Bigger disk in a Thunderbolt G-Raid 4 TB

I have a G-Raid 4TB with thunderbolt that i bought in 2013, is it possible to swap out the disks in this unit? Does it support bigger disks than the current 2 TB?

Yes it will support larger capacity drives. We sold a unit that was 12TB in the same enclosure.

Great! Thanks for the info.
