Quick Install Guide
* To achieve full interface bandwidth, connect the product to either a USB 3.0 or Thunderbolt 2 port on a computer or device.
** These transfer rates were achieved using AJA System Test when connected to a Mac computer via the Thunderbolt 2 interface. Actual data rates may vary depending on operating environment and other factors, such as chosen interface and disk capacity.
*** These transfer rates can be achieved by installing the LaCie d2 SSD Upgrade on a LaCie d2 Thunderbolt 2. The LaCie d2 SSD Upgrade is not compatible with the LaCie d2 USB 3.0.

▲▲ These measurements have been made under normal conditions, one meter/three feet from the front of the product. These values may vary with conditions and product configuration.

When referring to drive capacity, one gigabyte, or GB, equals one billion bytes and one terabyte, or TB, equals one thousand billion bytes. Your computer’s operating system may use a different standard of measurement and report a lower capacity. In addition, some of the listed capacity is used for formatting and other functions and will not be available for data storage.
