I've only really experienced drive locking and freezing which resolves on a reboot, this is concerning enough. I haven't experienced any endurance issues.

I always suspected that it may be ability for laptop hardware to handle the second drive as performance was not as quite as performant as primary slot. Both slots are rated for PCIE 4 though.
It is strange though that after the firmware update there have been zero freezes.
The new firmware is version 5B2QGXA7, updated via magician on Windows. I didn't make a note of earlier firmware versions. It's still too soon to know if the ssd freeze will reoccur.
I installed 2 x 980 Pro 2Tb in a laptop in Nov 2022. Running a daily Robocopy bat script to backup a folder in C: to D: would freeze a couple of times a week and lock the D: drive. After reboot, a drive check would find no errors and everything would work as normal. I've used the same script for years with no issues.
Since the firmware update last week Robocopy has not frozen the drive at all this week.
