Quiet operation and heat management

To reduce noise during operation, the LaCie d2’s built-in stand features vibration-dampening rubber feet. Additionally, the LaCie d2’s metal casing dissipates heat from the drive, allowing for noiseless, fan-free cooling. Since LaCie's unique design draws heat away from the internal hard drive, the external casing will be warm to the touch after extended use.

The LaCie d2’s specially constructed exterior can prolong the life of its hard drive via the fan-free cooling system. To protect the hard drive from external forces, the LaCie d2 also includes rubber anti-shock disk mounts within the enclosure.

Position and stacking

Always make certain to place the LaCie d2 on a flat, even surface that can support the heat output and airflow of a professional hard drive enclosure. For proper heat dissipation, the LaCie d2 is designed to stand on its stand. DO NOT place the enclosure on its side when it is powered on.

The LaCie d2 is does not support stacking. Doing so poses a severe risk that it will fall. DO NOT stack other drives, enclosures, or equipment on top of the LaCie d2.

The warranty for your LaCie d2 will be voided if you:

  • Stack the LaCie d2 enclosure on another device.
  • Stack other drives, enclosures, or equipment on top of the LaCie d2.
