A USB hub is a device that expands a single Universal Serial Bus (USB) port into several so that there are more ports available to connect devices to a host system, similar to a power strip. All devices connected through a USB hub share the bandwidth available to that hub.With a multi USB port HUB, you'd be able to connect all your USB hard drives at once and simultaneously transfer the photos to other. Some USB port hubs even come with SD card slots, so you could transfer the photos directly from your port hub. You wouldn't have to transfer them to your computer first.
