iSCSI Target Capability

Powerful Performance and Flexibility

A plethora of different hard drive modes are available which allows users to choose the configuration best suited to their needs. Standard mode creates four separately accessible hard drives. JBOD combines the four drives to create a single, easy to use volume. RAID 0 combines the four drives in a "striped" configuration, which provides maximum performance. RAID 1 creates a copy of your data on two or more 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 stripping 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.

Share Your Files From Anywhere

The ShareCenter + 4-Bay Cloud Network Storage Enclosure includes a web-enabled file server which allows you to download your documents, photos and other multimedia files from wherever you are. Once configured, simply log into your ShareCenter using the friendly web user interface to view a list of available files.

You can also connect to the DNS-340L with the mydlink Access - NAS app to access and play music, watch videos and view photos directly on your mobile device. With the mydlink portal, you'll never have to bother with configuring complicated network settings to enable remote access to your content.
