The Areca ARC-8050T3U-12E – 312TB is a high-capacity 12-bay desktop RAID storage enclosure designed for professional workflows requiring fast, reliable access to large datasets.
It combines Thunderbolt 3 and USB 3.2 Gen 2 interfaces with hardware RAID processing to deliver up to 40 Gbps transfer speeds, supporting demanding applications in video editing, audio production, and data archiving.
Connectivity and Expansion
Dual Thunderbolt 3 ports connect to compatible hosts, with a third port for daisy-chaining up to six devices.
A full-size DisplayPort enables direct monitoring of RAID status and array health on an external display up to 8K 30Hz.
USB 3.2 Gen 2 compatibility ensures broad device support without Thunderbolt.
RAID Controller and Performance
The enclosure features a tri-mode dual-core ARM A15 1.6GHz RAID-on-Chip (ROC) with 8GB DDR4-2666 SDRAM cache and ECC protection.
It supports 12 x 12Gb/s SAS or 6Gb/s SATA drives, pre-populated with 12 x 26TB 7200rpm enterprise drives for 312TB total capacity.
Hardware RAID offloads processing from the host CPU, enabling efficient array rebuilds and protection against drive failures.
Thermal Management and Power
Dual 2700rpm cooling fans exhaust heat from the rear to maintain optimal drive temperatures during sustained loads.
A 400W internal power supply provides stable operation, with optional Battery Backup Module (BBM) ARC-6120BAT021-T3 for data protection during outages.
Operating System Compatibility
Thunderbolt 3 mode supports macOS 10.12 or later and Windows 8/10 or later.
USB mode is OS-independent, broadening deployment options across platforms.
Physical Design and Use Cases
Measuring 8.1 x 12.2 x 11.4 inches (206 x 310 x 290 mm) and weighing 20.8 lbs (9.5 kg) empty, it suits desktop environments.
Ideal for content creators handling 4K/8K video, photographers managing large RAW libraries, and enterprises needing portable high-capacity storage.
