The 2big Network can act as a file-sharing server, a backup server or an FTP server. Easily share important files and make them accessible from anywhere via FTP or any web browser. With this affordable 2-disk RAID solution with Ethernet interface, get maximum storage capacity in BIG mode or maximum security in SAFE mode (RAID 1). If one drive fails in RAID 1, data remains accessible and can even be automatically rebuilt onto a hot-swappable spare drive. With the 2 USB ports, easily transfer files from a USB key or USB hard drive with the 1-Click Data-Sharing Button or expand available network capacity. The new heat sink metal design naturally draws heat away from the hard disk's internal components to help keep it cool and improve reliability. The user-friendly LaCie Ethernet Agent enables direct access to shares, drive mapping, and easy administrator configuration.
