UGREEN CM777 M.2 NVMe/SATA SSD Enclosure (20Gbps, RGB, Space Gray)

The UGREEN CM777 is an external M.2 SSD enclosure that accepts both NVMe (M‑key) and SATA (B+M‑key) M.2 drives in 2230/2242/2260/2280 sizes. It connects via USB‑C using USB 3.2 Gen2×2 (up to 20 Gbps), providing a high‑speed external interface for laptops, desktops and other USB‑C devices without requiring an extra power adapter.

The unit features an aluminum body with RGB lighting, tool‑free drive installation and a thermal design aimed at stable sustained transfers. It supports TRIM, S.M.A.R.T. and UASP to help maintain SSD performance, and typically ships with a USB‑C cable for plug‑and‑play use across Windows, macOS and Linux.

Rated for drives up to 8 TB and driven by a modern USB‑to‑SSD bridge controller that enables the 20 Gbps mode, the CM777 is suitable for fast file transfers, backups and using an external NVMe as a portable high‑performance volume.
