It's too small text files, which saves only when you saving any shader or applying shader to image (last used shader). It's can't make any bad impact to your SSD. Usually SSD vendors make warranty for a 3-5 years for writing 20 GB/day. I can't imagine situation, when you will write 20 MB of shaders / day.
We fixed this in version 1.1. Also "Shaders" folder with templates and config moved to Documents folder, because plugin can't take enough rights for working in Program Files folder.
