We have Lenovo laptops at work with M.2’s that are OEM-branded Samsungs. One bricked itself in to read only mode after a few months. The other has been losing 1% health each week or so. I caught it losing 2% in just two days recently. These drives are older than the 990 model mentioned in the article but I have my suspicions anyway they’re dud drives. Nothing lost except time - they can be swapped under warranty. But…

Even Crucial are having tons of issues with current MX500 models.

I think SKHynix might be the last as they supply a lot of OEM over the years. But their consumer base is small so we don't have a huge sample size like Samsungs.

Apparently a few months ago it became known on the Chinese internet that the 980 Pro, 970 Evo Plus with new controller, and OEM versions are prone to getting unreadable sectors, where SMART 'Media and Data Integrity Errors' increases on every read attempt. https://www.reddit.com/r/buildapc/comments/x82mwe/samsung_ss... https://www.reddit.com/r/DataHoarder/comments/x8arle/psa_sam...

My anecdata: tl;dr: All 3 of my Samsung M.2 NVMe SSDs have failed in less than 3 years. 100% failure rate. My first SSD was a 1TB Samsung 970 EVO. It failed after 2 years and 8 months. It was replaced under warranty with a 1TB 970 EVO Plus. That replacement has now also failed after 1 year and 9 months. I bought a 2nd 1TB 970 EVO Plus in May 2019. It has now also failed (2 years and 7 months). Both are expected to be…

My anecdata, I've had 5 Samsung SSDs and they've all performed great.

I'd point the finger at your PSU or motherboard. That's way too many failures for it to be the SSDs.

Samsung couldn't stay in business if that was a normal failure rate.

Earlier quoted context omitted.

Worth checking if you have any thermal issues with it. Mine failed in a similar way due to presumably a rookie mistake of forgetting to remove the thermal pad tape on the mobo.

The controller is less thick than the NAND flash so don't make proper contact with the thermal pad. I just discovered mine is affected by this. After heeavy reading the controller is at 67C while the NAND is at 42C. https://www.youtube.com/watch?v=I8Z09nU554Q

Hmm, that still seems like it should be ok. Tjmax is usually over 100C (though for NANDs they recommend 70C I think)
