Neatly packed in plastic Sackerl, dustproof thus.
Have a special test done and 2 "this" cable hung together, so that the line was then 2 meters long:
*) My PC: Motherboard ASUS P5Q, Intel Core 2 Duo E8400 (= 3 GHz), 4 GB RAM; Windows 7 64-bit Home Premium; Source HDD: Seagate Barracuda 7200.11 1000GB, 32MB (ST31000340AS)
*) In PC: Transcend USB 3.0 interface card / adapter PCIe (2 ports)
*) External Hard Drive: 2.5 inch Western Digital Scorpio Blue 1000GB, 8MB WD10JPVT in RaidSonic Icy Box IB-housing-250StU3 + BH
Result: no speed loss! Unchanged 74 MB per second (testhalber copied in a train 5 films) is written to the external plate.
See if required, uploaded my pictures.
Can only recommend the cable.
