# Is it OK to leave an external drive plugged into my Mac all the time?

Yes. External drives are designed to stay connected, and macOS lets them idle or sleep when they aren't in use. For a desktop Mac, an always-connected drive is the normal setup — and it's how Storage Studio expects the fast drive to be used, so moved apps and folders are always reachable.

A few sensible habits:

- Keep it somewhere ventilated, not under papers or in direct sun.
- Use a surge-protected power strip if the drive has its own power adapter.
- Eject before unplugging it.

If you carry a MacBook around, you can unplug the drive when you leave — see [taking your MacBook out without the drive](https://storagestudio.us/faq/external-drives/can-i-take-my-macbook-out-without-the-drive).
