For the price, the cable is good. This is lt. Imprint a SATA 6Gb / s cable (S-ATA III), which is obviously crimped together by the meter (or SATA Crimping Crimping eSATA are printed on the connectors). The cable itself is obviously not a double-shielded eSATA cable, but "only" a S-ATA cable for use in a PC, just with the difference that an e-SATA connector attached to one side is. Despite the length of one meter, I could not detect any interference received, including SMART showed no transmission errors, that's good. The E-SATA connector itself is handy and can be compared to the S-ATA connectors do not just pull out, as it should be, an e-SATA hard drive could be moved so without that the connection is cut. The S-ATA connector snaps cleanly as we know it, but has no separate lock, which is not even required, as this cable is obviously meant to fertilize the motherboard the SATA port with this cable. For me this e-SATA extended to S-ATA cable my little "all-purpose" by a fifth internal disk.
