I have a Firewire port on the back of my computer, and two Firewire
enclosures. You can do this with them. The "X" means the second
connector on the second drive is not used.

+----------+
Computer ----------| Firewire |
| Drive |
+---| #1 |
| +----------+

| +----------+
+---| Firewire |
| Drive |
X----| #2 |
+----------+

My experience suggests the daisy chain connectors are "active buffered".
If my computer talks to drive #1, I get higher bandwidth than drive #2.

There seems to be a bit of a bottleneck, for packets that go in and out
of drive #1, on their way to #2. YMMV.

I don't have a third enclosure, to daisy chain a third one :-)
