Regular file system crashing (after reinstall macOS lives shortly - days with OS X file system, hours with APFS).

Sounds like the SSD is at end of life :-(

Disk Utility can't finish disk checking on I/O error in one of file system components and leaves me one option: erase disk and reinstall OS. Endless circle.

Definitely like the SSD is at end of life :-(

I/O errors are report that a drive is failing as data can't get In or Out; not that there's some software issue.

In all cases SDD status showen as S.M.A.R.T. but I start to think about SDD incorrect working as the most probable source of my problem.

I've only ever seen SMART errors being reported on a faulty drive once. In most cases, the drive fails before SMART reports a problem.

Is it time to change my SDD?

I suspect, yes!

Sorry but this really looks as though it's time to replace the SSD. :-(
