This SATA cable by Delock complies with the standard and provides a data transfer rate of up to 6 Gb/s, which is twice as fast as its forerunner. It enables an internal connection of SATA devices, e.g. HDD, controller card or flash memory. Furthermore the SATA 6 Gb/s interface is downward compatible to the elder versions, at which you can only achieve the respective transfer speed.
