    I got a Caldigit Thunderbolt dock and daisy chained a Blackmagic Multidock from it with a Samsun 840 pro 512G drive in the BM. The BM dock is a SATA II device.

    I tested the BM directly connected to my imac and speeds are:
    345MB/s - 380MB/s W/R

    When I daisy chain off the Caldigit (with nothing else in the Caldigit) I get
    250MB/s - 325MB/s W/R

    Any one else finding slowdowns when daisy chaining TB devices??

    You are sharing bandwidth and with the cal digit dock having video it's probably using a lot of bandwidth.

    I currently have this chain:
    Macmini (2011) -> Caldigit dock -> Areca TB drive array -> displayport monitor

    I have an 840 Pro (128 GB) in the Areca array as a pass-through drive, and it registers 385w/495r. I have not tested it without the Caldigit dock in the chain, however.
