The D-Link® 4-Bay Network Enclosure (DNS-343) is the perfect way to store, share, and safeguard your documents, music, videos, and photos. With the D-Link tool-less installation, you can easily insert up to 4 SATA drives1 without any tools or attaching any cables. Plus, the DNS-343 is a scalable solution, allowing you to start off with one SATA hard disk drive (HDD) and add up to 3 more as you grow.

PROTECTION, PERFORMANCE AND FLEXIBILITY
By supporting RAID 0, 1, 5, and JBOD, the DNS-343 gives you a variety of data protection options to help avoid data loss due to hard drive failure. RAID 0 combines all drives in a ‘striped’ configuration, splitting data evenly across the hard drives to provide the highest performance. RAID 1 causes two drives to mirror each other, providing maximum protection. If there are four drives present, you can set up two separate RAID 1 partitions. If one drive fails, the unaffected drive in the partition will continue to operate normally. Once you replace the failed drive, RAID 1 mirroring will resume and both drives will mirror each other again. Advanced RAID 5 offers the highest performance with the most reliable data recovery in the case of a drive failure. RAID 5 technology uses a clever algorithm to distribute your data over 4 SATA hard disk drives and, in the case of a hard drive failure, the DNS-343 will continue to function with your data intact.

SIMPLIFIED MANAGEMENT
With the included backup software, you can create schedules and rules including real-time full or incremental backups and storage quotas for specific users and groups. Using backup software, you can automatically back up your data onto the DNS-343, creating a failsafe protection solution from accidental data loss on your PC. The 4-Bay Network Storage Enclosure features an OLED to display important information including IP address, hard drive statistics, temperature, RAID status, and server status (FTP and UPnP™).

USB PORT FUNCTIONALITY
The USB port can act as a print server port, allowing a USB printer to be added to your network without the need for a dedicated computer. The USB port can also support a Universal Power Supply (UPS) monitor that supports ‘smart’ signaling over a USB connection. If a power outage were to occur, the compatible UPS monitor would allow the UPS unit to safely shut down the DNS-343. When power is restored, the UPS monitor would then automatically power up the DNS-343.

For flexible usage, the DNS-343 includes features such as a built-in FTP server2 to access files over the Internet and a UPnP™ Media server to stream digital content to compatible media players. With RAID 5 technology, an OLED that displays vital storage information, a management program that allows you to easily set rules and schedules, and a variety of built-in servers, the 4-Bay Network Storage Enclosure (DNS-343) is a secure expandable and reliable storage solution for the home and business.
