Any medium can fail with no warning. Good backups have always been the
go-to recourse for these occurrences.

Yep. Like I described earlier in the thread.

Most SSD controllers will move data in the background so that wear
leveling really is leveled across the entire array of flash cells.

I suggest looking at EnhanceIO. It works a lot like Intel's SRT, using
the SSD as a cache for slower block devices. You'll get the flash read
performance benefits without the worries about flash wear. Sure, the
cache drive will fail but that failure won't damage your data.
