1. A method of striping data from a host to a data storage device that includes a plurality of memory chips and a plurality of physical channels for communication of data between the host and the plurality of memory chips, each channel being operably connected to a different plurality of the memory chips, the method comprising:

  • determining a number of physical channels in the plurality of channels;

    for each of the determined physical channels, determining a number of memory chips operably connected to the channel;

    determining a first channel chunk size with which to write data to memory chips connected to separate channels;

    determining a chip chunk size with which to write data to different memory chips;

    segmenting, via the host, logically sequential data into first channel chunk size segments;

    segmenting, via the host, the first channel chunk size segments into chip chunk size segments;

    striping data to different channels of the data storage device in first channel chunk size units; and

    striping data in a first channel chuck sized segment to different memory chips connected to a channel in chip chunk size units.
