I suggest you make a large ram drive and use it for all your processing.
It will take a bit of time to copy all your subs and calibration frames to the ram drive before you start your workflow, and it will take even more time to copy the final project file back out for archival, but it will be hugely worth it because I/O will be dramatically faster than with the SSDs.
Not sure that's really covered in the benchmark, but it will certainly speed up your actual work.
