Got (2 pieces) today and tried glech the cable. These fit very well on my Gigabyte eSATA ports. The plug-in connection to the hard drive are just as precisely. The Wichstigste now - the function: Impeccable! Plates are immediately recognized and integrated by the system. The transmission speed is the like of the internal SATA ports. Since everything is working fine, and also seem to be some reasonably hochwerig the cable, I forgive the full 5 stars.
