    I have 2 Seagate 4TB External HD with Thunderbolt.
    Currently I am set up as follows:

    iMac > thunderbolt cable > 4TB HD
    > thunderbolt cable > 4TB HD

    Looking to Daisy Chain them:

    iMac > thunderbolt cable > 4TB HD > thunderbolt cable > 4TB HD

    Any performance issues/changes?
    Can I still transfer files directly between HD's?

    Thank you!

    Daisy chaining them works just fine

    I run mine like this:

    rMBP > Thunderbolt display > Thunderbolt display > LaCie 20TB > LaCie 6TB > LaCie 4TB

    I haven't had any performance issues and I transfer data regularly to all 3 drives.

    Thank you.

    Curious - if we can daisy chain the Thunderbolt HD's, what is the advantage of having a Thunderbolt Hub?

    There is no such thing. Thunderbolt 'hubs' offer one TB IN and one TB OUT for daisy chaining. And in addition to that USB, sound etc.

    Thunderbolt, like Firewire before it, and SCSI before that....are designed for changing devices. That is different from USB where hubs offer multiple ports in parallel.

    The Apple Thunderbolt Display acts as a "hub" for non-TB ports. Inside the ATD different types of ports (ethernet, USB, FW) are multiplexed onto the Thunderbolt bus. But from the Thunderbolt bus perspective, the ATD is just one device.
