Comments * Hot swapping will result in data loss in a RAID 0 array.
** 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 RAID mode, RAID configuration, and disk capacity.
*** To achieve full interface bandwidth, connect the product to a Thunderbolt 2 port on a computer or device.
▲▲ These measurements have been made under normal conditions, one meter/three feet from the front of the product. This value 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.
