2 firewire perphs, 1 port

[MightyOne]

Can I simultaneously use two 2 firewire devices through one port?

I would like to record through the MOTU 828, while reading and writing from an external 7200 firewire drive--that's how it's done right?
Do I need a hub?
Can I daisy chain?
Is this possible?

Thanks.

Go the route of the hub.
