Sorry that I don't know much about SSDs but what do you mean by "their drive will go readonly"? Can you elaborate? Thanks.

SSDs have a limited number of total write cycles they can undergo before they wear out. See e.g.:

In addition to what's been said, Flash cells lose data over time and need to be rewritten.

The controllers take care of this. But an SSD that has gone read-only, assuming it can in fact go read-only, is an SSD that will quickly lose all its data.
