So apparently inventing your own SSD caching system is all the rage? We already had flashcache from Facebook : https://github.com/facebook/flashcache/ And bcache : http://bcache.evilpiepirate.org/

However this one isn't kernel-based, so it won't help your NFS server or your postgresql engine. On the other hand it's much easier to build.

Block devices and memcached are totally different; of course you're going to need different implementations for different APIs.

However a block layer cache can enhance any kind of IO.

All these level caching systems work mostly on different layers, bcache deals with the block layer, flashcache deals with device mapper et al and so does enhanceio.
