USB 3.0 to SATA adapter cable lets you connect a 2.5" SATA hard drive or solid state drive to your computer through an available USB port -- the easiest way to upgrade the hard drive in your laptop by adding an external SSD via USB 3.0. APPLICATIONS: • Use with an SSD drive to externally upgrade your laptop hard drive via USB 3.0. • Create an external storage solution on the go, for desktops, laptops or Ultrabook computers. • Access any 2.5" hard drive or solid state drive from any USB enabled computer, for data migration or drive cloning. • Take advantage of USB 3.0-enabled laptops or desktops with UASP for faster transfer speeds. • Back up important data to an external storage device. • Retrieve data from an old SATA drive. NOTE: • Not compatible for 3.5” hard drive. • Not compatible with ATA(IDE), MSATA, and M.2 interfaces. • The new hard disk must be partitioned before use. • Affected by the maximum hard disk read and write speed, the SSD read and write speed is between 400-600MB/S, the HDD read and write speed is generally under 300MB/S.
