Is this 2 3TB drives that are set up as Raid 1? So you only have 3TB usable storage?

  • The Drives do not arrive formatted as RAID 1... so when you plug it in you instantly get full use. You must reformat to use as a mirror drive. Which is not difficult. Although there is no CD or manual in the box as stated on Apple's website. You must download both from LaCie. So far very happy with my purchase.

    Hi Kathryn,
    The 6 TB version comes with 2 3TB drives. With Raid 0 (stripe), you'll get 6TB of storage and with Raid 1 (mirror), you'll get 3TB of storage.
    The 8 TB version comes with 2 4TB drives. With Raid 0 (stripe), you'll get 8TB of storage and with Raid 1 (mirror), you'll get 4TB of storage.

    Raid 0, striped, provides fast read and write times but relies on both drives to keep working.
    Raid 1, mirrored, has slower write times but if one drive fails, the second will still hold your files.

  • it depends on the one you are looking at if it is the 6Tb yes, but you can also put it in raid 0
