Thunderbolt™ 3 to 12Gb/s SAS RAID Storage

The ARC-4050T3 series are Thunderbolt™3 expansion chassis with one PCIe 3.0 slot to fit a low profile adapter for high-performance 4K video editing and networking. By supporting Thunderbolt-compatible low profile PCIe adapters, the ARC-4050T3 expansion enables professionals to use high-performance PCIe adapters or RAID adapters on the lacking PCIe expansion MacBook Pro. Supported adapters include Areca 16Gbps Fibre Channel, 6Gb/s SAS Host as well as 12Gb/s SAS RAID controllers. Designed and leveraged with Areca’ existing high performance internal PCIe adapters, Areca’s family of Thunderbolt 3 products provide a perfect outside-the-box solution for your 4K deployments.

ARC-4050T3 series connect with high performance RAID solution to deliver true hardware RAID for the video editor working with real time multi-stream HD and 4K workflows. It runs efficiently without disruption or major drops in performance to meet the requirements of 4K data workflow. The Thunderbolt 3 Solution from Areca provides the supreme performance so quick that it allows 4K video at the same time while daisy chaining storages devices and doing a simultaneous 4K in/output file transfers.

With dual 12Gb/s SAS ports and dual 40Gbps Thunderbolt 3 ports configurations, the ARC-4108T3 is an ideal solution to connect a high- performance RAID controller with JBOD enclosure for users looking to achieve the highest I/O and data throughput for 4K workflows.

With dual 16Gbps Fibre Channel ports and dual 40Gbps Thunderbolt 3 ports configurations, the ARC-4607T3 is an ideal solution to connect a high-speed Fibre Channel SAN for users looking to achieve the highest I/O and data throughput for 4K workflows.
