Abstract
A storage device minimizes updates to compressed msets based on a priority criterion. The storage device includes a memory including a logical-to-physical (L2P) table divided into msets that include a range of entries in the L2P table. The storage device also includes memory to cache a first set of msets. A controller on the storage device accesses the first set of msets to quickly read data from and write data to the memory device. The controller determines a uLayer state for a first mset in the first set of msets, a read ratio for the first mset, a prediction for the first mset, and/or a queue depth for the first mset in determining whether the first mset meets the priority criterion and is ready for compression. The controller assigns a high priority to the first mset if the first mset meets the priority criterion and compresses the first mset.
