The DNS-313 Single Bay Network Storage Enclosure, when used with internal SATA drives, enables you to share documents, files, and digital media such as music, photos, and video with everyone else on the home or office network. Remotely accessing files through the Internet is also possible with the built-in FTP server. Whether allowing access locally or over the Internet, keep data safe by only giving rights to specific users or groups. When configuring the DNS-313, you can create users and groups and assign them to folders with either read or read/write permissions. This is ideal for an office environment with employee-specific sensitive data or for home where children can be ensured to have access only to age-appropriate materials.Back up music, photo, and video collections to the DNS-313 for safekeeping. Then, enjoy the benefits of the built-in iTune and UPnP AV media server to stream music, video and other digital content to compatible media players. This feature is highly convenient as it allows users to turn off a computer that would normally be needed for the same function.The DNS-313 can be flexibly used as a Network Attached Storage (NAS) or a Direct-Attached Storage (DAS). As a NAS, it connects to an office or home network through a high-speed Gigabit port for shared disk access. As a DAS, it connects through a USB 2.0 port of a server or your personal laptop computer for use as a portable external USB hard drive. The DNS-313 features simple hard drive installation and is very handy when you need to store large files and carry them around to work or back home, or when you travel.
