# How much storage do I need on a new Mac?

It depends on what you keep locally rather than on any single number:

- **Light use** (web, documents, most files in the cloud) — the base storage is usually workable, with care.
- **Photos and music libraries kept locally** — choose more, or plan an external drive for libraries.
- **Video editing, development, games, virtual machines** — these grow fast; more internal storage or a fast external SSD is close to essential.

Remember that macOS, updates, caches and snapshots need headroom too, and internal storage can't be upgraded later on Apple silicon. Many people buy a mid-size internal drive and keep big, less urgent data on an external SSD.
