Abstract:
A Data Storage Device (DSD) includes at least one disk for storing data in a plurality of storage areas including at least a first area type for using a first data access methodology and a second area type for using a second data access methodology. It is determined whether to perform a command in a storage area of the first or second area type. If the command is to be performed in the first area type, the command is prioritized over at least one other command for the second area type. In another aspect, a value is determined representing a number of data access operations within a predetermined time period for a data storage capacity of the DSD. Storage areas of the DSD are configured as one of at least the first area type and the second area type based at least in part on the determined value.
