1. Interface and Speed:
The UGREEN CM321 uses the USB-C 3.1 Gen 2 interface, which offers a maximum theoretical data transfer rate of up to 10 Gbps. This high-speed transfer capability allows efficient data migration between the SATA drive and your computer, ideal for quick backups, data recovery, or disk cloning tasks.
2. Compatibility and Drive Support:
This adapter is specifically designed for 2.5-inch SATA drives, including both HDDs and SSDs. It supports SATA III, which is backward compatible with SATA II and SATA I drives. Due to the USB-C connector, it can be connected directly to modern laptops, desktops, or devices that feature USB-C ports.
3. Plug and Play Design:
One of the major benefits of this adapter is that it requires no additional driver installation, ensuring hassle-free operation across major operating systems like Windows 7/8/10/11, Mac OS X, Linux, and Chrome OS. Simply connect the SATA drive to the adapter, plug into a USB-C port, and it’s ready to use.
4. Power Supply:
The adapter draws power directly from the USB-C port, meaning there is no need for an external power adapter. This makes it very portable and convenient for on-the-go use. However, since it is designed for 2.5" drives (which are low power), it is not suitable for 3.5" desktop hard drives that require additional power.
5. Durable Build and Heat Dissipation:
The cable and connectors are constructed with sturdy materials, including an aluminum alloy housing around the connectors. This not only provides durability but also helps in dissipating heat generated during data transfers, protecting both the adapter and the connected drive.
6. Backward Compatibility:
Although optimized for USB 3.1 Gen 2 speeds, this adapter can still be used with older USB 3.0 and USB 2.0 ports, albeit at reduced transfer speeds. This ensures versatility and compatibility with a wide range of devices.
7. Use Cases:
Data Migration: Ideal for transferring data from old laptop drives to new machines.
Backup and Recovery: Allows quick access to data on SATA drives for backup or recovery.
Drive Cloning: Supports cloning software operations for upgrading or replacing drives.
Portable Storage: Turns internal SATA drives into external portable drives.
