The UGREEN CM321 is a practical adapter designed to connect 2.5-inch SATA HDD or SSD drives to your computer via a USB-A 3.0 port. By supporting the UASP protocol, it allows for faster data transfers up to 5Gbps, making it efficient for those who need to move large files quickly between an external drive and their system. This black adapter is built with robust materials and includes a flexible 50cm cable that provides enough reach to position your drive comfortably on your desk. It handles capacities up to 5TB and integrates S.M.A.R.T and TRIM support to help maintain the health and performance of your storage over time. To keep your hardware safe, it features built-in protections against overheating, overvoltage, and power fluctuations. Since it is a plug-and-play device, you can start using it immediately without installing any drivers. An LED indicator lets you know the current status of the connection, while an auto-sleep function helps manage power consumption when the drive is idle, which is particularly useful for users who frequently swap drives for backups or data recovery.
