Parallel copy folder from one source to two destinations possible?

[cinema4dme12]

Hi!
So I have the Donation Version of FFS and thought the parallel operations is what I needed, though I can't figure out what I am doing wrong.

Here's the task:
Copy one folder from one fast nvme SSD to two identical HDDs. I was thinking because the source drive is so much faster, it should be able to write the files to the destinations in parallel instead of sequential, speeding up the copying considerably... Is this possible?

I have two folder-pairs, source = the ssd, destination the two hdds. But FFS is first copying to the first drive, and after that is finished, copying to the second drive. Can this be done in parallel? I increased the parallel operations to 2 or 5 or 10, but no difference. The second HDD waits idly until the first folder pair is finished.

Am I doing something wrong or is this not possible?

Thanks!

Yeah, I wish it worked like that, but it doesn't. You would have to run two independent syncs, and disable the 'lock' files that FFS creates. You can then have a batch script that runs both of them.
