The expandable DNS-325 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.

Using the USB port in the DNS-325, 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-325 includes its own internal 1.2 GHz processor, a simplified interface, and software for finding and managing files. Its rugged, compact design makes for easy desktop placement. It also includes applications, such as a photo gallery, an audio streamer and a Blog application that allows you to host your own blogs directly from the device. It can also support additional add-on applications as they are developed. And it offers 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-325 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-325 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.

My wife and I have started digitizing a lot of audio and VHS tapes, and scanning gazillions of photos for our genealogy. I needed a LOT of storage that would be safe and secure. More importantly, I didn't want to fill our personal PC hard drives up with difficult-to-replace files. Hard drive failures happen all the time. I had never owned or used any kind of network storage before, so I did a lot of online research and settled on the DNS-325. The reasons were primarily the ease with which I could plop in the hard drives, configure them to RAID-1 (mirrored backup) and conveniently give everyone in my house access over our network. Previous versions of this unit (ex: DNS-320) seemed to get pretty consistently good reviews. I opted for the DNS-325 over other versions, primarily because of the increased performance and faster processor. I have also owned a number of D-Link products over the years, and have always been happy with their quality and performance. So far, the DNS-325 hasn't disappointed.

Installation was a piece of cake. I bought two 3TB hard drives, installed them in the ShareCenter in a matter of seconds, plugged in the ethernet cable and power cable, and from a pc connected to the LAN, ran the installation program on the supplied DVD. After deciding on RAID-1 configuration, it formatted the drives and I went through the other menu options configuring it the way I wanted. I physically located the unit next to my cable modem and router...in our basement.

Then came a surprise. From my connected PC, I discovered that the 3TB hard drives only had 785MB of available storage! I went to D-Link forums and discovered that the firmware version it came with (1.01) did NOT support 3TB hard drives, but the latest version that you can download (1.

I love my DNS-325 so far. At the moment, I have a single WD 2TB "Green" hdd installed. I like the small footprint, the ease of installation, the web browser interface, and the power savings. It boots up fast too. And it's super quiet.

I previously had a homemade file server (basically an old 700MHz Compaq PC with two 500GB hdds installed, running Ubuntu Server). This Dlink just sips the power. I measured both the old server vs the Dlink DNS-325 using a Kill-a-watt. Here are my findings:

My old server was using ~ 72.5 W. The DNS-325 used 8 W (3.5 while asleep).

My old server used 13.96 kWh over 209 hrs. The DNS-325 used 0.14 kWh over 24.39 hrs.

My old server cost roughly $4.26 per month to operate. The DNS-325 should cost at most 37 cents. It will be less than half that if I allow it to sleep.

This Dlink uses less than 1/10 the power that my old file server used. It will pay for itself in less than three years.

Okay, I've read reviews on other sites and there were a lot of people complaining about this box and how hard it was to setup, etc. Not true! I added this box to my network to help with my migration from a Windows desktop to a Macbook. Basically wanted a storage server that could host my home videos, music, pictures, etc since my Macbook has limited drive space. This was the answer for me! I added two Seagate 1TB drives, went through the easy setup wizard and I was off and running. Setting up users, groups, shares, etc. isn't difficult if you have any IT experience. Yes, certain administrative things are buried in the web interface, but add these functions to your favorites and you'll be golden. I connect this box to my gig network via Ethernet, so transfer speeds are not bad. Skip the USB and add this to your network via Ethernet. I backup my data from this NAS to my old DNS-320 with no real performance issues. I also stream video from this box to my AppleTV 2nd Gen with no issues. I no longer need my large Windows desktop, so out the door it goes. If you're looking for a decent NAS that won't break the bank, then this is the answer for you.

With multiple computers in the house I wanted a central location for backups and selected this unit. The installation of the WD hard drives (2TB Green times 2) was easy as well as attaching it to my network. The supplied software has work fined for backing up our computers. Updating the firmware and software from the D-Link site was simple.

Setting up passwords and access for our family users was fairly easy.

I activated the media software that came with the unit. Transferred a DVD to the unit, entered the password in our WiFi enabled DVD player and watched the movie on our flat screen TV. The image quality and the sound are great.

The only issue I'm having is getting the printer port to work consistently. I'll get it to print and something will go wrong. I'm about to give up on it and from what I read on the web I'm not the only one with issues. The problem is a bother, but since I didn't buy the unit for the print server it isn't a deal killer.

The unit has been running cool. I have yet to get the unit's fan to turn on. I tried by streaming a movie and backing up two computers simultaneously. Didn't get warm enough to turn on the fan.

I set the unit to go to sleep when not being used. Haven't had any issues with waking it up.
