# How are Storage Studio's low-space warnings different from macOS's "disk almost full" alert?

macOS warns when you're already nearly out of room. Storage Studio tries to warn you **earlier and more usefully** by watching how fast space is going, not just how much is left.

- It weighs the rate against what you have and puts it as roughly **how many days of room** are left at this pace — so a big download on a roomy drive doesn't trigger anything, and a slow leak on a nearly full one does.
- It names the app the space went to when it can, hedges when it isn't sure, and says plainly when it can't tell.
- The red alert badge beside the bell appears only once your drive is at least 95% full, measured as a share of the drive rather than a fixed number of gigabytes.
- Every warning leads to **Emergency Space**, which picks the safest actions for the amount you need.
