How Much Storage Does the Average Computer Actually Use?

Ask what a typical computer holds and you'll get an average. Averages are close to useless here because personal storage is heavily skewed: most people sit well under 500 GB, a minority hold several terabytes of photos and video, and a very small group holds tens of terabytes.

Why the shape matters

For a backup provider, the distribution decides economics; for a customer, it decides which plan is honest. Publishing a plan sized for the median while quietly discouraging the tail is a well-worn trick, and we would rather price by segment than pretend the tail doesn't exist.

How to estimate your own

Check used space on every disk you own, including external drives you haven't connected in a while, and add roughly 20% for a year of growth. That number, not an industry average, is the one to price against.
