Out of the box the four 4TB HGST Ultrastar 7K6000 (7,200rpm) drives in the G-Technology's G-Speed Shuttle are setup in a RAID 5 array. We tested it in this configuration and then tested each other RAID array that the unit supports; RAID 0, 1, 6 and 10.
To test the G-Speed Shuttle we used an Asus ThunderboltEX3 add-in card in our standard test rig: Intel Core i7-7700K with 16GB of DDR4-3200 RAM, Sapphire R9 390 Nitro and an Asus Prime Z270-A motherboard.
Thanks to Asus for their support with this. You can see more information on this card on the ASUS site, over HERE.
