4U, 24 bay Thunderbolt 3 Storage and PCIe Expansion

The Thunderbolt 3™ NA381TB3 is designed to give you higher capacity and even greater speeds. Features an expertly designed 4U 24-bay storage chassis with support of twenty-four hot-swappable drive trays. As each tray attached with 10TB HDD, total usable storage will come to 240 TB capacity. Additionally, through enclosure’s lightning-fast Thunderbolt™ 3 interface, the ultra large storage is ensured to have higher data transfer bandwidth of up to 2750 MB/s for all kinds of data archiving and real-time editing.

The Ideal Companion to Thunderbolt 3 Mac

Designed for use Thunderbolt™ 3 40Gbps high-bandwidth for the fastest ever data storage access and operation with multiple professional PCIe cards, which meant to be the perfect companion to your empowered Thunderbolt Mac or workstation.

Expansion for up to 3 PCIe Cards

Provides three PCIe 3.0 slots within the storage chassis that allow the users to make an easy expansion of varied specialty PCIe cards to the Thunderbolt 3 Mac. Except the necessary RAID adapter card to be added, the professionals can still choose to attach two more pro cards such as video capture, video transcoding, audio accelerator, network card and so on in the NA381TB3 to add extra performance to Thunderbolt Mac.

Dual Thunderbolt 3 Ports- The USB C That Does It all
By the two Thunderbolt™ 3 (USB-C) ports, users can have the first port to computer while the second port to daisy-chain of up to five additional Thunderbolt peripheral devices with two 4K displays or one 5K display being positioned at the very end of the chain. USB 3.1 Gen 2 (10Gbps) is also supported: connecting one USB device to the second port for application is available.
