Connects 2.5 or 3.5 inch SATA drives via USB 3.0 at up to 5 Gbps with included 12V 2A power adapter
This adapter cable turns a standard 2.5 or 3.5 inch SATA HDD or SSD into an external USB 3.0 drive. It connects via a 22-pin SATA interface and includes a 12V 2A power adapter for reliable operation with larger desktop drives. The device is plug-and-play and supports hot-swapping for quick drive changes.
The adapter delivers up to 5 Gbps over USB 3.0 and supports UASP technology. UASP reduces processor overhead by 80 percent and can move data 70 percent faster than traditional USB 3.0 bulk endpoints when the host controller also supports UASP. This helps maintain throughput during long copy or backup sessions.
The unit has no fan and draws power from the included 12V 2A adapter, so it adds no audible noise beyond the connected drive itself. The external supply ensures stable voltage for 3.5 inch drives that cannot run on bus power alone. Power consumption scales with the attached drive rather than the adapter.

The included 12V 2A power adapter provides the extra current a 3.5 inch SATA drive needs for continuous operation; the adapter connects to the cable's DC-Jack port.
You need a USB 3.0, 2.0 or 1.1 port on the host and a 2.5 inch or 3.5 inch SATA HDD or SSD with a 22-pin connector; the 12V 2A adapter is required for 3.5 inch drives.
UASP requires a UASP-enabled host controller; the adapter falls back to standard USB 2.0 or 1.1 speeds and remains compatible with SATA 1.5 Gbps drives.
