Aluminum enclosure converts M.2 SATA SSDs (30, 42, 60, 80 mm) into USB 3.0 portable storage with UASP support
Color Black
External Interface USB 3.0
The StarTech SM2NGFFMBU33 converts a M.2 SATA solid-state drive into a bus-powered USB 3.0 external drive. It accepts common M.2 lengths of 30, 42, 60 and 80 mm and supports SATA I, II and III interfaces. The aluminium housing acts as a heatsink and fits in a pocket. UASP support on compatible hosts can raise transfer efficiency by up to 70 percent over standard USB 3.0.
Suits users who want to reuse an existing M.2 SATA SSD as portable storage across Windows, macOS and Linux without drivers. Not for buyers who need NVMe speeds or an enclosure that accepts PCIe-based M.2 drives. Also unsuitable if the host only offers USB 2.0 and the workflow demands the full 5 Gbps link rate.
The external interface is USB 3.0 at 5 Gbps with UASP protocol support, which can deliver up to 70 percent faster transfers than bulk-only transport on a UASP-enabled host. This single specification determines whether the enclosure can saturate a SATA III SSD.

Other versions of this model
With a UASP-enabled host you can reach up to 70% faster transfers than standard USB 3.0, though the SATA III drive inside caps sustained throughput at 6 Gbps.
Yes, the 5 Gbps USB 3.0 link is slower than the drive's 6 Gbps SATA III ceiling, so the enclosure's port becomes the bottleneck.
The enclosure accepts 30 mm, 42 mm, 60 mm and 80 mm M.2 SATA modules and includes a screw kit for securing them.
