I used to work in their SSD vertical on the software side. For what it's worth, SSD/memory business unit is their pride. They never used to cut corners and do rigorous testing to ensure their customers aren't screwed over. Even when a bad batch of SSDs were shipped by mistake, they would recall/refund all of them proactively. When ever a new model is released, they would first ship limited units to a set of SSD enthusiasts including gamers in Korea. One such time, there was a BSOD reported by a single tester in some edge case - > they sent a lot of team members in person to chase and fix that issue.

So I really doubt they would do anything stupid to get some quick bucks at the cost of reputation.

On the other hand, their smart tv division is absolute garbage and employees themselves wouldn't buy Samsung TVs.

With the introduction of QLC consumer SSDs, with worse write endurance and life time but the same price as TLC, I took a look at used enterprise SSDs and never looked back. The only issues is the connectors. You need 8x PCI-E lanes (4x might work) or a SAS connector that nearly no consumer board has.

U.2 to PCIe mounter or U.2 to M.2 cable is fine.

As a legal layman, is this possible class action territory?

IANAL, but I believe that as long as they reach their advertised speeds, they’re fine. Alternatively, you would need to prove malicious intent to deceive the benchmarks; but I can see Samsung make the argument for “we had to change to different $supplier because of chip shortage, and we incremented the revision number accordingly, and still reach advertised speeds”.

Something doesn't line up here. The "old" model number in the ars piece is given as MZVLB1T0HBLR, which corresponds to a PM981a according to Samsung's website. Was that ever sold as a 970 Evo Plus? https://www.samsung.com/semiconductor/ssd/client-ssd/MZVLB1T...

It would seem to be the case. lshw reports the controller on my 970 Evo Plus as "NVMe SSD Controller SM981/PM981/PM983"

The downgrades seem to be prevalent across the Evo (Plus) range, for a while now. I got burnt twice, on two different microSD cards -- one was for a Raspberry Pi (64GB) in Jan 2020, and another quite recently for my S20 (128GB). The 256GB version was not affected by the downgrade to a lower write speed.

Initially, the changes in lower write speeds from 90MB/s to 60MB/s were not communicated, either through a press release, or via the specs on the Samsung site. However, it was eventually updated, i.e. the change of letters indicating different model numbers: MB-MCxxxGA vs MB-MCxxxHA, the latter suggesting a new '2020 model' with inferior write speeds.

Samsung’s pride and butter is their SSD group? I find that hard to believe… they provide a range of products, including cars (they dominate the SKorean auto market), as well as financial services (in S Korea).

In America, they have TVs, and cell phones. I find it very hard to believe SSDs are their pride and butter

How are Samsung Smart TV’s garbage? I mean, they have ads and crap in some markets but so do all their competitors.

I have a Samsung TV which has great picture quality, decent design and plenty of useful options for a very reasonable price.

America doesn’t represent world. In asian countries, Samsung and WD controls almost entire SSD market
