The U30AS25 USB 3.0 to SATA adapter cable allows you to connect a 2.5" SATA hard drive or solid state drive to your computer through an available USB port providing the easiest way to upgrade the hard drive in your laptop by adding an external SSD via USB 3.0. U3 AS25 supports UASP, allowing for transfer speeds up to 7 % faster than conventional USB 3.0, which enables you to utilise the full potential of your SATA III SSD/HDD when paired with a UASP-enabled host controller.
