Guest NewsBot Posted June 5, 2012 Share Posted June 5, 2012 <span>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?</span> View the thread Quote Link to comment Share on other sites More sharing options...
