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. |
|
Encryption software is only available via download and is not available
in Russia. |
|
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. |
|
The 4-disk version ships with a single PSU, and is therefore not
hot-swappable. Purchase an additional PSU Kit to ensure full
redundancy. |
|
When referring to drive capacity, one gigabyte, or GB, equals one
billion bytes and one terabyte, or TB, equals one thousand billion bytes.
Your computers 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. |
