Actually, we already added several enhacements for optimization of SSD drives in the PGP Desktop 10.1.2 code. Some is to help with the wear-level issue as well as doing read ahead caching. Also taking advantage of new chipset features like the AES-NI instruction set for one.
Before the release, we had about a 60% performance degredation on SSD drives and it was putting more wear and tear on the disks. Furthermore, we just recently fixed an issue with apple's driver in 64-bit kernel mode when encrypting on certain Mac SSD drives. I know that they will be doing more code changes in the new release, 10.2, which is due out sometime August-September 2011 timeframe.
But I'm not sure what additional features we are adding for SSD there yet.
