Dual Hdd Mac?

[waranger]

I have a friend looking for a laptop that can handle a huge amount of storage. He is aware of using an external drive but wants to keep the package as "all-in-one". So, I recommended getting a laptop with dual bays. This was all fine and dandy until someone got him wound around the idea of "needing" a "Mac". Now I am on the hunt for a Mac that utilizes dual HDD bays. Or, if I can find some software that will reformat "Mac" files/programs into "PC" (my friend is having video edited by a third party that uses a "Mac").

You can't add another HDD/SSD to retina models but in older models(with optical drives),it's possible.You can remove the ODD and add a HDD/SSD
