Edit addition: After further observation, the large improvement was due to AMD Radeon Settings, not the SSD. The improvement was accomplished on my Radeon HD 7990 video cards by increasing voltage to +10% and reducing VRAM speed to 150 MHz instead of 1500 (for heat reduction). The increased voltage is needed to keep the GPUs running at 950 MHz without intermittently throttling back to 501 MHz. I am sorry for the bum dope, but I do admit my mistakes.
I recently decided to mirror my SSD to a SSHD for use with my four Radeon HD 7990 video cards (eight GPUs). Everything else remained the same as before with the SSD (except that I defragged the SSHD). I did not anticipate a performance change, but I saw decreased PPD as can be seen in the Daily Project Scores histogram at Free DC, photo: https://ibb.co/VB6WHm0 . The difference is about 500,000 PPD (3,300,000 vs 2,800,000). I changed back to the SSD on 13 October. The computer is a dedicated cruncher and is used for no other purposes. I waited a few days because I did not want to prematurely say that I observed a difference of near 15%.
The rig has 8 GPUs on four PCIe x 1 risers, an Intel i5 7600 (4 cores without hyperthreading) at 4.0GHz, and 16GB DDR4 2666MHz RAM on an ASUS B250 Mining Expert motherboard. I run 3 work units per GPU simultaneously or 24 WU at a time with the 4 core processor.
I don't know what it can do for a computer with a single video card, but it seems worth trying a $50 SSD if yours has a rotating hard drive.
