On the basis of the information provided so far (not withstanding some of it is still missing), the single simplest, cheapest and most effective thing you could do to speed up this processing would be to buy two SSDs and add them to your machine. Arrange for each of the sets of files to be written (or copied) to a different SSD and then run two separate processes, one for each set of files.

Done correctly, that would reduce your overall elapsed time to the runtime of the largest of the two datasets. Ie. If they were approximately equal, it would roughly half your processing time.
