So I have an old mac mini which acts as an iTunes, photos server, IP security cameras etc. If I go iPad only in the future I can use the NAS for my security camera's. But for file storage , photo's and apple music would an iPad only user just use iCloud. What are the storage options and management of music, films etc? I have terabytes of media which could sit on a NAS, could you access this much data without having a Mac?
