The Areca ARC-8050T3U-6 is a desktop RAID storage solution engineered for professionals working with large media files and demanding data workflows.
This 6-bay enclosure combines high-speed Thunderbolt 3 connectivity with enterprise-class hardware RAID capabilities, enabling reliable data management without consuming host system CPU resources.
Connectivity and Performance
The system features dual Thunderbolt 3 ports capable of 40 Gbps data transfer speeds, which is twice the bandwidth of Thunderbolt 2 and four times faster than USB 3.2 Gen 2.
An additional Thunderbolt 3 port enables daisy-chaining of up to six devices, while the DisplayPort 1.4 output supports 8K 30Hz display configurations.
When connected via USB-C to a non-Thunderbolt host, the enclosure automatically activates its internal USB device controller, functioning as a standard USB 3.2 Gen 2 device.
Hardware RAID Architecture
At the core of the ARC-8050T3U-6 is a dual-core Broadcom SAS3108 RAID-on-Chip (ROC) processor running at 1.2 GHz, delivering true hardware RAID functionality independent of the host system's CPU.
The controller includes 2GB of DDR3-1866 SDRAM with ECC protection and supports PCI Express 3.0 with 8.0 GT/s throughput and 1GB/s per-lane bandwidth.
This architecture offloads RAID processing from the host system, reducing CPU load compared to software RAID solutions and maintaining performance during array rebuilds.
Storage Capacity and Drive Support
The enclosure accommodates six 3.5-inch or 2.5-inch hard drives or solid-state drives via 12Gb/s SAS or 6Gb/s SATA connections.
Maximum capacity reaches 96TB with six 16TB drives or 108TB with six 18TB drives, providing substantial storage for professional workflows.
The system supports multiple RAID configurations including RAID 0, 1, 10, 3, 5, 6, 30, 50, 60, single disk mode, and JBOD (Just a Bunch of Disks).
Advanced RAID Features
The ARC-8050T3U-6 offers online RAID level and stripe size migration, allowing users to reconfigure arrays without data loss or downtime.
Global and local hot spare support enables automatic failover in the event of drive failure, while disk scrubbing and array verification scheduling maintain data integrity.
Additional capabilities include multiple SSD/HDD disk cloning, SSD automatic monitor cloning (AMC), and Self-Encrypting Drive (SED) function support for enhanced security.
Thermal Management and Power
A single 2700 RPM cooling fan exhausts heat from the rear of the enclosure, maintaining optimal operating temperatures for sustained performance.
The system draws 180W of power, supplied by an internal power supply unit.
Physical Design and Portability
The desktop form factor measures 4.84 x 8.45 x 9.11 inches (146 x 255 x 290 mm) and weighs 13.2 lbs (6.0 kg), making it suitable for studio and desktop environments.
The enclosure features an SFF-8644 expansion port with 2-lane support for additional connectivity options.
Operating System Compatibility
The ARC-8050T3U-6 supports macOS 10.12 or later and Windows 8/10 or later when connected via Thunderbolt 3.
When operating in USB mode, the enclosure is OS-independent, functioning with any system that supports USB 3.2 Gen 2 connectivity.
M1 Apple computers require specific driver installation for full Thunderbolt 3 functionality.
