UGREEN 70499 USB-C 3.1 Gen 2 2.5-Inch SATA HDD/SSD Enclosure – Silver (Open Sealed)

Description

The UGREEN 70499 is a portable external drive enclosure designed to convert a compatible 2.5-inch SATA HDD or SSD into an external USB-C storage drive.

It supports SATA I, SATA II and SATA III drives with a thickness of 7mm or 9.5mm, making it suitable for many laptop HDDs and 2.5-inch SATA SSDs. The internal SATA III interface supports a theoretical data path of up to 6Gbps, while UASP support helps provide efficient storage performance with compatible systems.

The aluminum-alloy housing helps protect the installed drive and dissipate heat during operation. Installation is tool-free, and the enclosure is powered directly through USB, so no separate power adapter is required.
