    Would copying to a second dock slow me down?

    So it was time to upgrade all my drives, and i just purchased 11 new hard drives.

    As you can imagine, migrating the volume of data im migrating is going to be time consuming regardless. I'm trying to be as efficient as possible though. Im down to my last 6 disks. I'm dropping one in a dock, and copying from an internal. When im done with them all im going to swap them out.

    As we speak I have an 10tb drive in 1 dock being copied to from an internal. I have a second dock. If i hooked it up and started copying from a different internal drive to that dock, would I hit any type of bandwidth limit/throttle problem due to bus speeds?

    Theyre internal sata drives and they'd be going to the docks over USB 3.

    Dont want to hook it up and start it if its just gonna cut my currently going transfer speed in half or something.

    The bandwidth of USB 3 is high enough that 2 drives should not saturate it.

    Note you you could always start a copy to the 2nd drive and check to see if the transfer speed to the 1st drive is being reduced. If it is, then you could simply stop the 2nd copy.

    In addition, note that many systems have multiple root hubs. For instance, my desktop has both Intel and Asmedia USB hubs. If you connect each drive to a separate root hub, you should see full bandwidth available to each one, although as noted before, I doubt that would be necessary.

    this is what I had assumed, but i wasnt completely sure. Thank you for the confirm.

    that being said, my pc (or the controller) doesnt seem to care for 2 of the same dock being attached so it seems its not an option anyhow.

    I had considered connecting it to my other PC, then shooting it over the network - but i imagine it would saturate my network entirely and id prefer not to lock down all my bandwidth for a good 20+ hours per drive lol.
