Why Do Pen Drives Have Two Holes? It’s Not Just for Design

Kokila Chokkanathan
If you’ve ever noticed two holes on a pen drive, you might have thought they were just for aesthetics. In reality, these holes serve practical purposes.

1. The Larger Hole – For Keychains and Lanyards

  • The bigger hole is usually designed to attach your pen drive to a keychain, lanyard, or strap.
  • This ensures that your USB drive doesn’t get lost easily and can be carried around conveniently.
2. The Smaller Hole – Indicator or Safety

The smaller hole often serves one of these purposes:

  • Activity Indicator Light: Some pen drives have a tiny LED inside, and the hole lets the light shine through to indicate:
    • Data transfer in progress
    • Device connected to the computer
  • Security / Locking Hole: On some models, the small hole can be used to attach a tiny lock or clip, especially in workplaces to prevent theft.
Bonus: Why Both Are Useful

  • Combining the keychain hole and indicator hole makes pen drives practical, portable, and safer to use.
  • While manufacturers sometimes design them for style, utility is the main reason.
💡 Pro Tip: Always use the keychain hole—losing a pen drive with all your data is far worse than just misplacing a small USB stick!
