READS AND WRITES BETWEEN CONTIGUOUS DATA BLOCK AND NONCONTIGUOUS SETS OF LOGICAL ADDRESS BLOCKS IN A PERSISTENT STORAGE DEVICE

摘要

In this disclosure, persistent storage includes both persistent storage, which includes a set of persistent storage blocks, and storage controllers. The persistent storage device stores and fetches data in response to a command received from the external host device. Persistent storage stores data from adjacent data blocks in two or more sets of logical address blocks in persistent storage. The persistent storage also fetches data corresponding to adjacent data blocks from two or more sets of logical address blocks in the persistent memory. In both cases, two or more sets of logical address blocks in the persistent store are not entirely contiguous.
