A data storage device is configured to boost either capacity or performance using a set of reserve memory blocks. The data storage device includes a storage media and control circuitry. The storage media includes first set of memory blocks at a first capacity level and a first performance level and a reserve set of memory blocks. The control circuitry is configured to, in response to receiving a selection of a first storage mode from a user, allocate the reserve set of memory blocks to provide a second performance level greater than the first performance level. The control circuitry is further configured to, in response to receiving a selection of a second storage mode from the user, allocate the reserve set of memory blocks to provide a second capacity level greater than the first capacity level.

Selectable performance boost for storage devices

A data storage device includes storage media and control circuitry and is configured to enable the creation of partitions with different performance levels. The storage media includes a first set and a second set of memory blocks having different performance levels. The control circuitry is configured to: in response to a request from a host system, provide performance data from the first set of memory blocks and the second set of memory blocks to the host system. The control circuitry is further configured to: receive partition settings from the host system, the partition settings creating a first partition including at least part of the first set of memory blocks and a second partition including at least part of the second set of memory blocks, wherein the first partition has a better performance level than the second partition; and save the partition settings to the storage media.
