You can see SMART test results with "--log=selftest" parameter.
     # smartctl --log=selftest /dev/sdZ

Can you post back the output from "smartctl" with "--all" parameter for 
this device?
Usually cheap and\or old SSDs have a limited SMART information, but it 
still worth to look.
For reference, here is the output for one of my consumer grade SSDs 
(2-bit 2D MLC NAND), used as system disk for two OSs:
https://paste.debian.net/1190136

It was used daily for 23932 hours (attribute #9) and still reports 99% 
health left (attribute #231).
