Hello, I have been following this group for a long time and just ordered a refurb base nmp. I obviously need more storage and was curious the best, most affordable options you are using. I was thinking a Lacie thunderbolt 2 disk drive (knowing that tb2 at 20gbs won't work with a 7200 disk drive). It's affordable and has a lot of space. I take it most of you are keeping your OS and software on the 256gb flash and storing all of your media on the external drive? Does this work well? I am just a consumer with a lot of images and will use it to make movies and media projects for our family. Should I just see if Apple will upgrade my refurb computer for the same cost as ordering the config? Like a 512 or 1tb? Sorry for all the questions, I am just looking for a good opinion. Thanks!
