    I’ve been using a Drobo 2nd gen with my wife's 2007 iMac. The iMac has two Firewire ports:

    - an 800 port connected to my Drobo (which is used for data)
    - a 400 port connected to an old 500 GB Ext HD (used as a scratch drive for Final Cut Pro)

    This has worked fine for my purposes. I’m considering moving up to a new 27" i7 iMac. However, I believe the new iMac only has one 800 FW port.

    My question is: if I daisychain my scratch disk through the Drobo FW ports (the Drobo has 2 FW 800 ports) via a 400 to 800 adapter, will I get the same kind of performance I need for Final Cut Pro?

    Yes unless both disks are accessed at the same time when the port in iMac will be the bottleneck

    Thanks for the info. That's good to know. I'm getting a 400/800 adapter this week so I should be able to try it on the old iMac before I pull the trigger on the new one.
