The UGREEN CM777 (25665) M.2 NVMe/SATA SSD Enclosure offers high-speed portable storage through a USB 3.2 Gen 2×2 Type-C interface rated at up to 20Gbps. Powered by the RTL9220 controller, it supports both NVMe PCIe and SATA M.2 SSDs, providing a versatile solution for file transfers, external backups and storage upgrades.
With support for 2230, 2242, 2260 and 2280 SSD sizes, theoretical capacity support up to 8TB and an aluminum thermal design, the CM777 is suitable for home, office and professional storage applications. Explore the UGREEN CM777 price in Bangladesh at IT Source.
When upgrading a computer, an existing M.2 SSD can remain useful even after it has been removed from the system. The UGREEN CM777 allows compatible internal SSDs to be reused as portable external storage rather than left unused.
Its main advantage is dual-protocol compatibility. The enclosure accepts supported M.2 NVMe PCIe and M.2 SATA SSDs, making it a flexible option for computer technicians, laptop owners and users who work with different storage formats.
The USB-C connection makes it convenient to access files on compatible computers, while its aluminum housing and thermal pad help manage heat generated during SSD operation.
The enclosure does not contain built-in storage. A compatible M.2 SSD must be installed separately.
The UGREEN CM777 features a USB Type-C interface supporting USB 3.2 Gen 2×2 with up to 20Gbps theoretical bandwidth.
This provides high-bandwidth connectivity for transferring large video files, high-resolution photographs, software archives and other demanding data collections.
With a compatible NVMe SSD and suitable computer, users can benefit from faster external storage access than a conventional 5Gbps USB enclosure.
Achieving the full interface speed requires a USB 3.2 Gen 2×2-compatible host port and cable. Many USB-C ports, including some Thunderbolt and USB4 ports, do not support this particular 20Gbps mode. Actual performance depends on the SSD and connected computer.
The CM777 supports compatible M.2 NVMe PCIe SSDs and M.2 SATA SSDs, allowing one enclosure to accommodate two commonly used SSD protocols.
Its internal connection supports PCIe 3.0 x4 operation for compatible NVMe drives, while SATA SSD operation is limited by the SATA interface, with SATA III offering up to 6Gbps theoretical bandwidth.
This versatility is particularly useful for technicians who need to access drives removed from different laptop or desktop computers.
Supported drives must use the appropriate M.2 form factor and protocol. The enclosure does not directly support 2.5-inch SATA drives, mSATA SSDs or conventional hard disks.
The UGREEN CM777 accommodates M.2 SSD sizes 2230, 2242, 2260 and 2280.
This allows users to select a suitable drive from several common SSD form factors, including compact 2230 models and widely used 2280 SSDs.
The product specification lists theoretical capacity support up to 8TB, while supplier documentation reports testing with drives up to 4TB.
Users planning to install a very high-capacity SSD should confirm compatibility with their exact drive model. Actual available storage depends on the installed SSD and file-system formatting.
The CM777 uses a Realtek RTL9220 controller for communication between the installed SSD and the connected computer.
The enclosure supports UASP, which can improve USB storage command handling on compatible systems, and TRIM, which assists supported SSDs in managing unused data blocks.
These features make the enclosure useful for regular file transfers, portable working storage and backup operations.
The product documentation also lists electrical protection features, including over-current and short-circuit protection. The effectiveness of storage-management functions depends on the SSD, operating system and connected hardware.
The UGREEN CM777 features an aluminum alloy housing designed to assist with heat dissipation.
A high-thermal-conductivity silicone pad helps transfer heat away from the installed SSD toward the enclosure housing.
This passive cooling arrangement is useful during sustained file transfers, when NVMe SSDs can become warm and potentially reduce performance if operating temperatures become excessive.
The CM777 also includes an indicator light for storage activity and operating status. For reliable cooling, install the thermal material correctly and avoid covering the enclosure during intensive workloads.
The CM777 supports driver-free operation on compatible Windows, macOS and Linux computers, making it convenient to connect and access an installed SSD.
Its USB-powered design removes the need for a separate external power adapter under supported operating conditions.
The enclosure also features automatic sleep functionality after approximately 15 minutes of inactivity, helping reduce unnecessary SSD activity when the drive is not being used.
It is suitable for portable backups, accessing existing SSD data and transferring files between compatible systems. New SSDs may require initialization and formatting before use; formatting an existing drive can erase its stored files.
The UGREEN CM777 is suitable for IT technicians, computer repair professionals, photographers, content creators, students and office users who need convenient external SSD storage.
It is particularly useful for users who own different M.2 NVMe and SATA drives and want a single compatible enclosure for file transfers, backups or storage reuse.
For users whose computers do not support USB 3.2 Gen 2×2, the enclosure can still be useful at a supported lower USB speed, but its full 20Gbps bandwidth will not be available.
IT Source offers computer storage accessories and connectivity products for customers in Bangladesh. The UGREEN CM777 (25665) provides a flexible way to convert a compatible M.2 NVMe or SATA SSD into external USB-C storage.
Contact IT Source to confirm the current product price, availability, drive compatibility and applicable local warranty before ordering.
Yes. It supports compatible M.2 NVMe PCIe and M.2 SATA SSDs in 2230, 2242, 2260 and 2280 sizes.
No. Full 20Gbps operation requires a USB 3.2 Gen 2×2-compatible computer port and cable. Other USB-C connections may operate at lower speeds.
The CM777 lists theoretical support up to 8TB, with supplier documentation reporting testing up to 4TB. Compatibility with a specific high-capacity SSD should be confirmed before purchase.
