Abstract
A data storage device can use a jump range to identify whether a new write command received from a host is part of a sequential stream of write commands even though the logical block address of the new write command is not sequential to the logical block addresses of those other commands. However, using a fixed jump range can result in a new random write command being misclassified as a sequential write command, or vice versa. To address this problem, the embodiments presented herein describe a data storage device that uses a dynamic jump range based on a pattern of write commands previously received from the host. Other embodiments are provided.
