CVR do use SSD e.g. (
Aircraft Data Recorders | Rugged Solid State Drives | CWC-AE) selcted as it was one of the first results on Google.
However, beware when lookiing at the data you have for that SSD you use for logging. There is a difference between MTBF and drive endurance. SSD are only guarenteed to be written to a certian number of times. Enterprise grade drives are typically specified to endure 5 years of being written to a certain number of times per day. So you buy different endurance levels for different applications.
It is also not as simple as assuming because you can have 100k programme / erase cycles you can expect to write to the entire avaliable memory 100k times, short verison, you cannot write to individual memory cells, you have to write in blocks of cells, so even changing one wears many cells (
Write amplification) of course there are clever flash memory management algorithms in the SSD controller working to reduce these effects and extend life.
