Is there any way I can connect 14 different external USB hard disks together to a Windows 7 64 bit desktop PC? My system has only two USB ports. I want to mount all these external disks together as different drives in the system.

Right now, I am able to connect one External hard disk using the PC USB port.

I have read that there are USB Hubs available which provides 10 USB ports. Has anybody tried USB hubs to connect more external hard disks (more than 6)? Is there any known issues like performance difference from connecting them like this?
