See full text

In one example, the disclosure is directed to a method comprising receiving, by a controller of a hard disk drive, a request to write a data block to a data storage platter of the hard disk drive. The data storage platter of the hard disk drive includes at least one random access zone and at least one sequential access zone. The controller determines a hinting value for the data block based on hinting information of the data block. The controller further determines, based at least in part on the hinting value, a location of the data storage platter of the hard disk at which to write the data block. The location includes one of the at least one random access zone or one of the at least one sequential access zone. The controller writes the data block at the location.
