UGREEN CM777 M.2 NVMe SSD Enclosure with 20Gbps USB-C

The UGREEN CM777 is an M.2 NVMe SSD enclosure that turns a spare M.2 SSD into fast external storage. It uses USB 3.2 Gen 2x2 over USB-C for speeds up to 20Gbps with NVMe drives, so large files copy quickly.

It also works with M.2 SATA SSDs at up to 6Gbps, so you can reuse an older drive. If you are looking for a reliable UGREEN SSD enclosure in Bangladesh, the CM777 suits backups, video projects and everyday file carrying.

The aluminum body and passive cooling help the drive stay stable during long transfers. It is powered over USB, so there is no adapter to carry.

Key Features

• 20Gbps USB 3.2 Gen 2x2 (NVMe): Large videos, project folders and backups transfer faster than on standard USB 3.0 cases, so you spend less time waiting.

• NVMe and SATA support: One enclosure fits both M.2 NVMe PCIe and M.2 SATA drives, so it keeps working if you change SSDs later.

• Up to 8TB capacity (theoretical, tested to 4TB): There is plenty of room to grow, and it has been tested with 4TB drives.

• Realtek RTL9220 controller: A proven bridge chip that supports UASP, TRIM and S.M.A.R.T. UASP improves transfer efficiency, TRIM helps keep SSD performance consistent, and S.M.A.R.T. lets you monitor drive health.

• Aluminum alloy body with thermal pad and passive cooling: The aluminum body and thermal pad draw heat away from the SSD, which supports stable speeds without fan noise.

• Auto sleep after 15 minutes: The drive powers down when idle, which saves power and reduces unnecessary wear.

• LED activity and status indicator: You can see at a glance when the drive is connected and transferring data.

• Supports 2230, 2242, 2260 and 2280 sizes: It fits most common M.2 SSDs.

• Compact 120 × 38 × 13mm design: It is easy to carry in a laptop bag or pocket.

Why Choose the UGREEN CM777 M.2 NVMe SSD Enclosure

The CM777 is a practical way to get more value from an M.2 SSD you already own, or to build portable storage with a new one. Instead of buying a fixed-capacity external drive, you choose the SSD size and speed that fit your budget.

For NVMe drives, the 20Gbps interface gives you real headroom for large file transfers. Because it also supports SATA M.2 drives, an older laptop SSD can become a useful backup drive.

Aluminum construction, passive cooling and a trusted Realtek controller make this a dependable choice for daily use. It works with Windows, macOS and Linux, so it is easy to share between computers.

Best Use Cases

• Content creators: Move large video and photo files between editing machines.

• Students and professionals: Carry documents, projects and backups in a compact case.

• Laptop upgrades: Reuse the old M.2 SSD from a laptop upgrade as external storage.

• Backups: Keep a fast copy of important files and system data.
