Hello again! I was hoping some of you could give me a more focused narrative on external hard drives for the most recent version of the 13" rMBP with 4GB RAM and 128 GB storage. It's more or less for backing up files, word documents, etc. I don't use any pressing applications: no Photoshop, Illustrator, video gaming, or music software. The extent to which I use the laptop includes basic necessities such as Spotify, Word, Excel, Outlook, and web browsing. I know it may seem like overkill, but I don't want to risk losing my work again after my recent "accident." Any advice guys? Google's search results are definitively scattered and I have yet to locate any sound advice on external HDs and I hesitate talking to anyone at local stores. I really appreciate it in advance.
