1) My usb drive MyPassport not working on my Synology NAS (rattling, due to a lack of supply). I plug one of the 2 two doses of this cable (Y): The drive is powered and works perfectly! The cable diameter is good and short, so no loss of energy. 2) Concerning the command: shipment from england frightened me about the time (announced between 30 September and 9 October). Excluding the order was shipped the same day and received on 30 September. 3) Regarding the price, it is unbeatable. The quality is very good. Thank you
