Overview

The UR2-B32A is a compact dual-slot NVMe SSD RAID enclosure purpose-built for users who need high-speed solid-state storage on systems with USB Type-A connectivity. It accommodates two NVMe M.2 SSDs and features a USB 3.2 Gen2x2 Type-C interface that delivers data transfer rates up to 20 Gbps when used with the USB-C cable. For legacy setups, it offers backward compatibility with USB 3.0 Type-A ports at 5 Gbps speeds, using a second USB cable for power input to ensure stable operation. Designed with hardware RAID support, the UR2-B32A allows flexible drive configurations (mirror, JBOD, or span) to prioritize data redundancy or performance as needed. A built-in high-quality cooling fan and aluminum housing provide active thermal management, maintaining optimal SSD performance even under heavy workloads. This versatile enclosure works seamlessly across modern USB-C laptops and older USB-A desktops alike, offering a technically robust solution for expanding storage, safeguarding data, and accelerating workflows.

Benefits

 

• Plug-and-Play NVMe Expansion for Legacy Systems: The UR2-B32A brings NVMe SSD technology to older PCs and workstations that only have USB Type-A ports. Users can significantly upgrade storage speed and capacity without opening their computer or installing internal cards. By leveraging the enclosure’s backward-compatible USB 3.0 connection, an aging system can utilize fast NVMe storage externally, extending its useful life while maintaining easy setup.

 

• High-Speed Data Throughput: When connected via USB-C to a Gen2x2 port, the enclosure unlocks extreme transfer speeds (up to 20 Gbps), enabling rapid read/write performance for data-intensive tasks. This is ideal for activities like 4K/8K video editing, large media file transfers, gaming libraries, or scientific data analysis, where throughput directly impacts productivity. Even over a standard USB 3.0 Type-A link, the device delivers up to ~5 Gbps (significantly faster than external SATA drives), ensuring you get the best performance possible on any host.

 

• Data Redundancy and Security: In RAID-1 mode, the UR2-B32A provides real-time mirroring of data between the two SSDs, so if one drive fails, the other retains an intact copy. This redundancy is valuable for backup of critical files, project archives, or irreplaceable data on systems lacking other redundancy. The robust aluminum enclosure and fan cooling further protect your SSDs by preventing overheating, thereby enhancing data reliability during long backup sessions or continuous use.

 

• Flexible Storage Configuration: With its support for three RAID/JBOD modes, this device adapts to your needs. Use JBOD mode to access each SSD independently (for example, using one drive as a bootable media and another for data). BIG mode allows the two SSDs to be combined sequentially into one large virtual drive, useful for storing very large datasets or media collections that exceed a single SSD’s capacity. This flexibility means one enclosure can serve multiple purposes – from scratch disk to backup vault – as your requirements change.

 

• Consistent Performance with Cooling: Unlike typical fanless single-SSD enclosures, the UR2-B32A’s active cooling design keeps NVMe drives at optimal temperatures under heavy load. By preventing thermal throttling, it ensures that transfer speeds remain steady during prolonged operations such as cloning disks, streaming high-bitrate video, or running virtual machines from the external RAID. The low-noise fan and efficient airflow design maintain a quiet environment, making it suitable for offices, studios, or home use where both performance and low acoustics are important.

 

• Versatile Power and Portability: The dual-cable power system offers great convenience for different scenarios. In an office or home setup, the AC adapter can provide dedicated power so the enclosure doesn’t draw heavily on the host. For portable use or fieldwork, the UR2-B32A can be entirely bus-powered via USB, leveraging two USB ports from a laptop (one for data + power, one for additional power) with no need for a wall outlet. This makes it an excellent choice for on-site photo/video shoots, outdoor research, or travel, where you need high-capacity high-speed storage off-grid. The durable build is designed to handle frequent transport, and hot-swap trays mean drives can be quickly inserted or removed for off-site data rotation.

 

Applications

 

• Legacy PC and Workstation Upgrades: Ideal for adding high-speed storage to older desktops or laptops that lack USB-C ports. For example, a photographer with a USB3.0-only computer can use the UR2-B32A to work with NVMe SSDs, dramatically improving external storage performance for editing and backup tasks without having to replace the entire system.

 

• External High-Speed Scratch Disk: Suited for modern content creation and engineering workflows, the enclosure can serve as a portable scratch disk or project drive. Connect it via USB-C 20 Gbps to a compatible workstation for tasks like 4K video editing, CAD rendering, or large dataset processing. 

 

• Redundant Backup and Archiving: For users seeking a reliable backup solution, the UR2-B32A in RAID-1 mirror mode acts as an external redundant drive that safeguards data by writing it to two SSDs simultaneously. This isvaluable for small business data archives, home office backups, or storing important project files. The device can be scheduled as a backup target (for example, using third-party software or OS tools) to regularly clone important folders. If one SSD fails, data remains accessible from the other, providing peace of mind. Additionally, the enclosure’s BIG mode can be used to create a single large archive volume for infrequently accessed cold storage (e.g. a combined 2×2TB SSD for 4TB of backup capacity).

 

 

• On-Site Data Ingestion and Field Work: The UR2-B32A is a strong choice for field use. Media professionals can bring it on shoots or remote locations to back up camera footage or drone videos on the spot, using a laptop to copy data onto the dual-SSD RAID (with the fan keeping those SSDs cool during large transfers). Researchers or engineers conducting on-site data collection (e.g. recording sensor data, logging, etc.) can similarly use the device to store data reliably in real time. Even without readily available AC power, a laptop or battery pack can power the unit via the USB Type-C 5V input. This ensures that critical data is captured and mirrored immediately, reducing the risk of loss before returning to base.

 

• Mixed-Platform Work Environments: In offices or studios where both Macs and PCs are in use, the UR2-B32A acts as a universal storage solution. Its plug-and-play compatibility with Windows, macOS, and Linux means a team can easily share large files or project data across different systems by simply moving the enclosure between workstations. For example, a video editing team might use it to shuttle a project from a Windows desktop to a MacBook Pro – the USB interface ensures no special adapters or network transfers are needed. The device’s robust construction also makes it suitable for frequent handling in these collaborative environments, and the fast interface minimizes wait times when copying files between machines.

 

 

Each of these scenarios highlights the UR2-B32A’s technical strengths: its ability to deliver NVMe SSD performance in a flexible, RAID-protected external solution, and its compatibility with both cutting-edge and legacy interfaces. This makes it a unique and valuable tool for users looking to enhance storage capabilities while maintaining data safety and broad connectivity. The UR2-B32A effectively bridges the gap between old and new, ensuring that no matter your setup, you can take full advantage of modern high-speed NVMe storage technology.
