    I am running Windows 10 in a Parallels VM on a MacBook Pro (16-inch, 2019).
    Which is the FASTEST way to copy a large amount of data from INSIDE the Windows 10 VM to an external drive?
    Would an external THUNDERBOLT 3 SSD drive (formatted as NTFS) be the best, i.e., fastest solution?

    I've not tested, but I imagine that would be orders of magnitude better than say using OneDrive within the VM or migrating to the Mac itself first. IDK for sure if it'll matter or not, but I'd set the RAM to 8 Gb for the VM so there's room for the OS to work plus the transfer.

    The Windows VM has 32 GB (while the MacBook Pro has 64 GB of physical memory). The VM also features 6 CPUs.
    However, there are two possible copy modes:
    1. Mac Finder or another Mac app does the copying
    2. Windows File Explorer or another Windows app does the copying
    Of course, the first copy mode is better because it is more efficient as a native process than an emulated process in the Windows VM.
