With shared storage serving as an essential element in today's digital home, the D-Link ShareCenter DNS-320 2-bay network-attached storage (NAS) device enables you to easily share documents, files, and digital media with everyone on your home network. The expandable DNS-320 allows you to add up to two 2 TB SATA drives (for 4 TB of total storage*), offering plenty of space to store tons of digital photos, thousands of hours of digital music, or hundreds of DVD-quality movies. And adding a drive is a breeze with the D-Link tool-less design.

Whether streaming movies, sharing files, or storing video from a network camera, D-Link ShareCenter storage solutions are designed to let you work, play, and share from any room in the home or from a remote location over the Internet. A complementary piece to D-Link's digital home solutions, you can utilize ShareCenter products for a number of applications--whether it's connecting directly to the wireless router, storing video from mydlink-enabled IP cameras, or streaming video to your TV using the Boxee Box by D-Link.

Feature logos

Using the USB port in the DNS-320, you can share a single printer among all of the computers in a household over the network. Additionally, you can automatically download content from the web without powering on a PC with the integrated Peer-to-Peer Downloader or access files at top speeds without bottlenecking with the Gigabit Ethernet port.

The DNS-320 includes its own internal 800 MHz processor, a simplified interface, and software for finding and managing files. Its rugged, compact design makes for easy desktop placement. And it includes both AFP and Time Machine support for Mac users.

The DNS-325 model includes a faster internal processor plus support for specialized server apps. See a comparison of the two ShareCenter devices.

B.Y.O.D. (Bring Your Own Drives)

One of the best things about this ShareCenter device is that it comes without built-in hard drives. That means added flexibility and reduced strain on your wallet. Rather than being handed any old hard drive, you're free to hand pick the one that is the best fit for you. Choose the size. Choose the brand. Search for the best deal. Buy one. Buy two. The DNS-320 has two bays that can hold two SATA hard drives with up to a total of 4 TB of storage (2 TB per hard drive).

Back It Up

Keeping all of your important files on your computer without backing them up is like owning a house and not insuring it. It's important to back up your files so if the unexpected happens, you still have a backup in place. When used with two hard drives, this 2-bay ShareCenter device allows you to back up files in full or incremental backups and comes with four different hard drive modes so you can best configure it to your needs.

  • Standard mode creates two separately accessible hard drives
  • JBOD (Just a Bunch of Drives) combines both hard drives in linear fashion for maximum space efficiency
  • RAID 0 provides faster speeds by combining both drives in a striped configuration, which means data is distributed across both drives in the enclosure.
  • 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 like a single drive until the failed one is replaced. When a new drive is inserted, it's restored--returning full protection to both drives.

In addition to content back-up and RAID support for data protection, the DNS-320 also features remote access to files through a built-in web file server app and FTP server. With the included remote backup application, you can easily backup content to a second storage device at another location to protect against data loss in the event of a catastrophe.

The Power of Gigabit

This ShareCenter device comes with a 10/100/1000 Gigabit Ethernet port, giving you blazing fast speeds so you can back up and access your stuff without the wait.

D-Link Green

While this may look like your average storage enclosure, it's not. This is a D-Link Green storage enclosure, which means it's as good for your wallet as it is for the environment. This product:

D-Link Green
  • Features a fan that only comes on when hard drives need cooling
  • Allows hard drives to enter sleep mode when not in use to conserve electricity and prolong the life of the hard disk
  • Complies with the European Union's RoHS directive that restricts the use of certain hazardous materials
  • Uses recyclable packaging to help reduce waste that goes into the environment

How Do I Insert Drives Into My ShareCenter Device?

Insert drives

 

* Hard drive(s) not included. An internal SATA drive is required to store or share your files; drive must be formatted before use.

** 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 dependent on the drive capacity of the lowest-sized drive. May not work with older generation SATA drives.

Customer Reviews

Set up is easy if you are comfortable with your router setup menu.

UPDATE - August 2012: The D-Link support forum has some reports of a new beta release of Firmware (2.03b03) that some users report fixes the data corruption issue.

Good product overall, priced affordably and a great alternative to setting up a full server.

First and foremost, I tested this device by simulating a disk failure, and the answer is a resounding YES.

I received this NAS box from my sister, who asked me to 1) try out this DNS-320 out as a central file storage device, and 2) to set it up for her home, of course I agreed! She wants to centralize her files (photos, music, movies, etc.) so that the entire family can access them.

All the initial testing I did at my home using a D-Link DIR-655 Gigabit wireless N Router and gigabit ethernet on a WinXP Pro SP3 desktop and a Mac Pro (OSX SL). I have almost 1TB worth of pictures, and MP3 files, and over 2TB of home videos stored on my main desktop PC (WinXP Pro SP3), accessible to other computers on my home network as a shared folder. These files are backed up to a DNS-343 NAS box (4x2TB drives), and is backed up remotely to an identical DNS-343 box in my office (off-site). I also use the DNS-343 in my office as a backup of my workstation, and this DNS-343 is backed up remotely to my home DNS-343.

No problems with the setup (though I did perform a manual setup using the device IP). If you are not familiar with how to do a manual setup, I highly suggest to use the ShareCenter Software CD, which comes with the product. It goes through a step-by-step process of how to set up the unit.

The firmware was already the latest version, so no need to upgrade. I popped in two WD Caviar Black 1TB drives (these were my spare drives), connected the power and network cables and powered up, logged in using web GUI and configured the device for my network and use (DDNS, email settings, etc), formatted and setup drives for RAID1 (format did not hang at 94%), and it was up and running.

Pros:

This model is an improvement over the DNS-321, which tops out at 14-16MBps for write speeds. I populated it with a single firmware-updated Samsung F4EG drive; it's not on the compatible drive list but works fine. Copying files via Windows on a gigabit network, I get consistent write speeds in the 18-25MBps range (which is about 1.2GB per minute). Reading speeds vary from 30MBps to 52MBps. I also tried a 7200rpm Seagate drive with the same result, and also via the built-in FTP server. You might be able to squeeze out a little more performance with a different drive, but those speeds are likely limited by the NAS itself.

My primary use is to stream content to XBMC, and it performs that role perfectly. For other XBMC-on-Windows users, I'd recommend mapping via it the UNC address (like \\NAS\Volume_1) instead of mapping it via a drive letter in Windows. When the NAS goes to sleep Windows drops the connection and your apps might hiccup before it fully wakes, which is 10 seconds or less. My secondary usage is as a data backup, and it's fast enough so that doesn't take all day.

It's very green: According to the data sheet, it consumes 15.7w while in use and 8.2w while sleeping.

I played around with the uPnP / DLNA feature and that seems to work fine. You can plug in a flash drive in the front and press the button to create a backup, which is a neat feature.

Cons:

Like Windows, the performance seems to decrease over time so I'd advise periodic reboots. I left it on for two weeks and was only able to get write speeds of 10MBps. After a reboot, I was able to get 20MBps again. You can schedule it to turn off, but not to reboot.

Verified Purchase
Bottom line: D-Link tech support is beyond horrible - it took them ONE MONTH to respond to a support request, and it was a total non-response - basically, they told me that I shouldn't be using this product as a Network Storage Device, that it was designed more for [sic]"Backup's". So, they did not even address the fact that it corrupts data! Yes, you heard me correctly - it is not able to save data/files accurately!!! (With Firmware release 2.02, and now also the beta release of 2.03)

The unit ships with Firmware 2.0, and while there are some known (and D-Link admitted) bugs with this firmware, one thing I can say, it does not have the serious corruption issue I talk about in the first paragraph. I know this because (by accident) I bought 2 of these DNS-320 boxes so I have one with the 2.0 firmware that it ships with, and another that I upgraded firmware on. BEWARE: YOU CANNOT DOWNGRADE BACK TO 2.0 FIRMWARE IF YOU UPDATE THE FIRMWARE. D-Link says firmware 2.02 (or later) is needed to support 3tb drives and since that is what I was using, I updated the firmware. BIG MISTAKE. Now, I have a box that cannot be used.
AND SINCE D-LINK TOOK ONE MONTH TO GIVE ME NON-RESPONSE TO TECH SUPPORT REQUEST, I am beyond the Amazon return period.

Since the November 2011 release of Firmware 2.02, users have been reporting data integrity problems with the box - including files that get copied and then show up as "0 bytes". (See forums.dlink.com for DNS-320)

I say - do yourself a favor, and pass over D-Link products. The company cannot be trusted and is non-responsive to product defects/bugs.
IF you do purchase this product, DO NOT UPDATE THE FIRMWARE unless you want to experiment with a storage device that does not always store the data correctly.
