FIELD

The inventive concepts relate generally to storage devices, and more particularly to improved predicted failure of blocks in a Solid State Drive (SSD).

BACKGROUND

Solid State Drive (SSD) failures in the field may lead to a server shutdown and hence impair the performance and availability of the datacenter-scale applications. To prevent such unexpected failures, systems that employ SSDs usually use simple threshold-based models to avoid such failures by replacing the drives prior to their failure. Such protection mechanisms may either lead to high degrees of false alerts, or are not able to predict/avoid all the SSD failures. Further, in case of a physical error, the SSD is not able to recover from the error and hence avoid device failure.

A need remains to provide a fine-grained block failure prediction.
