Going into mid-2018, CalDigit is looking to continue pushing its storage solutions to the next level. With much of their lineup now moved over to Thunderbolt 3, it was only fitting that their flagship four-bay RAID enclosure T4 made the move over as well.

Nearly four years ago, we had the T4 Thunderbolt 2 in the lab for testing. That unit produced 730 MB/s read and write via RAID 0 and 539 MB/s read 502 MB/s write via RAID 5 using Black Magic Disk Test and Thunderbolt 2. The new T4 RAID shares much of that design including the chassis, drive tray arrangement and cooling. What has changed is the interface, going from Thunderbolt 2 at 20Gbps to Thunderbolt 3 at 40GBps. CalDigit has also added the ability for the T4 RAID to charge your MacBook with 85 watts of power and it can also shoot pixels to a secondary display at 4K60 via the DP connection.
