Well, I guess it is still the best, or one of the best performance-wise? And I did read they put out a fix for this issue:
https://www.tomshardware.com/news/samsung-990-pro-firmware-update-released-ssd-health .
However, that fix apparently stops the degradation but doesn't reset the SMART values of the current degradation. That leaves it a little unclear to me if the degradation is real, or just numbers? One idea in that article says it could be real if they couldn't fix it with the firmware update and just reset the values.
Maybe we said this all already... I'm having forum deja-vu
