UGREEN CM645 Dual-Bay RAID Enclosure with 5Gbps USB-C Interface

Need more room for files, footage or backups? The UGREEN CM645 Dual-Bay RAID Enclosure lets you run two SATA drives from one compact unit, with a single USB-C connection to your computer. It takes both 2.5-inch and 3.5-inch drives, so you can reuse drives you already own instead of buying a ready-made external drive.

Choose RAID 0 for speed and combined capacity, RAID 1 for a mirrored copy of your data, or SPAN (JBOD) to join both drives into one large volume. If you simply want a reliable UGREEN hard drive enclosure for a desk, home office or small studio, the horizontal layout keeps both drives easy to reach.

The CM645 works with Windows, macOS and Linux, so you can use it with a laptop, desktop or media workstation. It suits photo libraries, video projects, document archives and everyday backups.

Key Features

• Dual-bay horizontal design: Holds two SATA drives side by side in one enclosure. You get double the storage from a single device and a single cable, and the layout is easy to place on a desk.

• Supports 2.5-inch and 3.5-inch SATA HDDs/SSDs: One enclosure fits both drive sizes. You can reuse old laptop drives, desktop hard disks or SSDs without buying a new unit.

• Multiple RAID modes (RAID 0 / RAID 1 / SPAN (JBOD) / PM): Pick the setup that fits your work. Choose speed and capacity, a mirrored copy, or one large combined volume.

• USB-C input: Connects to your computer with one modern port. That means less cable clutter and a simple setup.

• Up to 5Gbps theoretical transfer rate: Gives you fast access to large files such as photos, videos and project folders. Actual speed depends on your drives and computer.

• Windows, macOS and Linux support: You can move the enclosure between different computers and operating systems without changing your workflow.

Why Choose the UGREEN CM645 Dual-Bay RAID Enclosure
