Abstract

See full text

Various embodiments for predicting hardware lifespan by a processor device are provided. For a solid state drive (SSD) device configured with data deduplication mechanisms, trend information is obtained by comparing a write tracking table to a de-duplicated cell tracking table to determine how many new cells were allocated on the SSD device over a particular time period. The trend information is applied to at least one drive constant data to predict the useful remaining lifespan of the SSD drive device.
