My understanding is that the SSD's ability to retain data decreases
with the number of writes, and that number gets smaller as the memory
cell geometry gets smaller:

I have a couple of SSDs in my main DAW as they are fast and silent, but
I'm very careful to back up to conventional HDDs as soon as possible.
I'm willing to be convinced that this is over-cautious if anyone has
some hard numbers on this.
