Orico 3559C3 5-bay drive enclosure USB 3.1 Gen 2 10Gbps 16TB per bay 64TB max

Five-bay USB 3.1 Gen 2 DAS enclosure

The Orico 3559C3 is a five-bay direct-attached storage enclosure that connects over USB 3.1 Gen 2 at up to 10Gbps. It accepts both 2.5 and 3.5 inch SATA drives, with each bay supporting up to 16TB for a total of 64TB. The aluminium chassis includes a built-in 150W power supply and an 80mm silent fan for active cooling. It is aimed at professionals who need high-capacity external storage without a dedicated NAS.

Upgrade from single-drive docks

Moving from a single-bay dock or a USB 3.0 enclosure adds four additional drive slots and doubles the interface bandwidth to 10Gbps. The jump is worth it when workloads outgrow one drive, when RAID arrays are required on macOS, or when hot-swapping multiple drives saves downtime. Intelligent sleep mode reduces wear and power draw during idle periods.

Fits a workstation desk

The unit measures 264.8 by 137.0 by 200.7mm and weighs 5kg, so it sits on a desk or shelf without rack rails. Two USB 3.1 Gen 2 Type-C cables are supplied for host connection, and the 150W adapter powers all five drives simultaneously. Screw-in trays secure each drive for transport. It works with Windows, macOS and Linux without extra drivers. Buyers who need hardware RAID offload or more than five bays should look elsewhere.
