okay not an expert, but most systems using these drives used interleaving of
sectors(because there was no way the system was fast enough to handle the
data), the IBM PC used a factor of 6. The machine the device would not know
what to do with 30MB/s of data if you produce it. i doubt any machine having
such a drive would benefit from more than 4MB/s and producing data faster
than the machine expects can cause timing errors, that were not noticed when
the machine was new. i guess after the device is made.. yo u will have to
spend more time slowing it down than trying to get it faster.

Hi
As far as I know, all PC hard disk interfaces had at least
a one sector buffer. This is unlike the floppy interface
that did byte for byte DMA.
