Access Ultra-Fast NVMe Storage via 40Gbps USB4 with Thunderbolt 5 Compatibility

Turn your PCIe M.2 NVMe SSD into a fast and highly portable USB-C external storage solution. This NVMe enclosure supports USB4 (40Gbps), delivering read/write speeds up to 3,800 MB/s. Ideal for power users handling large media files, managing data across devices, or performing OS imaging, data recovery, and disk management.

Versatile USB-C & Thunderbolt Support

Built for current and next-gen storage, this USB4 enclosure connects M-Key or B+M Key M.2 NVMe SSDs (2230/2242/2260/2280) to USB4, Thunderbolt 5/4/3, or USB 3.2 hosts. It supports PCIe Gen 4x4 NVMe drives and offers native, driverless compatibility with Windows, macOS, and Linux. Seamless interoperability with USB-C and Thunderbolt systems makes it ideal for fast backups and high-volume data transfers.

Robust Heat Dissipation

The anodized aluminum housing features a heatsink-style cover design with a high-efficiency thermal pad to enable passive cooling during sustained workloads. The fanless construction allows for silent operation while maintaining consistent transfer rates during intensive tasks such as disk imaging or data capture.

Compact and Durable

The USB4 NVMe Enclosure's compact footprint fits comfortably in a technician's toolkit or laptop bag. The rugged aluminum housing not only helps with heat dissipation but also protects the SSD from physical damage during transport or deployment in demanding environments.
