Abstract
A data storage device includes a first data storage medium having a first capacity and a first speed, a second data storage medium having a second capacity and a second speed, and a device controller for interfacing between the data storage device and a host system. The second capacity is greater than the first capacity and the second speed is slower than the first speed. The device controller presents the data storage device to the host system as having a device capacity at least equal to the second capacity and a device speed at least equal to the first speed. The first data storage medium may be a solid-state drive while the second data storage medium is a hard disk drive. The device controller may be a solid-state drive controller, or a hard disk drive controller that may accept at least one solid-state drive command, such as a TRIM command.
