G-RAID DUAL DRIVE 6TB not recognized - model number not found

Hello! I just bought a G-RAID Dual Drive 6TB and would really like to switch it to RAID 1.
Problem ist that I do not seem to be able to find the correct software to change the RAID status.
I tried all I could find (including G-Technology RAID Configuration Utility_v1_0 for MAC, as I am using High Sierra on a 2012 MacBook Pro)

In addition I cannot find the model number listed anywhere on the G-TECHNOLOGY website. It is GRADEB60002BAB.
The drive does have 2 FW 800-ports, one eSATA and one USB 2.0 (mini) - also specifications I cannot find anywhere on the website of G-TECHNOLOGY.

Help is greatly appreciated!

… or is this drive no “real” RAID at all but only a simplyfied version that cannot be changed to RAID 1?
