摘要： A solid-state drive, a solid-state drive access unit allocation/data storage approach, and a solid-state drive access unit access/data retrieval approach are described that improve the efficiency with which data, that has been stored to the solid-state drive in association with a series of logical block addresses, can be retrieved from the solid-state drive. The described access unit allocation approach assures that data stored in the solid-state drive in association with a sequential series of logical block addresses is stored and maintained in solid-state drive access units, i.e., addressable units of solid-state drive memory, that allow parallel read access to the data via parallel memory access I/O channels internal to the solid-state drive. In this manner, the time required to retrieve data associated with a sequential series of logical block addresses from corresponding access units within the solid-state drive is reduced.

摘要： A system includes first memory configured to store first metadata to associate logical addresses with physical addresses. Second memory is configured to include the physical addresses, to store first data based on the physical addresses, and to store portions of the first metadata when a status of a predetermined group of the physical addresses is changed. A recovery module is configured to update the first metadata based on the portions of the first metadata stored in the second memory.

摘要： A method and other embodiments associated with solid-state drive command grouping are described. In one embodiment, a first command and a second command are grouped into a command pack, where the first command and the second command do not share a common channel for execution. A solid-state drive is controlled to execute the command pack on the solid-state drive, where executing the command pack causes the first command and the second command to execute concurrently on separate channels.
