Stripe's block size.

Multiple of a drive's sector.
  Blocks often sector, cluster, or multiple of these.

  Sectors of a file are distributed round robin fashion across disks.
    Allows for parallel concurrent access of the multiple sectors.

    Allows for parallel concurrent access of different files.

Byte (or bit) size access.
  Bytes of a file are distributed round robin across disks.
    Advantageous for quick error checking and recovery.

    Actually not good with smaller files, 
      less likely to get high parallel access.

  Requires advanced data parsing.

  Requires synchronized disk spindles.

  Drive must still read and store data in sector or cluster sized blocks.

    Best when reading very large sequential files such as uncompressed video.
