Muggle: this is a standard Blu-ray optical disc. It is capable of storing up to 100gb of information, which [according to Google] roughly translates into one or more movies (depending on the video quality), 28,000 songs, 30,000 photos, or 67.8 million pages of text.

Wizard: all of that in this tiny disc!? What is this? Magic?

Muggle: nah bitch, that's physics.

Wizard: gasp physics! What a strange name for muggle-magic.
