I don't recall if you mentioned the model of SSD you have. I wonder if it has SMART
What is the output of
sudo smartctl --all /dev/sdX
where X is the device identifier
I put the disk in a USB3.1 box. It says:
smartctl 7.0 2019-03-31 r4903 [x86_64-linux-5.2.13-200.fc30.x86_64]

/dev/sda: USB to NVMe bridge [please try '-d sntjmicron' and report
result to: smartmontools-support(a)listi.jpberlin.de]
Please specify device type with the -d option.
Use smartctl -h to get a usage summary
The other new one gives much more information. I should probably try
when plugged directly to the mother card.
