Bought but never used, unboxed but with all accessories. NO HARD DRIVES (comes as originally supplied). I have another one at home and it's awesome. Fast, and reliable and goes to sleep (completely silent) if you're not using it, so very energy friendly. SAFELY SHARE DIGITAL FILES LOCALLY AND OVER THE INTERNET The D-Link DNS-323 2-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 on the home or office network. Remotely accessing files through the Internet is also possible with the built-in FTP server2. Whether you are allowing access locally or over the Internet, keep data safe by only giving rights to specific users or groups. When configuring the DNS-323, you can create users and groups and assign them to folders with either read or read/write permissions. Watch episode on how to backup and share your files, music, photos, and video. STREAM DIGITAL MEDIA CONTENT TO UPnP™ AV COMPATIBLE MEDIA PLAYERS Back up your music, photo, and video collections to the DNS-323 for safekeeping. Then, enjoy the benefits of the built-in UPnP AV media server as you stream digital content to compatible media players (such as those found in D-Link's MediaLounge™ product line). This feature is highly convenient as it allows you to turn off a computer that would normally be needed for the same function. Mirroring hard drives with Raid 1 Technology PROTECTION, PERFORMANCE, AND FLEXIBILITY The availability of four different hard drive modes (Standard, JBOD, RAID 0, RAID1) allows you to choose the configuration best suited to your needs. Standard mode creates two separately accessible hard drives. JBOD combines both drives in linear fashion for maximum space efficiency. RAID 0 combines both drives in a 'striped' configuration, which provides the highest performance, enabling speeds up to 23MBps-Read and 15MBps-Write (MBps: Megabytes per second) when using a Gigabit Ethernet connection3. RAID 1 causes the drives to mirror each other, providing maximum protection. If one drive fails while configured as RAID 1, the unaffected drive continues to function as a single drive until the failed drive is replaced. The new drive will then be remirrored, allowing the DNS-323 to return to its full protection. WHAT THIS PRODUCT DOES The D-Link DNS-323 2-Bay Network Storage Enclosure, when used with internal SATA drives1, enables you to share your documents, music, photos, and videos across the network and on the Internet so family members, friends, or employees can access them. This enclosure also allows you to create a central network point for backing up valuable files and the built-in RAID 1 mirroring technology protects these files from drive failure. You can also use this device to stream music, photos, and videos to UPnP™ AV compatible network media players4. Save time using D-Link’s Easy Search Utility ROBUST SOFTWARE INCLUDED The included CD contains D-Link's Easy Search Utility. This utility allows you to easily locate the DNS-323 anywhere on the network. Once located, use the utility to map the hard drive(s) so they will appear in My Computer on your PC. Backup software is also included on the CD. This will allow the back up of valuable files from a computer to the DNS-323 manually, by a schedule, or in real-time. Real-time backups are a great way to safeguard against unfortunate accidents that may result in the loss of precious files. 1. Hard Drive(s) not included. An internal SATA drive is required to store or share files. RAID 1 mirroring requires the use of two (2) internal SATA drives. To avoid data incompatibility in RAID 1 operation, use SATA drives from the same manufacturer. Formatted drive capacity for RAID 1 operation is dependant on the drive capacity of the lowest-sized drive. May not work with older generation SATA drives. 2. Note that use of an FTP Server to access files over the Internet does not provide for secure or encrypted transmissions. It is recommended that the end-user utilize a Virtual Private Network (VPN) to establish a secure FTP session. 3. Speed results will vary depending on the benchmark utility, hard drive configuration, and the network environment used for testing. 4. D-Link cannot guarantee full compatibility or proper playback with all codecs. Playback capability depends on the codec support of the UPnP™ AV media player.
