We're testing out one of the low end DPT cards, but haven't had a chance
to really bang very hard on it. It's a bit slow, but it is the version
that has the 68000 processor on it.
The main drawback is that without support in the OS to control/configure
the array, you have to boot into DOS to replace a drive or set a hot spare
active...
