Do I have to use RAID or can it be used as a straight 6 TB drive?

    Inside are two SATA drives.

    You use Apple Disk Utility to set up in 1 of 3 possible configurations:
    - 2 separate 4TB drives
    - combine both drives into 1 8TB RAID-0 array optimized for performance - both drives are striped and made to look like one drive
    - combine both drives into 1 4TB RAID-1 array, optimized for safety - one drive is a mirror of the other

    This is all up to how the user configures the device.

  • This drive uses either two 3TB or two 4TB drives to achieve 6 or 8TB capacity. So you'd have to use RAID 0 to get 6TB from the twin 3TB drive model. RAID 0 will boost your speed (read/write half the data to either drive at the same time), but that is where it could be dangerous. With only half the data on either drive, if one drives fails, you loose the data on both. RAID 1 mirrors the data (copies it to both drives) so you have a built in level of protection. The cost of this is capacity. The 6TB model yields 3TB storage, and the 8TB model yields 4TB storage.
