I have a 128gb 2013 MBA. I added a 256gb Transcend jetdrive. I want to run both Windows 10 as well as El Capitan. I'm debating about whether to use Boot Camp to have a dual boot system or running Fusion. In any case I'm looking for recommendations on partitioning the 2 drives. I'd probably run El Capitan most of the time, but do want access to run windows programs as well when needed.
