FAQ

Can I install any M.2 SSD in this enclosure?

Yes - the UGREEN CM777 supports standard M.2 sizes 2230, 2242, 2260 and 2280 and is compatible with both NVMe (M-Key or B+M Key) and SATA (B+M Key) drives. Just ensure you use a compatible drive format rather than mSATA.

Will I get full 20 Gbps speeds with my computer?

You can achieve up to 20 Gbps transfer speeds, but this depends on your host port supporting USB 3.2 Gen 2x2. If your system only supports USB 3.2 Gen 2 (10 Gbps) or USB-C with lower bandwidth, you will see correspondingly lower speeds.

Does it work with Mac, Linux or Android devices?

Yes - this enclosure offers broad compatibility across Windows, macOS, Linux and Android systems, making it ideal for use with laptops, desktops and even mobile devices.

Do I need to install a driver?

No driver is required - the tool-free design supports plug-and-play installation, so you simply insert your M.2 SSD, secure it and connect via USB-C for immediate use.
