Description: Now you can quickly and easily add storage space onto your network with the Linksys Network Storage System. This stand-alone network appliance features two available SATA hard drive bays so you can attach as much storage as you need now, and add more later as your storage needs grow. For even more expandability, there are two USB ports that let you connect readily available USB 2.0 hard drives for even more storage space — or plug in a USB flash disk for a convenient way of accessing your portable data files.
