The EZ-Adapter Ex MB931U-1VB provides SMB, power users, and media professionals the quickest and easiest way to access their enterprise-level U.2 PCIe NVMe SSDs. The EZ-Adapter Ex utilizes a 10Gb/s USB 3.2 Gen 2 interface and backward compatible with the previous USB 2.0 interface for best system compatibility. The tool-less SSD installation design allows users to transfer large files from multiple U.2 drives to any computer through a USB connection without having NVMe support on the computer end.

Professional Adapter for Enterprise U.2 Drives

The benefits of using U.2 NVMe SSDs are fast IOPS, high storage capacity, long lifespan, end to end path protection (ETEP), and power loss protection (PLP). However, accessing U.2 drive required NVMe host and specific cables, making the data transfer between the systems almost impossible. With EZ-Adapter Ex MB931U-1VB, simply connect the U.2 SSD to the EZ-Adapter and then plug the USB type A or C connector into the system to start the data transfer immediately.


The tool-less drive installation allows the MB931U-1VB to swap multiple U.2 drives within seconds and making the process seamlessly.


For video professionals who film 12K footage with Blackmagic URSA Mini Pro 12K camera and U.2 SSD, the EZ-Adapter MB931U-1VB is an excellent USB media reader that lets you quickly access your U.2 media drives in seconds.

Superior Performance

To fully utilize the power of the U.2 PCIe NVMe SSD, the EZ-Adapter Ex uses the USB 3.2 Gen 2 interface that can provide transfer speeds up to 10Gbp/s, giving you the ability to back up large data files or store 4K/5K/8K videos in seconds. A 12V power supply is included to ensure enough power is provided for the power-hungry U.2 SSD.


The exposed U.2 SSD from the enclosure allows full passive heat dissipation to optimize cooling performance.

Compact for Portable

The MB931U-1VB has been engineered for mobility but does not compromise functionality and durability. The EZ-Adapter Ex is made out of durable ABS plastic with a smooth finish that will not damage other equipment when placed in your carry-on bag. The compact design allows the EZ-Adapter Ex to be carried without taking too much space.

Ultimate Compatibility

The MB931U-1VB comes with USB type C to C and type C to A cables and backward compatible with the previous USB 2.0 to support new and legacy PC/MAC systems that use different types of USB ports. The EZ-Adapter Ex is a true plug and play external enclosure with no drivers required.

LED Indications

The EZ-Adapter Ex is equipped with a LED indicator that shows the drive power and activity. The individual slide-switch power button allows users to power off the SSD when not used to extend the drive’s lifespan and conserves electricity.

Product Review:

By Eric Smith

January 29, 2021

"This is the type of enclosure that is extremely useful if you have a high-volume of NVMe SSDs you need to connect. If you work at an IT helpdesk, in a lab, do video production, or just have to move a lot of data using a sneakernet, this is one of those tools that may seem expensive at first but becomes extremely useful."
