D-Link DNS-321 Network Attached Storage Enclosure
The D-Link 2-Bay Network Storage Enclosure (DNS-321) is the perfect way to store, share, and safeguard your documents, music, videos, and photos. With the D-Link tool-less installation, easily insert up to two SATA drives1 without any tools or attaching any cables. Additionally, the built-in UPnP™ AV media server enables streaming of digital content to compatible network media players (such as those found in the D-Link MediaLounge™ product line) as well as popular media player applications used in computers.
Protection And Performance
The availability of four different hard drive modes (Standard, JBOD, RAID 0, and RAID 1) allows you to choose the configuration best suited for your needs. Standard mode creates two separately accessible hard drives. JBOD combines both hard drives into one for maximum space efficiency. RAID 0 combines all drives in a ‘striped’ configuration, splitting data evenly across the hard disk drives to provide the highest performance, while RAID 1 causes the drives to mirror each other, providing maximum protection. If one drive fails while configured as RAID 1, the unaffected drive will continue to function as a single drive until the failed drive is replaced.
Simplified Management
With the included feature-rich Memeo™ software, you can create schedules and rules including real-time full or incremental backups. The Web-based configuration software allows users to establish storage quotas for specific users and groups. The DNS-321 can automatically back up your data regardless of the Operating System (OS) of your computer (Windows®, Mac®, or Linux®). The DNS-321 also features a built-in FTP server to access files through the Internet.
With its sleek design and quiet cooling fans, the DNS-321 can be easily placed on your desk at home or in the office. Utilizing SATA hard drives and gigabit connectivity, the 2-Bay Network Storage Enclosure (DNS-321) is a high performance, cost-effective solution for your home or small office data storage needs.

I was looking into some ''home server'' units by other companies. The DNS-321 provides all the basic features that I needed for my Apple computers (still working out the Time Machine backup solution). The administrative features are great for inexperienced users and for the power users out there, the box is easily hackable so you can add even more features. Very happy with my purchase and the support provided by D-Link.

I've been running this for over a year now with two 1TB WD drives in it. It's a good NAS to buy but it does get a bit quirky when changing some of the settings away from default. I haven't tried updating it's firmware and that might be the problem. But, running default settings with a set IP is VERY stable and consistent. I'm actually thinking about buying another one for more storage space.

This is a great little NAS. I stuck in 2 1TB drives. I also had problems during the formating step having the interface freeze at 94% complete like mentioned by others. But it did complete the formatting. The web interface works well for managing the DNS 321. This may not be the easiest device to set up if you limited experience with networking but I can't imagine how it could be made simpler.
The device is quiet and if it not being used the disks can be can be configured to spin down to conserve power. Of course its not going to be as fast as a native disk because everything is going across the network. All in all I am very satisfied.

Added two 1T HD and ran in RAID-1, plug the ethernet cable and turn on the power. It works. The DNS-321 rocks!

Been running 321 for 2 years on a backup battery. Using a pair of 500GB HDs. No physical issues like overheating. Boot up is kind of slow at 50 plus seconds. Shutdown is much faster at less than 10 seconds. No problems setting up jumbo frame rates between 321 and DL655 router. Large file transfer rates of 10 to 13 MB per sec using gigabit cards and CAT6 cables.
What is RAID?
RAID is an acronym first defined back in 1987 to describe a redundant array of
inexpensive disks, a technology that allowed computer users to achieve high
levels of storage reliability from low-cost PC hard disk drives, via the
technique of arranging the devices into an array for fail-safe redundancy.
"RAID" is now used as an umbrella term for computer data storage schemes that
can divide and replicate data among multiple hard disk drives. The different
schemes/architectures are named by the word RAID followed by a number, as in
RAID 0, RAID 1, etc. RAID's various designs involve two key elements: increased
data reliability or increased input/output performance. When multiple physical
disks are set up to use RAID technology, they are said to be in a RAID array.
This array distributes data across multiple disks, but the array is seen by the
computer user and operating system as one single disk. RAID can be set up to
serve several different purposes.
Organizing disks into a redundant array decreases the total usable storage
capacity. For instance, a 2-disk RAID 1 array loses half of the total capacity
that would have otherwise been available using both disks independently, and a
RAID 5 array with several disks loses the capacity of one whole disk. Other
types of RAID arrays are arranged so that they are faster to write to and read
from than a single disk.
There are various combinations of these
configurations giving different trade-offs and benefits of protection against
data loss, capacity, and speed. RAID levels 0, 1, and 5 are the most commonly
found, and cover most of the typical requirements.
RAID 0 (striped disks) distributes data
across several disks in a way that gives improved speed at any given instant. If
one disk fails, however, all of the data on the array will be lost, as there is
neither parity nor mirroring.
RAID 1 mirrors the contents of the
disks, making a 1:1 (1 to 1) ratio real-time backup. The contents of each disk
in the array are identical to that of every other disk in the array.
RAID 3 uses a striped set with
dedicated parity or bit interleaved parity or byte level parity. This
mechanism provides fault tolerance similar to RAID 5. However, because the strip
across the disks is a lot smaller than a file system block, reads and writes to
the array perform like a single drive with a high linear write performance. If
one drive fails, the performance doesn't change.
RAID 5 (striped disks with parity)
combines three or more disks in a way that protects against data loss of any one
disk. The storage capacity of the array is reduced by the capacity of the one
disk (all disks are of equal size).
RAID 6 (striped disks with dual parity)
can recover from the loss of two disks.
RAID 10 (or 1+0) uses both striping and
mirroring. ("01" or "0+1" is sometimes distinguished from "10" or "1+0": a
striped set of mirrored subsets and a mirrored set of striped subsets are both
valid, but distinct, configurations.)
