The dd_rescue tool will try to make the best of both worlds here:

  The two block sizes are a performance optimization. Large block sizes
  result in superior performance, but in case of errors, you want to
  try to salvage every single sector. So hardbs is best be set to the
  hardware sector size (most often 512 bytes) and softbs to a large value,
  such as the default 16k.
