For anyone using Windows 10, this seems to be the better RAMDisk software at the moment since it is updated regularly, but most importantly this is the only one which is co-signed by Microsoft Windows and therefore works with SecureBoot and other newer Windows security features.

Regarding exFAT. I had initially trialled that some months ago specifically to see if it could speedup Chromium even more from a filesystem perspective and it did seem promising from a performance perspective. However, I had repeat problems with Chromium profiles becoming corrupt which I normally had never experienced. Anyway, I decided to give exFAT with Chromium another trial right now and so far so good. I've done a bunch of browsing and mounted/unmounted the RAMDisk a handful of times and so far no profile corruption which is good news.

I will trial some more with exFAT before I decide to move my daily use Chromium profile over to exFAT. I am beginning to think that it was more of a bad combination with CCleaner, RAMDisk, and exFAT. I think that junk/temp file cleaning from CCleaner had some sort of negative conflict with my Chromium profile specifically on exFAT filesystem. I'll continue to test further to see where and when the corruption occurs.
