   12 # Multiple sector I/O. a feature of most modern IDE hard drives,
   13 # permitting the transfer of multiple sectors per I/O interrupt,
   14 # rather than the usual one sector per interrupt.  When this feature
   15 # is enabled, it typically reduces operating system overhead for disk
   16 # I/O by 30-50%.  On many systems, it also provides increased non-DMA
   17 # data throughput of anywhere from 5% to 50%.  Some drives, however
   18 # (most notably the older WD Caviar series), seem to run slower with
   19 # multiple mode enabled. Under rare circumstances, such failures can
   20 # result in # massive filesystem corruption. USE WITH CAUTION AND BACKUP.
