  Um, wouldn't that be only a little better than a normal RLL drive?  I have
  been looking into getting a RLL controller for some time now, and the
  Perstor advertises 90% storage increase with a 2:1 interleave.  If you were
  to get something like an Adaptec or DTC 1:1 interleave board, you could
  get aproximately 120mb (if only a few hard errors).  Then with those, you 
  can get upwards of 650 kb/s transfer rate.  Given that the ARLL board has
  that many problems getting up to the expected 90% storage increase, I would
  (am going to) consider getting the RLL drive because there won't be many
  errors due to the board, and the high transfer rate.  

  just some thoughts,
  lee
