operating system exclusive ssd

[Plank]

well i have two ssd's but since windows allways gets corrupt and crashes with me i wondered if there was a simple way of guaranteeing that only the operating system were on one of the ssd's and all new files to the other one. so i dont have to lose all my stuff again when im reformating. i have configured the storage setting to save evrything to the 500gig one but they still go to the windows one.

like for example installing the wifi driver automaticly puts it into the windows ssd
