I was just looking through a flyer annoucing disk drive upgrades
for DN3xx, DN5xx, and DN3000 nodes. The technicals specs lists
the new 190Mb for the DN560/570/580 as having a transfer rate of
only .625 Mb/sec -- slower than the .806 Mb/sec transfer rate of
the 70Mb drive on the DN300/320/330 and *much* slower than the
10.0 Mb/sec rate of the DN3000 disks. Is this a misprint? Why would
the high-end workstations have the slowest disk drives and the
low-end workstations have the fastest disks?
