The drive came formatted with the exFAT file system but for testing, we reformatted the drive to NTFS. To test the drive we used an Asus ThunderboltEX3 add-in card.
Test System;
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.
