It's crazy to me, the lack of transparency about TLC and QLC NAND types from SSD manufacturers given what a difference it can make (depending on use case), especially when your drive is almost full. I had no idea about it until recently, and nowhere on the spec sheet on MSI's website does it mention it's QLC.
I have an MSI Spatium 371 NVMe drive, and it also is QLC, which I didn't know about until well after I bought it. Its performance has been fine for me, since I'm not doing a lot of heavy writing to it and thus not prone to filling up its SLC cache. But it would have been nice to have been informed about such things beforehand.
Wait until the dread day when PLC is a thing and QLC is the new high-end NAND type...
