UGREEN 2.5″ Hard Drive Enclosure USB 3.0 to SATA III Adapter | 30848
The UGREEN US221 (#30848) is a 2.5-inch enclosure that turns a 2.5-inch SATA hard drive or SSD into a portable USB 3.0 drive. It transfers data at up to 5Gbps, supports UASP, and takes drives with a capacity of up to 6TB.
USB 3.0 at up to 5Gbps: The enclosure connects over USB 3.0 with transfer speeds of up to 5Gbps, so copying large folders, photos and videos takes far less time than over USB 2.0. It also works on USB 2.0 ports, at USB 2.0 speed.

UASP for faster transfers: UASP is a transfer protocol that speeds up reading and writing compared with standard USB 3.0 mode. You get this boost when the computer also supports UASP; otherwise the enclosure works in normal USB 3.0 mode.

Tool-free installation: Slide the cover open, push the drive onto the SATA connector and slide the cover back. No screwdriver is needed, and a shock-absorbing pad inside keeps the drive firmly in place.

Fits 7 mm and 9.5 mm drives: The enclosure takes standard 2.5-inch SATA hard drives and SSDs that are 7 mm or 9.5 mm thick, which covers most laptop drives. This makes it a simple way to reuse a drive from an old laptop as external storage.

Detachable 30 cm cable: The drive connects through a short USB-A to Micro USB cable that plugs into the enclosure. Because the cable is detachable, it can be replaced if it is ever damaged.

Who it's for / Works with
Works with Windows, macOS and Linux computers. UGREEN also lists game consoles such as PS5, PS4 and Xbox, smart TVs and routers as compatible devices.
Good to know
- The enclosure is for SATA drives only; IDE drives are not supported.
- UASP speeds need a computer and drive that also support UASP.
- The hard drive or SSD is not included.
- Always use "Safely Remove Hardware" on the computer before you unplug the drive.
