Areca ARC-8050U3-6 – 6-bay RAID system

Areca ARC-8050U3-6 handles four transfer standards via a single port: USB 2.0, USB 3.0, USB 3.1 and Thunderbolt 3

Backwards compatibility has usually meant making compromises. In the ARC-8050U3-6 RAID system, however, this does not apply. The ingenious storage box handles four transfer standards via a single connection: USB 2.0, USB 3.2 Gen1, USB 3.2 Gen2 and Thunderbolt 3. Depending on the host connection, the inexpensive compact tower thus achieves between 480 Mbps and 10 Gbps.

The system achieves the high transfer rate because it can be equipped with fast SAS disks (12 Gbps) on the drive side. Of course, cheaper SATA HDDs as well as SSDs can also be installed in the six "hot swap" capable slots.

As an OS-independent storage system, it can be installed without additional software or drivers. It supports RAID Level 0, 1, 10, 1E, 3, 5, 6, Single Disk or JBOD for the necessary security of the stored data. In addition, the ARC-8050U3 can optionally be equipped with a battery backup module. This protects the data in the cache memory in the case of an unexpected power failure. Its controller-level ROC hardware encryption manages all types of drives without compromising performance.

The user can configure and monitor the system directly via the LCD control panel or via the LAN port.

The compact storage cubes are suitable wherever large amounts of data need to be quickly available at individual workstations. This is particularly true for the media industry, for example in audio or video editing as well as photo composing. Since there must be no disturbing noises, the Areca engineers installed an intelligent cooling system in the ARC-8050U3-6. It continuously adapts to the ambient conditions by automatically regulating the speed of the brushless fan.
