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.
