US Patent 9977623 Detection of a sequential command stream

A data storage device includes a non-volatile memory and a controller coupled to the non-volatile memory. The controller is configured to receive a first command from an access device, the first command associated with a first logical block address (LBA). The controller is also configured to, after receiving the first command, receive a second command and a third command from the access device. The second command is associated with a second LBA that precedes the first LBA, the third command is associated with a third LBA that succeeds the first LBA. The controller is further configured to determine that the first command, the second command, and the third command correspond to a sequential command stream.
