Paper Title: Flash and File System Co-Design to Increase System Lifetime

Paper Abstract: Flash lifetime is reduced by the write amplification factor (WAF) that results from extra write cycles generated during system operations. Filesystems add to the problem by generating a large number of writes when processing their own metadata. The additional WAF can have serious effects. A new metric (WAF-File) considers both flash and filesystem WAF. Designers can use it to co-design flash memory systems and filesystems to enhance overall lifetime.
