UGREEN CM559 NVMe SATA SSD Enclosure with 20Gbps Speed

The UGREEN CM559 is a dual-protocol NVMe SSD enclosure that turns a spare M.2 drive into fast portable storage. Its USB 3.2 Gen 2x2 interface delivers up to 20Gbps, so large video files, backups and game libraries move quickly.

It supports both M.2 NVMe and M.2 SATA drives, so you don’t need separate cases for different SSDs. Supported capacity goes up to 8TB, which suits creators, students and professionals who carry big files.

Whether you’re backing up a project at the office or editing footage on location, this UGREEN SSD enclosure works with Windows, Linux, Android and iOS devices.

Key Features

• 20Gbps USB 3.2 Gen 2x2 interface: Large files transfer far faster than with standard USB enclosures, which saves time on backups and exports.

• Dual protocol support (NVMe and SATA): Use either an M.2 PCIe NVMe or an M.2 SATA SSD in the same enclosure, so you can reuse drives you already own.

• Wide M.2 compatibility: It fits M-Key and B+M Key NVMe drives and M+B Key SATA drives, in 2280, 2260, 2242 and 2230 sizes.

• Up to 8TB capacity: You can pair it with a high-capacity SSD for large libraries, project archives and game collections.

• Built-in cooling pad: It helps manage heat during long transfers, supporting steadier performance.

• UASP and TRIM support: UASP improves transfer efficiency, and TRIM helps keep SSD performance consistent over time.

• Auto sleep function: The drive can sleep when idle, which helps with power management.

Why Choose This UGREEN CM559 NVMe SSD Enclosure

If you have an M.2 SSD sitting unused, this enclosure turns it into an external drive without buying new storage. The dual-protocol design means it still works if you later switch between NVMe and SATA drives.

You get 20Gbps speed, a cooling pad and broad device support in one compact case. That makes it a practical choice for daily backups, file transfers and portable workflows. It also works across Windows, Linux, Android and iOS, so you can use one enclosure with your laptop and phone.

Best Use Cases

• Content creators: Move and edit large photo and video files on an external SSD.

• Students and professionals: Carry projects, backups and large documents between devices.

• Gamers: Keep extra game libraries on portable high-speed storage.

• Data backup: Repurpose an old M.2 SSD as a backup drive.
