On my recent build I used an SSD for the C drive which holds the operating system and the main Poser program.  My runtimes are on a seperate conventional hard drive but this is also accelrated using a second SSD plugged into the mSata port on the motherboard.  

The launch of Poser is indeed much faster which should be down to the SSD as I am using Windows 7 exactly the same as the system it replaces.  The library is also much quicker thanks to the acceleration.  

As you say it does nothing to change the render time and as Laurie stated the time saving is minimal in the great scheme of things.  That said, it does make Poser a pelasure to use, but then it always was.

 

 

I use Poser 13 on Windows 11 - For Scene set up I use a Geekcom A5 -  Ryzen 9 5900HX, with 64 gig ram and 3 TB  storage, mini PC with final rendering done on normal sized desktop using an AMD Ryzen Threadipper 1950X CPU, Corsair Hydro H100i CPU cooler, 3XS EVGA GTX 1080i SC with 11g Ram, 4 X 16gig Corsair DDR4 Ram and a Corsair RM 100 PSU .   The desktop is in a remote location with rendering done via Queue Manager which gives me a clearer desktop and quieter computer room.
