Interleave refers to the spacing between consecutive sectors on a hard drive.
1:1 is the closest sectors can be placed, as this is a sequential layout.
Not all controllers can deal with this rate, and my have to let the disk spin
around once before getting the next sector.  A 1:1 controller can handle
this rate properly, giving the fastest possible access on the drive.  But
other controllers may work OPTIMALLY at interleaves of 1:2 or 1:3.  Depends
on your hardware.  Spinrite reports the optimal interleve for a system.
