   Specifically, it is a 2:1 interleave MFM controller, ST-506 
presentation to the system bus.  We are running this drive controller 
with 80 meg drives and have no problems with it.  The drives, on the 
other hand, are taking a terrible beating at the hands of the news feeds.

   Depending on the access speed of your drive and the computer, you 
might want to look into replacing the -WA2 with the WD-1006-WA2, which 
will allow 1:1 interleaving of the hard drive.  We are looking at this 
for our host computer as a way to increase speed for the network news 
decompressions, as well as increasing the system RAM.
