The Adaptec 2400A can be queried through a utility known as raidutil. Part
of the output of raidutil -L all is:

d0b2t0d0 50 MHz 100 MB/sec wide
d0b3t0d0 10 MHz 100 MB/sec wide
Notice the 10 MHz above. I'm wondering why it is 10, and the others are 50.
Checking around the net, I can't find any examples where these four values
differ from the above.
