Abstract
A method of writing to a data storage drive having a first media partition having a first write speed and a second media partition having a second write speed slower than the first write speed includes mapping a plurality of logical block addresses (LBAs) to a plurality of physical block addresses (PBAs) of the first media partition, and writing to the plurality of LBAs mapped to the PBAs of the first media partition. It is determined whether the first media partition is at or above a predetermined storage level, and, when the first media partition is at or above the predetermined storage level, data is moved moving data from the first media partition to a plurality of PBAs in the second media partition, and mapping of LBAs and PBAs in the data storage device is updated.
