I have core i5 with 4 gb ram and 500 gb hard 2nd generation. My work is copying data from laptop to mobiles , sd cards and in usbs . My question is how can i do copy fast ?
It definitely would not hurt to have some more RAM, but generally there is not many ways to speed up transfer speeds for USB.
If you are not already using usb 3.0 upgrade to usb 3.0 devices and hubs for transferring data.
