Abstract
A data storage device has a cache and a non-volatile memory. Instead of flushing the entire cache to the non-volatile memory in response to a command from a host, the data storage device flushes only the cached data that is associated with an identifier provided by the host. This allows the cached data associated with the identifier to be flushed more quickly. The data storage device can also prioritize queued commands that are associated with the identifier.
