Product Description
Capacity: Diskless
From the Manufacturer
The D-Link ShareCenter 2-Bay Network Storage Enclosure (DNS-321) connects to your network instead of to a computer so everyone on your network can back up content to one central location. Plus, it lets you share your stored content across your network and over the Internet so family members, friends and employees can access it no matter where they are.
This version of the DNS-321 does not come with a hard disk drive, enabling you to add your own hard drives (see specifications below).

With Sharecenter You Can
 |  |  |  |
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. The ShareCenter 2-Bay Network Storage Enclosure can house up to two 3.5-inch SATA hard drives of any capacity1, giving you plenty of space to store your music, photos, videos, documents and other important stuff. When used with two hard drives, the 2-Bay ShareCenter 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 12 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. Two is better than one.
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 sky is the limit.
Bundled Software
With bundled software, you never have to worry about your hard drive crashing. Not only does it let you restore individual files and documents in case they get lost, it lets you take snapshots of your entire hard drive so you can restore your computer to the way it was when the snapshot was taken.
Sharing is Caring
Because this enclosure connects to your network instead of directly to a computer, it allows you to share all of your saved content over your network. Music, photos, videos ... think of the possibilities! And no need to worry about the safety of your stuff. You can give rights to specific users or groups and assign them to folders with either read or read/write permissions. This is perfect for an office environment with employee-specific data or for the home where you can ensure your children will only have access to age appropriate material.
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:
- 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
The D-Link Easy Utility
The D-Link Easy Utility allows you to easily locate the 2-Bay ShareCenter from anywhere on the network. Once it is located, you can use the utility to map the hard drive so it will appear in My Computer on your PC.
Easy Peasy
Not quite the handyman? That's OK. You can insert hard drives without using any tools or attaching any cables.
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.
Be Cool
There's no overheating in this enclosure's future. It comes with a quiet built-in fan to keep things nice and cool.

ShareCenter Connects to Your Home Network
One of the biggest misconceptions about ShareCenter devices is that they are simply external hard drives. Sure, they protect your stuff in case your hard drive crashes. And yeah, they allow you to back up your digital content so you can save space on your computer. But unlike external hard drives, ShareCenter devices connect to your home network instead of to a single computer, which means they can go far above and beyond the limits of an average external hard drive.
Share Files Over Your Home Network
Because ShareCenter devices connect to your home network, they are able to back up and store content from all of the computers on your network instead of just one. That means while you're backing up work documents from your laptop, the rest of the family can back up the digital photos and music from their computers. Plus, because all of that digital content is being stored in one central location, it's easy for everyone on the network to share it between computers. And no need to worry, ShareCenter makes it easy to control who has access to what, so privacy isn't an issue.
Access Your Content from Anywhere
ShareCenter devices feature built-in FTP servers, which enable you to access your saved content remotely over the Internet. Once you set up an FTP server, you can access all of your music, videos, photos and documents from virtually anywhere. That's right. Thanks to ShareCenter no matter how far you travel, you never have to be more than a few clicks away from all of your saved files.
Stream
ShareCenter devices work with a

Protect
Hard Drives Crash
If you're like most people, a lot of your digital life is stored on your computer. Your digital photos, home videos, music, work documents and more. But guess what. Hard drives crash, so isn't it time you backed yours up? And not just manually every so often with an external hard drive. We mean really back it up.
Enter ShareCenter
ShareCenter can be programmed to back up your digital content on a schedule or in real time so you can set it and forget it. Plus, ShareCenter can house more than one hard drive and can be configured to operate in the hard drive mode of your choice. It's truly a custom solution.
Feature Rich Backup Software
With ShareCenter's feature rich bundled software, you never have to worry about your hard drive crashing. Not only does it let you restore individual files and documents in case they get lost, it lets you take snapshots of your entire hard drive so you can restore your computer to exactly the way it was when the snapshot was taken.
ShareCenter devices allow you to easily create backup schedules and storage quotas for specific users and groups.
Manage
Simplified Management
Io ShareCenter solutions can do a whole lot. They let you back up your content, share it with friends and family, access everything remotely from the Internet and stream content to your TV. Thankfully, they're also incredibly easy to manage.
With included feature-rich backup software, Windows users can easily create schedules and rules including real-time, full or incremental backups and can set storage quotas for specific users and groups. All without breaking a sweat.
Network Access
ShareCenter storage enclosures support up to 64 unique users and allow you to add them to a group or individually, making it simple to manage who has access to what. Plus, you can easily give rights to specific users or groups and assign them to folders with either read or read/write permissions. This is perfect for the home where you can ensure your children will only have access to age appropriate material or for an office environment with employee-specific data.
Storage QuotasHate it when people fill up your hard drive with their photos and music? Want to save some space for your own stuff? Good news: ShareCenter supports storage quotas for both groups and individual users. That means you can easily limit the amount of storage users are allocated and change those quotas as necessary. With ShareCenter, you've got the power.
Hard Drive 101
3.5-inch SATA Hard Drives
3.5-inch SATA (Serial ATA) hard drives can be found easily right here on Amazon.com! As long as the hard drives you purchase are 3.5-inch SATA drives, they will work with your ShareCenter Device.
The Right Capacity for You
Hard drives come in a variety of storage capacities, generally ranging from 250 GB all the way up to 1 TB. Think of everything you want to store and back up on your ShareCenter device, including music, videos, photos and documents to decide on the best size for you:
| 250 GB Hard Drive | 500 GB Hard Drive | 1 TB Hard Drive |
|
|
|
The Right Number of Drives for You
 | You want to use your ShareCenter device for extra space to store your digital content and to share that content with all of the computers on your network. |
 | You want to store and share content over your network, but you also want to take advantage of RAID 1 technology to ensure that if one of the drives crashes, your content is still safe. |
 | You want to store and share content over your network with the 4-Bay ShareCenter device (DNS-343) and want to use RAID 5 technology because it offers the highest performance and the most reliable data recovery in the case of hard drive failure. |

2-bay network storage enclosure (DNS-321, diskless), power adapter, Ethernet cable, installation guide, CD-ROM with software and product documentation
- 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 dependant on the drive capacity of the lowest-sized drive. May not work with older generation SATA drives.
- D-Link cannot guarantee full compatibility or proper playback with all codecs. Playback compatibility depends on the codec support of the UPnP AV media player.
- Unless additional precautions are taken, use of an FTP Server to access files over the Internet does not provide for secure or encrypted transmissions. It is recommended that the end-user utilize a Virtual Private Network (VPN) to establish a secure FTP session.

Size Name:Diskless
I've been pleased with the reliability and performance of the DNS-321. I was hoping the Gigabit transfer speeds would be significantly faster, but it seems to top out at 14-16 MBps (MegaBytes per sec). This is on the upper end of most consumer NAS boxes, including D-Link's tried & true DNS-323.
Pros:
. Runs cool & quiet.
. Spins down the HD when idle to conserve power.
. Rock-solid operation (no reboots necessary in the month I've had it).
Cons:
. Larger drives (1TB and up) can get "stuck" at 94% during the format phase, but eventually it will complete.
. User permissions setup is clunky. This is common among consumer-level NAS boxes though.
. User access permissions are cleared on reboot :(
. No firmware update yet (v1.0). D-Link tech support says they've fixed most of the problems above and are testing the new firmware for public release. The cons are relatively minor to me, and once fixed in firmware, this will be a 5-star product.
Notes:
Opt for a low-power (and low-heat) HD to use in an external enclosure. Transfer rates on this generation of NAS will never approach the max throughput of HDs, so using a fast 7200rpm drive is a waste of money and power. Extra heat from the faster drives may cause issues down the road. Recommended low-power models are the Western Digital GreenPower and Samsung EcoGreen.
UPDATE 11/30/2008: D-Link has released firmware 1.01 which fixes the issue with access permissions being cleared on reboot. It also claims to support 1.5 TB hard drives.
[...]
UPDATE 5/8/2009: User account access control has an issue in all firmware versions, from the original 1.0 release to the latest beta. Basically the setting to allow All users to access a share disappears. Resetting to defaults sometimes brings it back, but shares configured to allow All users don't work properly. Weird issues with the All checkbox and shares disappearing are very frustrating. Dlink tech support has been aware of this for 4-6 months but no fix is in sight.
Final Update: D-Link finally fixed the issue with All Users permissions in firmware 1.03. There are some lingering issues, some minor and some not so minor, but D-Link hasn't released a firmware in well over a year. Looks like D-Link has written off this product.

Size Name:Diskless
Well, it was working fine for the features I was using. Immediately updated to their latest firmware release. Put 2 1TB drives in it, all the backup options (rebuild drive, etc.) seemed fine as I played around with swapping drives out. Then I tried to copy all of my current data over to this NAS box. After about a full day of copying (I have several hundred gigs of files) I went to check the status of the backup.
The backup had completed... HOWEVER, since I had turned on data validation (rereads the destination and source files and compares after the backup) it noted that out of the 1000s of files I had backed up that 12 of them were "not equivalent to the source files".
I took down the names of the files and then did a hex dump compare of the old and new files. To my surprise the files that were copied onto the NAS box had *exactly* 76 bytes of zero in very specific relative offsets in each file. It was always at hex offsets with the last 3 nibbles of the file offset being in the range of xfb4-xfff that were all zero, in all of the "corrupted" files.
Puzzled, I did some Google searching and found that there was a Linux kernel bug found at the end of 2006 that just happens to exactly match this behavior! The kernel was losing the "dirty bits" (modified memory page indicators) when it was writing to ext2 or ext3 file systems (this box uses ext2). This only happened on certain "chunks" (76 bytes for the Linux case) if they were the 76 bytes that fall at the end of a 4k memory page boundary (the last 76 bytes of a 4k page are... you guessed it!! bytes xfb4-xfff).
The data I was transferring was from a Windows XP machine and this NAS box is internally running.. yep, LINUX! I believe they likely have a version of kernel running on this thing that was silently corrupting my data, as all the issues seem to exactly match my conditions.
That is the WORST kind of data corruption ("silent") because there were NO error indications at ALL except for when it had done the final recompare, which good thing I had turned that on or I would have NEVER known my data was being corrupted as it was copied to this NAS box!
I notified the D-Link tech support people about this issue, and they responded back saying that they are looking into what is causing the problem (think I gave them a good enough head's up on this one!)
I promptly returned the box to get my money back and am now running w/ a RAID 1 configuration in my main PC instead of having an external NAS box.
Support notes - I stayed on the phone for the D-Link tech support number for a good 20+ minutes, all I got was the answering service kept repeating "due to a large volume of calls, ... " so I just hung up and emailed them instead. Took them about a week to get back to me (but they did).
Other gripes about the box - the little levers to remove the drives were REALLY hard to use, my thumb got sore after swapping the drives a couple times for doing the failed drive testing.
This review is specifically about the DNS-321 as that was the only one I tested, however the DNS-323 is VERY similar to this box (just basically added a print server), so I can't say if that one is any better or does the same corruption as this one does (it's quite possible).

Size Name:Diskless|Amazon Verified Purchase
I bought this to test as an inexpensive file server in a small business, so I cannot comment about the UPnP server, FTP server, etc.
The unit ships with firmware v1.00, but that firmware has problems (RAID, large drive, fan settings, etc.) that are well documented, but firmware v1.01 was released in October 2008, and was supposed to fix those issues.
I immediately updated the firmware to v1.01 and began to test the RAID for reliability, etc. It turns out that v1.01 broke some important items for me - most notibly the permissions. As soon as you create a single user, the ability to select "All accounts" disappears. Further, every time you reboot the unit, you will lose all of the permissions that you set up. This is a bug, and D-Link is well aware of it since early November 2008 - you can read about it on their forums. It is now early March 2009, and they have not released an updated firmware.
I have it turned off and sitting on the shelf waiting for a new version of the firmware. If they fix it, this could turn out to be a nice unit, but until then, stay away if you want a reliable file server with RAID for a small business.
