Product information

Description

The StarTech.com SM21BMU31C3 is a compact M.2 SATA SSD enclosure that converts an M.2 NGFF SATA drive into a portable USB-C external storage device. It supports USB 3.1 Gen 2 (up to 10 Gbps) and UASP for improved transfer performance, fits M.2 drive lengths 2230, 2242, 2260 and 2280, and features a slim aluminium housing with ventilation holes for heat dissipation. The enclosure is compatible with laptops, tablets and desktops that have USB-C or Thunderbolt 3 ports and includes the required USB-C cable.

Advantages

This enclosure provides high-speed external access to a single M.2 SATA SSD via a USB 3.1 Gen 2 connection with UASP support, enabling up to 10 Gbps throughput on compatible hosts. Its lightweight aluminium construction offers protection while remaining pocket-sized for portability, and ventilation holes aid thermal management during operation. Broad compatibility with multiple M.2 lengths (2230/2242/2260/2280) makes it suitable for most common M.2 SATA drives.

Suitable for

  • Expanding storage capacity for laptops and tablets with USB-C or Thunderbolt 3 ports
  • Creating a portable external SSD from an M.2 SATA drive
  • Transferring large files between computers at high speed
  • Using an existing M.2 SATA SSD as a backup or transportable archive

How to use

Open the enclosure following the included instructions, insert a compatible M.2 SATA (NGFF) SSD of a supported length (2230/2242/2260/2280), secure the drive, then close the enclosure. Connect the enclosure to a host device using the supplied USB-C cable or a compatible USB-C/Thunderbolt 3 port. The drive is bus-powered; no external power adapter is required. For optimal transfer speeds, connect to a host that supports USB 3.1 Gen 2 and UASP.

Usage recommendations

When using the enclosure for sustained large transfers, place it on a flat surface with some airflow around it to aid heat dissipation. Ensure the host supports USB 3.1 Gen 2 and enable UASP where supported to achieve best performance. Handle the M.2 SSD carefully during installation and observe anti-static precautions.
