optimized simultaneous copy to multiple local destinations

I want to create a copy of my NAS hosted media folder that is about 30TB. I have a bunch of 4-8TB local (most USB3, some SATA) disks, and I would like to copy these files to the various destinations maximizing space used and time required. Since I have a 10GBE network, I can read data far faster than I can write to any of the destinations, so multiple simultaneous file copies is required at the same time to maximize this activity. doing this manually is painful. trying to select the maximum number of files that can fit (but not go over) each destination is a pain. Any thoughts on a script or an app I can use to assist here is appreciated. I want to leave the files in their native format, so I am looking for a file copy, not block-based backup etc.
