Let me see...
My 1 Tera external is called TITAN, in all caps because caps are awesome. You can guess the reason for the name.
My identical twin 4 gig flash drives are Force and Diplomacy, because they're siblings, yet so very different.
My 500 gig portable HD that's the size of my wallet is called Freelancer; it's fast, maneuverable, and independent.
My BEASTLY 15 gig USB 3.0 flash drive that's made out of frugging RUBBER is called Corsair. Because it's a pirate. arr.
And my Zune HD is named Alexi, because that's a sexy name.
Then there's my friend's 1 Tera external, named The Fridge... because if you're not storing games in the fridge, you're doing something wrong.
