Internal hard drives are significantly cheaper than external hard drives, so this is my question: is there a reason that I would really need to use an external hard drive for backing up data instead of an internal one? Wouldn't it be acceptable for me to just use an internal HDD for this purpose?
I could keep the internal hard drive in its own place when I'm not using it. When I want to read or write to it I just turn off the computer, open the case, and put the drive in. Then when I'm done I can take it back out. The only thing I see about external drives is that they make it slightly easier to connect to the computer; also, laptop users usually can't have two drives inside. But opening the case really isn't that hard, and the other thing only applies to laptops.
