Abstract
A pseudo Single Level Cell (pSLC)-scan-based storage device initialization system includes a chassis, a storage subsystem that is housed in the chassis, and a pSLC-scan-based storage device initialization subsystem that is housed in the chassis and coupled to the storage subsystem. The pSLC-scan-based storage device initialization subsystem reads respective subsets of pSLC data from the storage subsystem over a plurality of different read voltage thresholds, and identifies a first read voltage threshold that is included in the plurality of different read voltage thresholds and at which a respective first subset of the pSLC data read from the storage subsystem experienced errors within a predetermined error range. The pSLC-scan-based storage device initialization subsystem then uses the first read voltage threshold to estimate a powered-off data retention time for the storage subsystem, and performs post-data-retention initialization operations based on the powered-off data retention time for the storage subsystem.
