Posted June 5, 201212 yr FPCH Admin my laptop OS is Wind 7 and has 3 usb ports. how do i know if they are compatible with usb 3.0 transfer technology (eg an external hard drive that is capable of transferring data at 3.0 speed). the device manager in control panels does not seem to reveal this information. Alternatively, if the external hard drive can transfer data at 3.0 speed, does my laptop have to be compatible with this? View the thread Off Topic Forum - Unlike the Rest
