UGREEN USB-C 3.0 to 2.5-Inch SATA Converter 50cm – CM321

The UGREEN CM321 transforms spare 2.5-inch SATA drives into portable USB storage for laptops and tablets. This 50cm converter cable bridges the gap between legacy storage hardware and modern USB-C devices. Students managing digital coursework and professionals juggling project files can quickly access archived data without installing drives internally.

Key Features & Benefits

• USB-C 3.0 connectivity: Delivers transfer speeds up to 5Gbps, moving a 10GB project folder in roughly 20 seconds instead of several minutes over USB 2.0
• Tool-free operation: Connects directly to SATA drives without screwdrivers or enclosures, ideal for quick data recovery or testing multiple drives in succession
• Universal SATA compatibility: Works with both SSD and HDD 2.5-inch drives, letting you repurpose old laptop storage or access backup drives from previous computers
• 50cm cable length: Provides desk-level flexibility when connecting drives to laptops without awkward positioning or tension on ports
• Plug-and-play design: Requires no driver installation on Windows, macOS, or Linux systems, eliminating setup hassles during time-sensitive file transfers

Use Cases & Applications

For Students: Convert old laptop drives into external storage for thesis research, keeping years of academic papers accessible without cloud subscription costs. The UGREEN CM321 turns a retired laptop SSD into a portable backup drive for semester projects.

For Business Professionals: IT administrators use SATA converters for rapid drive diagnostics and data migration during hardware refreshes. The 50cm length allows technicians to work comfortably at their desks while imaging drives or extracting files from decommissioned workstations.

Data Recovery Scenarios: When a laptop fails but the drive remains intact, this converter provides immediate access to critical files without sending devices for professional recovery. Simply extract the 2.5-inch drive and connect it to a working computer via USB-C.

Cross-Platform File Transfer: Move large media libraries between a Windows desktop with internal SATA storage and a MacBook with only USB-C ports. The plug-and-play design eliminates compatibility concerns across operating systems.

The UGREEN CM321 proves particularly valuable for anyone maintaining multiple storage devices or transitioning between computer generations. Its straightforward design prioritizes function over unnecessary features, making it a practical tool for both occasional drive access and regular storage management tasks.
