Thanks for the images and the report, yes, now I see!
Sorry, to be honest, I was confused: I thought you have a hybrid drive (which is a hard disk and SSD in the same housing).
Many manufacturers use that solution: where the SSD is used for cache - but from the viewpoint of the operating system (and the software) these two devices appear as a single drive which can store data.
But now I see that this situation is different: there is a "normal" 500 GB hard disk plus this SSD. These are separate devices, these can be diagnosed, tested (and hopefully repaired) independently.
The random positioned read errors suggest that the SSD is not able to properly operate: sometimes the data can be read - but sometimes it is not.
The best would be to force the SSD to refresh the complete contents - or even perform a complete rewrite of data.
Personally I'd try to use Disk menu -> Surface test -> Read+Write+Read test. This should read, refresh and then write back data plus read again to verify if it's readable and same as with the old, previously stored information.
This test exactly created to attempt repair of flash drives when the stored information is not (or not always) readable or may be corrupted.
If the above test does not help (there may be still problems after it), then you may try Disk menu -> Surface test -> Reinitialise disk surface on the SSD.
This forces the drive to repair the sectors and then it may be better to use, so a repeated read test may show no problems at all.
But please note that this will delete the contents of the SSD completely.
If I'm correct (according the report) the SSD contains no user partitions/data, but anyway, be careful.
If you can send new developer report(s) after the tests, it is possible to check possible changes in reported values, verify how the status and the internal error/status counters change. This may help to even more detect and report problems with such particular SSD model.
And if these still do not help, I'd ask for a replacement of the SSD, because it may not able to hold data properly (even if it's health seems fine).
