I bought an external 500GB hard drive with cable that has one end normal micro USB and the other end is split into two regular USB connectors. I have Mac Book Air, which has only one USB port on each side. Is it sufficient to connect the hard drive with only one USB (so I can use regular cable, not the one enclosed)? The hard drive works while connected with only one USB. Do I suppose correctly that it only effects the speed of the data transmission?
Thank you for answers.
