I have used an SSD from Corsair for well over a year with the Poser program installed on it and content on a traditional Hard Drive with an M3 SSD for acceleration.  I have seen none of the problems you have described and there is a definite speed advantage at some points such as start up.

 

That said a when I was doing the research a couple of the reviews susgested that OCZ do not have a solid history of relaibility.  The Vertex SSDs in particular seem to have a been problematic. 

If you do a google search on OCZ relaibility you will see a few sites such as Tom's hardware that have more details.

You might like to try another make before you give up on SSDs entirely.

 

 

 

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.
