Abstract
Method and apparatus for enhancing power cycle performance of a storage device, such as a solid-state drive (SSD). In some embodiments, map data that describe the contents of a non-volatile memory (NVM) are arranged as snapshots and intervening journal updates. During a scram interval in which the storage device transitions to a powered down condition, the snapshots and journal updates for primary segments with high client interest are updated prior to storage to the NVM. During a reinitialization interval in which the storage device transitions to a powered up condition, the updated primary segments are loaded, after which the storage device provides the client device with an operationally ready notification. Remaining secondary segments are updated and loaded after the notification. The primary segments are identified based on a detected workload from the client device. Configuration changes can further be made based on the detected workload.
