do.
For the savvy there's also whole home tech warranties, and for many of us with a Best Buy worth of tech at home, that can pencil out.

Some people were saying that these are Seagate Barracuda ST20000DM001 can you confirm? I had those in my NAS and they died after a little over 2 years , there is no warranty if you shuck them. You only get around 150 MB/s .
Seems like these drives are a crapshoot based on the hundreds of comments between here and reddit. I rolled the dice and picked one up yesterday.
FWIW the copy I have is quiet and averaged 158MB/s transferring 9TBs of data over USB from another USB external. Seems comparable to other Seagate and WD external drives I've picked up over the years. Its still in its enclosure for now, if I don't see any issues with it within the return window I'll be shucking it and throwing it in a DAS used for a media server.

This exact drive, which just showed up anywhere in 11/2024.
I have a pair of these in a mirror configuration using Windows Storage Spaces. Backed up over 15TB in one go and it was able to maintain about 250MB/sec the entire time. Of course, I do have an external fan blowing on them, as these heat up like nobody's business.

Bought two last year, good deals but they are noisy/vibration and never had a noise problem like that with WD. And today this happened, which is scary.
... because they have a QUALITY CONTROL monopoly... seagate drives are mostly garbage... thats why you see a "sale" on them literally every week. Effing sad state of the hdd market... wish there was a viable competitor that is NOT seagate... what else exists is NOT COMPETITIVE

There's always Toshiba.

Sucks that these drives appear to be a major risk to purchase. HDDs are way too expensive now. Last 18TB exo I bought from goharddrive was $180 in 09/24. Usually prices go down...Hopefully there will be some better deals this President's weekend
The price of recertified drives has skyrocketed. In the last few months, they've risen somewhere in the ballpark of 50%.

BestBuy reviews have a picture. The drive inside the casing is a HAMR (heat-assisted magnetic recording ) hard drive using Shingled technology (SMR).
The tell-tale is the laser certification label.
This video talks about HAMR (and other tech news.), starting at 20-second mark.
I'd like to know what source that AI is using to determine the drives are SMR. I still haven't seen any evidence that is true.
I used Google search. I had searched the BarraCuda HAMR hard drive about a month ago. I got a totally different answer. The search told me Seagate only used CMR in concert with HAMR. I saw the same redacted picture.
i recommend waiting for the 22TB or 24TB and spend the extra few bucks, better data center drive, EXO or a WD and stay far away from these 20TB drives. Unless of course you just need a basic single drive in your desktop.
no way i will ever use these in true nas . Maybe unraid if i can determine if they are CMR
no specs listed and software really doesnt tell us. Also WD has used SMR drives before without telling customers the real specs.
AI Overview
unaware of the SMR implementation.
Key points about this issue:
Hidden SMR:
Some WD drives, particularly lower capacity WD Red NAS drives, were found to utilize SMR technology without clear disclosure in product descriptions or specifications, leading to customer complaints about unexpected performance issues.
Impact of SMR:
SMR drives can have significantly slower write speeds compared to CMR drives, especially when writing large amounts of data consecutively, making them less suitable for applications like NAS (Network Attached Storage) where frequent writes are common.
Customer backlash:
This practice drew criticism from users and tech communities who felt misled by WD's lack of transparency regarding SMR usage in certain drives.
