Introduction: External Storage, Made Instantly

Do you have old laptop drives, SSDs from a recent upgrade, or a collection of SATA hard drives you still need data from? Whether you’re a tech enthusiast, data recovery expert, or everyday user, quick access to internal 2.5″ drives should be simple and fast.

The UGREEN CM321 USB-C to SATA Converter gives you that convenience. With a USB-C 3.0 interface, 5Gbps transfer speed, and support for 2.5-inch SSDs and HDDs, this adapter transforms any internal drive into an instant external solution.

This lightweight, portable, plug-and-play tool is available at Phonex Technologies Kenya, ideal for data transfers, backups, system cloning, or just browsing through archived storage.

• Photographers accessing files from SATA SSDs

5Gbps High-Speed Data Transfer – No Bottlenecks

Using the USB 3.0 standard via a USB-C connector, the CM321 supports transfer rates of up to 5Gbps—roughly 10 times faster than USB 2.0. In practice, that means:

• Moving a 10GB video in seconds

• Rapid OS installations from an external SSD

• Seamless booting into external drives

• High-speed cloning and backups

• Time-efficient file access for large projects

And with UASP (USB Attached SCSI Protocol) enabled systems, it offers even better performance, reducing latency and improving command queuing.

Tool-Free and Driver-Free Convenience

Forget about enclosures, mounting brackets, or software installations. The CM321 is:

• Plug-and-play

• Tool-free

• No drivers required

Just plug the USB-C end into your computer and connect the SATA port to your SSD or HDD. That’s it.

This makes it ideal for quick troubleshooting, temporary access, or on-the-go tech support. It’s also perfect for laptops without traditional SATA bays or users working across multiple machines.

2.5-Inch SATA SSD and HDD Support

The CM321 is specifically engineered for 2.5-inch SATA drives, the most common storage format in:

• Laptops

• PS4 and Xbox consoles

• External storage modules

• Cloning kits

• Surveillance systems

It supports SATA I (1.5Gbps), SATA II (3.0Gbps), and SATA III (6.0Gbps) drives, with backward compatibility across all versions.

Capacity? Up to 6TB, more than enough for most home and office use.

---

USB-C Interface – Forward-Looking and Reversible

This adapter features a USB-C 3.0 interface, delivering:

• Reversible plug orientation

• Faster speeds over traditional USB-A

• Compatibility with modern devices (laptops, tablets, MacBooks, etc.)

• Reduced wear and tear from frequent connections

If your laptop has USB-C ports, this adapter is the logical choice for faster, more convenient connectivity.

---

50cm Cable – The Perfect Length

Some converters are too short, putting unnecessary strain on your USB port and making workspace organization difficult. At 50cm, the CM321 offers:

• Enough slack for clean desk setups

• Reduced cable tension

• Flexibility for vertical or horizontal drive placement

• Room to keep your drive safe from falls or vibrations

It’s compact, but never restrictive.

---

Broad Operating System Compatibility

Whether you’re running Windows, macOS, or Linux, the CM321 has you covered. Supported systems include:

• Windows 11/10/8/7/XP

• macOS Catalina, Big Sur, Monterey, Ventura

• Linux distributions like Ubuntu, Fedora, Mint

• Chromebooks with USB-C ports

No additional software needed. It’s true plug-and-play across platforms.
