Below is the improved smartctl output for my Samsung T5 500GB SSD connected
to the Rpi4 which seems to show that the drive temperature is around 40°C
and that the drive is healthy.
I get the same results with $ sudo smartctl -d scsi -a /dev/sda
Maybe one of these commands would produce an enhanced report with Transcend?

$ sudo smartctl -d sat -a /dev/sda
