How to Determine if an Internal Hard Drive uses Air or Helium

 

An Internal Hard Drive can be made with Air or Helium.

Why fill a drive with helium?

There is less friction inside the drive when filled with helium. Helium is lighter than air. Thinner disks can be used inside the drive so more data can be saved. More disks also increases the transfer speed of the drive.
