Any other way? Does connecting a laptop to PC via two way USB cable serve the purpose?
With the piece of equipment that you may have , the answer would be no.Don't even try that.You may damage some components on the PC.
The fastest method to transfer data would be to connect the two devices through Gigabit Ethernet Lan Cable. { considering that both of your devices support GBE ports.}
The average data transfer rates should theoratically be 125MB/Sec , but depending on various factors you'll get around 30-40MB/Sec , which is really good.
This is the best method unless you bring in the Solid State Drive for transferring Data or a USB3.0 Drive.
THE GBE LAn method is easiest and feasible because almost all new generation devices support th'm.
