I want to update this thread to explain what I've done to eliminate the issue I was having.

I wasn't able to add another internal SSD hard drive as the expansion slot was already in use so I purchased a SATA Seagate 2GB hard drive and mounted that in the PC. I installed all my BB and Realband programs on the internal SATA drive and run them from there. Now everything works fine with no issues on rendering files and I've eliminated some external clutter around my DAW.

Rendering times are now consistent and take around 10-15 seconds running the programs from the internal SATA drive.

Thanks to all of you who gave me some ideas to work through this!
