SMART isn’t much use, anyway. I test my storage devices for actual I/O
errors.
By the time any type of storage device is reporting errors during actual use, it's already in a really bad way, and should have been replaced.
Both spinning discs and flash media are over provisioned with a number of spare sectors/blocks which they will silently map in, either over sectors which have started giving read errors, or any flash blocks which have reached their write limits and could be unreliable.
The SMART information on the drive will tell you when this happens, long before the OS finds the disc has started to be come corrupted. Use this as the first warning to replace the disc before data loss or complete failure.

Exactly.

Raw error read read is there, also something you wouldn't find outside SMART - reallocated sector count plus erase fail and wear levelling counts
