As against the product does not work correctly with a USB 3.0 drive
As the comments already indicated, including shorter lengths, disk disconnects regularly or is not recognized.
Moreover Windows 7 frequently indicates that the disk must be reformatted when he is new.
When the disc is recognized via this cable, transfer rates are close to those of a floppy disk !!!
FYI, the drive has been tested with the original cable (50 cm) and there is no problem, with an average transfer rate of 83.4 Mb / s.
