MB307U-1VB_USB4 to U.2/U.3 NVMe SSD External Adapter

Professional-Grade NVMe SSD Access in a Compact Form Factor

The EZ-Adapter Ex MB307U-1VB is a high-performance USB4 to U.2/U.3 SSD adapter designed for media professionals, IT engineers, and field operators who require quick and reliable access to 2.5" U.2 or U.3 NVMe SSDs. Housed in a compact and lightweight enclosure, the MB307U-1VB delivers blazing-fast data transfer speeds of up to 40Gbps* through a USB4 Gen3x2 interface while supporting Thunderbolt 4, USB 3.2, and USB 2.0 connections. Whether in a post-production studio, on-location set, or edge computing environment, the MB307U-1VB empowers users to work efficiently without compromise.
USB4-Level Speed with Broad Interface Compatibility

The MB307U-1VB utilizes the advanced USB4 interface, enabling real-world data transfer rates of up to 3800MB/s when connected to a native USB4 host. It also supports Thunderbolt™ 3 & 4, with speeds reaching up to 2800MB/s, ensuring high-speed access even on professional workstations and Macs. Additionally, backward compatibility with USB 3.2 Gen 2x2, Gen 1, and USB 2.0 guarantees seamless integration with a wide range of devices. This flexibility makes the MB307U-1VB a powerful tool for handling high-throughput NVMe SSDs across various platforms without worrying about cable or port limitations.

Note: Actual transfer speed depends on the SSD performance, system configuration, and interface protocol of the connected device.
Optimized Compatibility with Enterprise SSD Trays

Engineered with flexibility in mind, the MB307U-1VB features a tool-less slot design that accommodates both bare U.2/U.3 SSDs and third-party drive trays from leading server manufacturers like Dell, HP, and Supermicro. This universal compatibility eliminates the need to disassemble SSDs from their existing carriers, saving time and reducing wear. The plug-and-play interface enables seamless drive swaps with over 10,000 insertion cycles, making it an ideal solution for system testing, drive cloning, data recovery, and multi-device workflows.
Precision-Crafted Aluminum Cooling Plate

To maintain optimal performance during sustained data transfers, the MB307U-1VB integrates a center-mounted aluminum cooling plate that directly covers the high-speed data controller inside the adapter. This passive heatsink design enhances thermal dissipation from internal IC components, ensuring stable operation under heavy load.
Independent Power Design for Greater Control

To ensure stable power delivery for high-performance U.2/U.3 SSDs, the MB307U-1VB includes a 12V/2.5A (30W) external power adapter. This setup provides sufficient output for most enterprise-grade SSDs on the market, eliminating concerns about power draw limitations from bus-powered USB ports. By separating data and power paths, this design also helps reduce system-side power strain and maintains reliable SSD operation during intensive workloads.
Designed for Mobility

Crafted for on-the-go use without sacrificing robustness, the MB307U-1VB blends lightweight ABS with sturdy aluminum. Enjoy easy portability alongside enhanced structural integrity and cooling efficiency for the perfect balance.
Streamline 12K Footage Offloading and On-the-Go Editing

For content creators working with high-resolution workflows, such as offloading 12K Blackmagic URSA Mini Pro footage or editing directly from U.2 SSDs, the MB307U-1VB offers a fast and portable solution. By eliminating the need to disassemble OEM trays, it simplifies post-production processes, allowing seamless data access in the field or studio.
IT Labs, Forensic Analysis, and Edge Computing Ready

The MB307U-1VB serves as a versatile PCIe NVMe SSD media reader for IT diagnostics, edge computing nodes, and forensic data collection environments. With broad U.2/U.3 compatibility and a high-performance USB 4 interface, it’s an essential tool for developers, system integrators, and technicians working with NVMe drives across a wide range of platforms.

Featuring hot-swap capability, the MB307U-1VB allows drives to be added, replaced, or removed without shutting down the system—minimizing downtime in mission-critical workflows. For added safety and to reduce wear during periods of non-use, the integrated power switch lets users cut power to the drive instantly.
Pair it with the M.2 to U.2 NVMe SSD adapter (EZConvert MB705M2P-B)

Converting your M.2 NVMe SSD into U.2 NVMe SSD with the EZConvert MB705M2P-B adapter offers tool-less SSD installation and comes with a large heatsink designed explicitly for high-speed M.2 NVMe SSDs. The MB705M2P-B uses a bridge connector to link the M.2 NVMe SSD, ensuring that the gold fingers of the M.2 NVMe SSD are protected from damage during insertion and removal. This makes it an ideal solution for users who frequently swap M.2 NVMe SSDs.
Pair it with the ToughArmor MB601M2K-1B M.2 NVMe SSD mobile rack

The ToughArmor MB601M2K-1B mobile rack supports PCIe 4.0 transfer speeds up to 64Gbps and fits into a computer system's standard 3.5" drive bay. Pair it with EZ-Adapter Ex MB307U-1VB gives you both PCIe 4.0 transfer speed and on-the-go convenience.
