Hard drives are made out of tiny electromagnetic platters that spin at 4200, 5400, 7200 and even 10,000 rotations per minute. It’s amazing that this works at all. Here is a video of a hard drive in motion. Remember, this is where all your digital photos, movies, emails, documents, etc are stored – so back up your data often!
