# Can I use two external drives as fast drives at the same time?

No — Storage Studio works with one active fast drive at a time. Everything it moves for you goes to that drive, and that's the drive its shortcuts lead to.

A second drive still has uses:

- **Backup Drive** makes a full, verified copy of your working drive onto a second drive while the first stays active.
- **Transfer Drive** moves everything to a new drive and switches over to it when you upgrade.
- You can still copy files to any drive yourself with Data Parking or Finder — Storage Studio just won't manage them as relocated items.
