The UR2D-B32 is a professional dual-bay U.2 SSD hardware RAID enclosure designed for high-speed, serviceable workstation storage.

Its USB 3.2 Gen 2x2 Type-C interface provides up to 20Gbps link bandwidth, while the integrated hardware RAID controller supports RAID 1, BIG, and JBOD without requiring RAID software.

Compared with compact M.2 enclosures, the UR2D-B32 offers front-access locking trays, dedicated power, active cooling, and a more serviceable U.2 platform for sustained professional workloads. It is ideal for video editing, CAD, virtualization, digital asset management, backup, and high-speed local storage.

Key Features

1. USB-C 20Gbps Connectivity

● USB 3.2 Gen 2x2 Type-C interface

● Up to 20Gbps on compatible host systems

● Backward compatible with USB 3.2 Gen 2 and Gen 1

● Works with Thunderbolt™ 3, 4, and 5 USB-C ports in USB mode

● Supports Windows, macOS, and Linux

Most Mac systems operate at up to 10Gbps because macOS does not natively support USB 3.2 Gen 2x2.

2. Dual U.2 and Optional M.2 NVMe Support

● Supports two U.2 SSDs

● Supports M.2 NVMe SSDs through optional Ubox Mini adapters

● Front-access drive installation

● Lockable all-metal drive trays

● Simplified drive replacement and maintenance

3. Hardware RAID Flexibility

The RAID controller operates independently of the host computer and requires no RAID management software.

Changing the RAID mode erases all data on both SSDs.

4. Intelligent Monitoring

Front-panel indicators provide clear status information for:

● Power

● Drive activity

● Drive failure

● RAID rebuild

● Alarm conditions

● Rebuild progress at 25%, 50%, 75%, and 100%

6. Professional Cooling and Power

● Aluminum enclosure

● All-metal drive trays

● Built-in 30mm fan

● High and Low fan-speed settings

● Dedicated 12V/4.2A, 50W power adapter

The active cooling design helps reduce heat buildup and maintain stable SSD performance during sustained workloads.

Performance Expectations

The UR2D-B32 provides up to 20Gbps of USB interface bandwidth. Actual transfer speed depends on the SSDs, RAID mode, host controller, file system, workload, and operating environment.

With suitable SSDs and a compatible USB 3.2 Gen 2x2 host, the enclosure is designed to operate close to the practical bandwidth available from the 20Gbps USB interface.

● RAID 1: Prioritizes data protection

● JBOD: Each SSD operates independently

● BIG: Combines capacity but does not provide striping or redundancy

Matched SSD models and capacities are recommended.

Benefits

UR2-B32 vs. UR2D-B32

Choose the UR2-B32 for portability and native M.2 NVMe support.

Choose the UR2D-B32 for U.2 SSDs, front-access serviceability, stronger thermal management, and workstation-class deployment.

Why U.2?

U.2 SSDs are widely used in professional and enterprise-oriented systems because their larger form factor, robust connectors, and thermal design are well suited to sustained workloads and serviceable storage environments.

Best Fit For

The UR2D-B32 is ideal for professionals who need high-speed, serviceable SSD storage with hardware RAID and reliable thermal management.

● Video editing and media production — Store, edit, transfer, and protect large video files and production assets.

● Photography and digital asset management — Import, organize, edit, and safeguard large RAW image libraries.

● CAD, 3D design, and engineering — Improve access to large project files, models, simulations, and technical data.

● Virtualization and software development — Run virtual machines, development environments, software builds, and large datasets.

● Professional backup — Use RAID 1 to maintain mirrored local storage for important business and project files.

● Workstation storage expansion — Add front-access U.2 storage with dedicated power, locking trays, and active cooling.

Important Notes

●  A USB 3.2 Gen 2x2 host port is required for up to 20Gbps operation.

●  Thunderbolt hosts connect through USB compatibility mode.

●  Most Mac systems operate at up to 10Gbps.

●  Hot-plug is not supported in BIG mode.

●  Changing the RAID mode erases all data.

●  Safely eject JBOD drives before removal.

●  Keep the enclosure powered on during RAID 1 rebuilding.

●  Pressing Mute silences the buzzer but does not clear the alarm condition.

Frequently Asked Questions

Q1: What RAID modes are supported?

A: RAID 1, BIG, and JBOD.

Q2: Is RAID software required?

A: No. RAID operation is managed by the integrated hardware controller.

Q3: Can M.2 NVMe SSDs be installed?

A: Yes. Optional Ubox Mini adapters are required.

Q4: What happens if one SSD fails in RAID 1?

A: The remaining SSD retains the mirrored data. After the failed SSD is replaced, the enclosure rebuilds the mirror and displays progress at 25%, 50%, 75%, and 100%.

Q5: Does changing RAID mode erase data?

A: Yes. Back up all important data before changing the RAID configuration.

Q6: Why is speed limited to 10Gbps on a Mac?

A: Most Mac systems do not support USB 3.2 Gen 2x2 and therefore connect at USB 3.2 Gen 2 speed.

Q7: Is the UR2D-B32 a Thunderbolt device?

A: No. It is a USB device that connects to Thunderbolt USB-C ports through USB compatibility mode.

Q8: Does it support hot-swap?

A: RAID 1 and JBOD support compatible hot-swap workflows. Hot-plug must not be used in BIG mode.

Performance test result for reference. The test result will vary depend on the test environment.
