12Bay Thunderbolt 3 & USB 3.2 Gen2 Hardware RAID


Flexibility to Unleash your Creativity

The latest ARC-8050T3U Series is not only capable of Thunderbolt 3 with 40 Gbps, but also works with computers via USB 3.2 Gen2 (3.1) and backwards compatible with USB 3.0 as well.


Equipped with dual Thunderbolt 3 ports for connecting to any Thunderbolt 3-enabled host and offers an additional Thunderbolt 3 port for daisy-chaining other peripherals, while also supplying power for quick notebook charging. The ARC-8050T3U also sports a full sized DisplayPort 1.4 video output on its rear, allowing for a quick and easy 8K 30Hz display setup


A built-in USB device controller is automatically enabled when the ARC-8050T3U is plugged in a USB 3.2 Gen2 Type-C (3.1) computer port, a well as backwards compatible with USB 3.2 Gen1, 3.0, 2.0 host ports. In this condition, the ARC-8050T3U Thunderbolt 3 port behaves exactly like a typical USB-C 3.2 Gen 2-enabled connector.


Unparalleled Performance

ARC-8050T3U series offers the most powerfull and reliable  Thunderbolt™ 3 desktop Hardware RAID storage for both PC and Mac solutions. ARC-8050T3 incorporates an industry proven on-board dual core 1.2Ghz RAID-On-Chip and with 2GB DDR3-1866 memory to deliver true high performance hardware RAID protection against drive failure. This combination helps to provide a high performance storage device perfect for the video editor working with Real time multi-stream HD and 4K, 6K and 8K workflows.


Enterprise Class Data Availability & Security

The ARC-8050T3 supports Hardware RAID 5 for uninterrupted data availability in a single drive failure event or  RAID 6 for dual drive failure safeguard. Active hot-spare drive assignment to automatcally use and instantly begin the rebuilding process and Hot-Swappable drive bays provides zero downtime to swap drives during a drive failure event. 


Intelligent power On/Off function powers the ARC-8050T3-12 unit in unison with the host computer during startup and shut-down for extra level of data integrity.


Controller-level hardware encryption manages all drives attached to the ARC-8050T3U-6/6M/8/12 for higher levels of data security and protection without impacting performance.


Built-In 12Gb SAS Expansion Port

The ARC-8050T3U-6, 6M and 12bay solutions offer a external 12Gb SAS (MiniSAS/SFF-8644) Port for users who want to add additional cost effective 12Gb SAS Expander JBOD storage units and maximize their storage capacity up to 512 drives total! Also allows you to convert any existing 12G SAS expander storage to be used with any Thunderbolt 3 host.
