It supports 40Gbps bi-directional bandwidth per channel with Thunderbolt 3 port. In short, it's rather disappointing and frustrating that Dell doesn't seem to be inclined to support a TB3 upgrade, especially for one of their most widely used high-end workstations.Īnyway, I recently discovered a TB3 AIC made by ASRock (follow the link). Adding insult to injury, this will limit the speed to Thunderbolt 2 specifications. It turned out to be a less than ideal situation because I also needed to buy a Thunderbolt 2 cable connecting to the older Dell AIC on one side and a TB 3 to TB 2 Adapter on the other. I own and operate a Dell Precision dual processor T7910 as well and have been looking for a Thunderbolt 3 add-in card (AIC) since the original configuration only includes Thunderbolt 2.īecause I needed a high-speed interface between external disk drives and my workstation for data backup, I chose and purchased an Akitio (now Other World Computing) Thunder3 RAID Station, which features the new Thunderbolt 3 connectivity.
