External drives · Choosing a drive
Can I use two external drives as fast drives at the same time?
Short answer: No. Storage Studio uses one active fast drive at a time. A second drive can hold a verified spare copy with Backup Drive, or become the new working drive with Transfer Drive.
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.
