Hello All,
I just purchased one of the DPT controllers for use on a 15mbps ESDI drive
here in the office. I would be very interested to see if anybody else on
the net has been using the DPT contorller, and under what configuration.
Prior to using the DPT product I had the Adaptec 2322B ESDI controller,
but needed a 15mbps (not 10) for the new 780 megabyte harddisk. I decided
to give an intelegent harddisk controller a shot, and so far it appers to
be working very well. At present I am using the basic configuration of
512K of cache/buffer on the controller, but would like to hear of others
experiences with the board. I would also be interested to see if anybody
increased the onboard RAM, and how much improvement did the increased RAM
give you. I believe the price for the controller is fair, but the cost to
add RAM adds up real quick. So as the story goes, I wouldn't buy the
additional RAM unless the cost was justified...
