Improving SSD lifetime with byte-addressable metadata
Yanqin Jin, Hung‐Wei Tseng, Yannis Papakonstantinou, Steven Swanson · Proceedings of the International Symposium on Memory Systems · 2017
Existing solid state drives (SSDs) provide flash-based out-of-band (OOB) data that can only be updated on a page write. Consequently, the metadata stored in their OOB region lack flexibility due to the idiosyncrasies of flash memory, incurring unnecessary flash write operations detrimental to device lifetime.
