SSD Installation Causes FPS Drop in Cinebench, Not in Ungine

post #1 of 3
Thread Starter 
I have a problem that I have not been able to find a solution for. I recently installed an old SSD from my laptop into my system. When I did my FPS in Cinebench OpenGL FPS dropped from ~78 to ~22. When I remove the SSD my frame rates go back up to 78. Neither the OS or the benchmark programs are being run from the SSD. I am not doing anything in the background, the SSD is just sitting there as far as I can tell.
Having the SSD installed does not change my Ungine benchmark at all, either in Valley or Heaven. It also does not change the CPU benchmark in Cinebench, just the OpenGL.

I have tried this over several reboots / power cycles and having the SSD installed seems to be the problem and it is only changing my Cinebench scores. It is consistent; Cinebench always drops down to ~22 FPS when the SSD is present, the Ungine benchmarks are not changed. Does anyone have any insight? Either what the problem is or what an SSD installation has to do with Cinebench but not Ungine's benchmarks?

fyi - the animation definitely stutters at one point and slows down significantly during the Cinebench OpenGL benchmark when the SSD is installed. Temps are consistent 65 - 70 across all configs / tests.

Seagate 1TB HDD
Seagate 500GB SSD 2.5'' installed in HAF-X front port

Edit: Sorry if I wasn't clear. The SSD/hybrid drive does not have the OS or the benchmark software on it. It is being used for storage and is not being accessed when I am running the benchmark software.

That Seagate "SSD" is actually a conventional HDD with a tiny SSD in it (4GB). I have one in a laptop as well, and it is admittedly decently fast, but it's no SSD. I'd just get an actual SSD, which are pretty cheap these days if you stick with <128GB capacities.

I have eliminated the possibility of a PSU problem. Same issue w/ 2 separate PSUs.

Any ideas would be welcome.
