My new (mid 2014) macbook pro has 8 GB of RAM and 120 GB of storage. I've installed windows through bootcamp (storage is divided 100 GB for mac HD and 20 GB for bootcamp), and wand to install arcGIS now. However, I was told that my memory is not enough for working with heavy geodata. In order to solve this I thought about using an external solid-state drive with 256 GB for increasing storage space. Is this a good solution? would it work?
