1. A data storage device, comprising:
one or more disks;
a write mechanism configured to write data to disk surfaces of the one or more disks, the write mechanism comprising an actuator arm assembly that includes heads suspended over the disk surfaces; and
one or more processing devices, individually or in combination, configured to:
encode data into a plurality of logic blocks;
assign at least some of the logic blocks to a plurality of containers of two or more different container sizes, wherein the containers each comprise one or more distributed sectors; and
output a write signal to the write mechanism to write the at least some of the logic blocks in an interleaved pattern on the disk surfaces in accordance with the assigning of the at least some of the logic blocks to the plurality of containers.
