After playing around with the new Lightroom CC, I do love it! Simple and easy to use. Now that being said I get 100GB of cloud storage from Adobe. Instead of using the cloud storage I get from Adobe, would I be able to use my own personal NAS drive that i use as cloud storage? So that Lightroom CC automatically uploads to my personal cloud instead of Adobe's?
I believe Lightroom CC only works with Adobe's Cloud storage. You cannot use any other.
No you can't do anything like that. You can store local copies on your NAS drive if you want that would make access faster in Lightroom CC but you can't replace any other cloud storage for Adobe's. There is significant software running on the cloud side to make this all work that you can't reproduce yourself or using another service.
