I wanted to bring back an old question, but with a twist. It has been answered, how an SSD could be used as a caching drive for a larger, mechanical drive. What I am looking for is to have the same, but for a drive which is encrypted with TrueCrypt or BitLocker
This question is about windows. I am aware of linux solutions, such as flashcacne and bcache. They all work on a block level, therefore could be used on top of encrypted volume, transparently. When SSD dies, the underlying file system on block device is intact, could be mounted by itself. Very elegant solution, and works very well, but the question is about Windows.
I am not certain about how Windows caching solutions (ExpressCache, DataPlex, etc) work. If SSD is used caching on top of already mounted drive, then encryption is as good as non-existent, because all the files you work with are cached unencrypted on SSD. Has there been any research on possible solutions, where it is verified, that Windows is not writing any plaintext data to SSD?
Maybe, a hardware solution?..
