1. A data storage device comprising:
storage media comprising a first set of memory blocks having a first performance level and a second set of memory blocks having a second performance level, the first performance level being better than the second performance level; and
control circuitry 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;
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, wherein performance level is read speed, write speed, or endurance;
save the partition settings to the storage media; and then
creating the first partition and the second partition.
