D-LINK ShareCenter DNS-340L 4 x Total Bays NAS Server - External

The DNS-340L ShareCenter™ + 4-Bay Cloud Network Storage Enclosure is an easy-to-use solution for accessing, sharing, and backing up your important data by creating your own personal cloud. Multiple RAID options allow you to keep all of your data safely stored and protected at home, and still have it at your fingertips with this sleek, high-octane NAS device.

Powerful Performance and Flexibility
A plethora of different hard drive modes are available (Standard, JBOD, RAID 0, 1, 5, 10, 1+0), which allow users to choose the configuration best suited to their needs. Standard mode creates two separately accessible hard drives. JBOD combines both drives to create a single, easy to use volume. RAID 0 combines both drives in a "striped" configuration, which provides maximum performance. RAID 1 creates a copy of your data on both drives, providing maximum protection. RAID 5 combines space from three of your hard drives and uses the fourth drive as a parity drive. RAID 10 protects data against loss of non-adjacent disks and uses the disk striping technique to speed up operation when retrieving data from disk storage. The DNS-340L is hot swap enabled meaning you can easily replace a failed drive and your data will automatically be copied to the new drive, allowing the ShareCenter to return to its full level of protection and ensuring your files remain safe.
