Introduction: Centralize, Protect, and Expand Your Storage

In a world where digital files are increasing in size and importance, your storage solution should be more than just space—it should be fast, reliable, and secure. Whether you’re a content creator working with high-resolution video, a business archiving records, or a tech enthusiast building a backup system, you need an enclosure that offers both speed and redundancy.

The UGREEN CM381 Dual Bay 2.5″ RAID Enclosure is the perfect solution.

With support for RAID 0 and RAID 1, USB 3.1 Gen 2 speeds of up to 10Gbps, and room for two 2.5” drives, this enclosure is compact yet powerful. It gives you the flexibility to increase speed (RAID 0), mirror data for redundancy (RAID 1), or manage each drive individually (JBOD/SPAN). Designed with an aluminum casing and tool-free drive installation, it is ideal for those who want professional functionality in a user-friendly format.

Now available at Phonex Technologies Kenya, the CM381 helps you centralize your digital life—securely and efficiently.

USB 3.1 Gen 2: Up to 10Gbps Transfer Rate

With USB 3.1 Gen 2, the CM381 offers double the speed of traditional USB 3.0, allowing transfer rates of up to 10Gbps—ideal for:

• Transferring 4K and 8K video footage

• Editing files directly from external drives

• Quick backups of large project folders

• Reducing bottlenecks when working on the move

And thanks to UASP (USB Attached SCSI Protocol) support, the enclosure delivers significantly faster read/write speeds and reduced CPU usage compared to traditional USB connections.

Four RAID Modes: Tailor It to Your Needs

UGREEN’s CM381 supports multiple RAID configurations. Choose the one that suits your data strategy:

• RAID 0 (Striping): Combine both drives into a single large volume with improved speed

• RAID 1 (Mirroring): Duplicate data across both drives for redundancy

• JBOD (Just a Bunch Of Disks): Manage each drive independently

• SPAN (Linear Mode): Combine the drives into a single extended volume (concatenation)

Whether your priority is performance, data protection, or storage flexibility, the CM381 adapts.

• Brands like Samsung, Seagate, Western Digital, Crucial, Kingston, SanDisk, etc.

With support for up to 4TB per drive, you can configure a total of 8TB in this compact enclosure.
