This SATA to USB cable is an external drive adapter that gives you quick and easy access to a SATA drive through the USB-A port on a laptop. This SATA solid-state (SSD) or hard drive (HDD) adapter lets you upgrade to an external 2.5" SATA SSD or HDD. The cable lets you: add drive space, perform backups, create disk images, implement data recovery, and transfer content between the drive and the laptop. The cable supports USB 3.0 data transfer speeds of 5Gbps. But, you can experience transfer speeds up to 70% faster than conventional USB 3.0, when connected to a computer that also supports UASP. With UASP you can utilize the full potential of a SATA III SSD or HDD. UASP is supported in Windows 8, Mac OSX (10.8 or above), and Linux. In testing, UASP performs with a 70% faster read speed and 40% faster write speed over traditional USB 3.0 at peak performance. At the same peak in testing, UASP also shows an 80% reduction in required processor resources. The SATA to USB cable is a portable solution that tucks away nicely in a laptop bag -- no external power is required. The cable lets you easily swap between drives with no need to install the drive inside an enclosure. It s plug-and-play and doesn t require drivers.
