Q:
Hey,
I was thinking of purchasing an external hard drive for my laptop for backup purposes. I'm looking for USB and 500GB or more.
Considering it's backup and I want it to be really portable, I'd prefer it not to have to be powered. What are the pros and cons of having it self-powered, such as by USB, versus having it powered by the mains? Does it run faster?
Not plugging it in to power is great when you're travelling -- on a plane, for example. I assume it is less prone to lightning/electrical issues.
