The wife just bought a new DSLR 18MP camera. So, we are going to need some new hard drives for storage and backup. I do not want to store them on my main HD in order not to clog things up. What are my best options if I want to have to 2 back-ups? I was thinking one portable USB hard drive and one regular hard drive in an external case? Any thoughts? Wanna kill these ads? We can help!
