What are the signs of an SSD that's about to die?

anecdotally i'd see filesystem errors and write speed dropping, sometimes writes practically hanging, especially if the drive is close to 90% capacity.

SMART monitoring.

In my experience the SMART data on SSDs is pretty good at pointing to failures.

Either that or the SSD simply disappears from the system. But that happens to HDDs also.
