The Caching disk controllers from Distributed Processing Technology would
be an excellent choice for your application.  With one of these, the
average access time of your drives would approach .5 ms (not 5, but .5)
and with the cache being able to be set up to 4MB, it would turn that
300Mb drive into a real screamer.

They also offer an add on board for disk mirroring, and can support
any variation of ESDI, SCSI or MFM drive.  Since the definition of the
drive to the PC can be redefined from the actual physical drive config,
with the controller doing the translation, you can use virtually any drive.

The controller also does the error correction and bad tracking...

Give them a call.
