Inside the SSD controller brain the compressibility of data is one of the tools which can go into the mix of optimizing performance, endurance and competitive cost.

A paper - A Survey Of Architectural Approaches for Data Compression in Cache and Main Memory Systems by Sparsh Mittal and Jeffrey S. Vetter in IEEE Transactions on Parallel and Distributed Systems - reviews the published techniques available and places their relevance in the context of real and future memory types and applications.

The survey covers applications from embedded systems upto supercomputers.

In addition to being useful resource directory of related papers the article gives you a brief description of many compression techniques, where you might use them and what benefits you might expect.

See also:- list of articles and books by Sparsh Mittal which among other things covers caching techniques, reliability impacts and energy saving possibilities in a wide range of server architectures.
