The Cost of a Lost Data Records
Disk drives rarely fail, but it is a fact of that it does happen. According to a 2010 study by
Parks Associates, it is estimated that every day 126,000 people in the U.S. and U.K.
lose data on their computers, and that two out of five PC users have lost digital files at
some point in their lives. The cost of lost data from computers to businesses can be
even more substantial as reliance on information and data as economic drivers for
businesses continues to increase. Hence, businesses must be proactive in protecting
this important resource.
This is the purpose for the BlackArmor NAS, to protect valuable business critical data
and to optimize uptime. This objective is achieved by BlackArmor NAS in that data is
spread across the four drives that run as a fault-tolerant RAID 5 array.
The Seagate® BlackArmor™ NAS 440 and NAS 420 are designed to help small
businesses prevent the negative impacts of data loss or corruption.
Part 1: Product Overview
Introduction
The Seagate® BlackArmor™ NAS 440 and NAS 420 are expandable network-attached
storage solutions that provide small business and small-office/home-office (SOHO)
organizations with a centralized, secure way to manage business-critical information and
data with easy-to-use features. It is perfect for small organizations that have little or no
IT support and for SOHO-based individuals who maintain their own hardware. The
Seagate BlackArmor NAS 440 and 420 network storage servers were originally
introduced in March 2009 and have since then been continually updated with new
firmware and greater capacities.
Ca acity and Pricing
The BlackArmor NAS 440,420 and 400 use the same enclosure, which houses up to
four hard drives. The NAS 440 ships with four Seagate Serial ATA (SATA) hard drives;
the NAS 420 ships with two and the NAS 400 ships without drives allowing the customer
to choose from a list of certified Seagate drive designed to meet varying business needs.
The 420 can be upgraded at any time by installing drives in the two open bays. These
configurations allow companies to choose the right amount of storage to meet their
immediate business needs and add more as their business grows.

Key Features
The Seagate BlackArmor NAS consists of four main components:
• BlackArmor Server: The actual hardware that includes main enclosure, disk
drives, and external power supply
• BlackArmor Discovery: Utility software that finds and connects the BlackArmor
NAS to a computer
• BlackArmor Manager: A browser-based tool embedded in the NAS to set up,
modify, and monitor the BlackArmor NAS locally or remotely
• BlackArmor Backup: A software application that backs up files, applications,
and even operating systems
Additionally, secure remote access is available via the Internet using the free Seagate
Global Access service. No software is required to use Seagate Global Access.
A fully self-contained, out-of-the box solution, the BlackArmor NAS on-board LCD screen
displays settings and status information. Compared with affordable NAS products from
other manufacturers, we believe the Seagate BlackArmor NAS 440, NAS 420, and NAS

400 each offer unparalleled security, accessibility and peace of mind, achieved through
several key features:
Dual Gigabit Ethernet Ports
High-end corporate enterprise-class storage systems and networks use multiple network
connections to assure uninterrupted operation should any port fail. At Seagate, we
believe this capability should be available to everyone. For that reason, the BlackArmor
NAS contains dual rear-panel Ethernet ports that allow users to:
• Connect both ports to the network for fail-safe operation should one port fail
• Connect one port to the network and connect the other port directly to a second
BlackArmor NAS to backup the primary unit automatically without consuming any
network bandwidth
The BlackArmor NAS features dual Ethernet ports that can be used to provide port failover
redundancy or direct connection to a second unit for NAS to NAS backup that bypasses the
network. Four USB ports (one located on the front panel) can be used to attach hard drives, share
a printer among users, or connect to an uninterruptible power supply data port to ensure a graceful
shutdown in the event of a power outage.
Four USB Ports
The one front-mounted and three rear-mounted USB 2.0 ports allow you to connect
external USB hard drives for additional storage, manage off-site data rotation, share a
USB printer, or connect a UPS (uninterrupted power supply) to safeguard against
sudden loss of electrical power.
External Power Supply
Any device with a single built-in power supply is out of business if that power supply
fails. It’s true for your microwave oven, television,
and even your desktop computer. In designing the
BlackArmor NAS, one of our guiding principles
was to assure that the data stored on it is
accessible at all times. Enterprise-class storage
sub-systems often have twin built-in power
supplies that draw electricity from separate power

cords, but that is a very expensive solution. In designing the BlackArmor NAS, we did
the next best thing: use an external power supply, exactly like a notebook computer
does. Should it ever fail, simply unplug and replace it with another one.
Using an external supply offers several benefits:
• Quick replacement ensures access to data with minimal downtime
• Heat generated by the power supply is kept away from electronics and drives
• The entire unit can be made smaller and lighter
• Ventilation is improved, helping to keep drives cool
Multiple Simultaneous RAID Levels
BlackArmor NAS supports creation of up to four logical volumes. Each volume can be
provisioned at a different RAID level of protection (RAID-0/1/5/10). To our knowledge,
this capability has never before been incorporated into a small-business NAS solution.
The reasons for setting up volumes with different levels of RAID protection should be a
function of the data it stores.
For example, data files that are crucial for running a business but where read/write
speeds are not a concern would be best served by RAID Level 5. Files that require
redundancy and faster read/write performance might be stored at RAID Level 1. For files
that require very fast performance, such as watching a downloaded movie stored on the
NAS, RAID Level 0, which improves performance but provides no fault tolerance may be
the best choice. With the Seagate BlackArmor NAS, it’s possible to provide all of these
RAID configurations simultaneously; it takes just a few minutes to set up. (Note: RAID 5
requires a minimum of three drives, though use of four is preferred. RAID 10 requires
four drives configured in mirrored pairs.)
The default RAID setting for the BlackArmor is RAID 5 for the BlackArmor NAS 440
server and RAID 1 for the BlackArmor NAS 220. This ensures the most reliable and
redundant back up of the data it contains.
Hot-Swappable Drives
All BlackArmor NAS products are user-serviceable and feature
hot-swappable drives to ensure uninterrupted operation. No
tools are required. Simply insert the spare or replacement drive
into the cradle and then slide the cradle into the drive bay.
Should a drive ever require replacement, hot swapping means
the unit need not be powered down. Additional drive cradles are
available for replacement or easy swap for archiving drives.
Though Seagate drives are known for their exceptional quality, it
is suggested that a company which cannot risk down time keep
a spare drive in a cradle ready for use on a moment’s notice.
It is important to note that different RAID levels provide differing
levels of protection and performance. The BlackArmor NAS 440 ships with RAID 5
already set up and the NAS 220 ships in a RAID 1 configuration. RAID 5 provides the
highest possible level of protection for data. Seagate strongly urges the use of RAID 5
Drive cradle

when three or more hard drives are present. For two-disk NAS 420 systems, Seagate
recommends RAID 1, in which contents of one drive are duplicated (mirrored) on the
second drive. Administrators should be especially aware that RAID 0 distributes data
across several disks in a way that yields improved performance, but that all data on all
disks is lost if any one disk fails.
High Security
With BlackArmor NAS, hardware-based encryption is possible for entire volumes,
folders, and even for an individual backed up file. This is accomplished with intuitive
software management for access control using a chipset that provides hardware
encryption. A bare metal restore and recovery CD to protect against data loss is
included. BlackArmor NAS supports HTTPS and allows for the import of an SSL
certificate to encrypt all communications with the device. HTTPS is fully support for
remote access via the free Seagate Global Access service.
Synchronization for Up to 50 Computers With BlackArmor Backup software, the
BlackArmor NAS delivers automatic and scheduled backup of business-critical data for
up to 50 networked computers on the 440/420 and up to 20 networked computers on the
220. This includes full-system backup and RAID options to provide duplication of data.
For any business with up to 50 computers, BlackArmor NAS is the perfect solution. The
NAS 440/420 ships with 10 client licenses and the BlackArmor NAS 220 ships with 5
licenses. However, additional licenses can be purchased through Seagate.com in 2 pack
and 5 pack bundles.

Designed for Growth
Not everyone or every small business needs 8TB of storage, even if a portion of that
amount is set aside for overhead in a RAID array. Small businesses and self-employed
individuals can start with a two-drive 2TB configuration (BlackArmor NAS 420 with two
1TB drives), and add more drives as their businesses and storage needs grow. The
Seagate BlackArmor NAS family of servers offers the ability to scale from 2TB to 8TB.
Remote Access – Accessibility from Anywhere
When away from the office, BlackArmor NAS users can use the Seagate Global Access
service to access and share content securely from any Internet-connected computer. No
software needs to be installed. With this capability, companies can invite colleagues and
clients to access select files and folders without needing an FTP site, while keeping the
firewall intact and maintaining the security of the network.
PC and Macintosh Support
The Seagate BlackArmor NAS 440.420/400/220 network servers support Microsoft®
Windows® XP, Windows 7, Windows Vista, and Apple® Mac OS® X 10.4.11 or later.
(The BlackArmor Backup software is not currently available for Mac OS.)

Tools for Systems Integrators
With the BlackArmor Discovery software, and the unit’s built-in management Web server
directly addressable through a local IP address, assigned automatically by DHCP or a
fixed address assigned manually (such as 192.168.1.xxx), managing the device is very
simple and straightforward. Key aspects of management are covered later in this
reviewer’s guide. Nevertheless, Seagate designed BlackArmor NAS with specific
capabilities for value-added resellers, solutions providers, and systems integrators.
Secure Remote Management
For integrators who plan to watch over BlackArmor NAS units on behalf of their
customers, this capability allows the integrator to monitor an unlimited number of
BlackArmor NAS units from a single location, without the need to make an in-person
visit. This capability is implemented through DDNS (Dynamic DNS).
Active Directory Support
BlackArmor NAS incorporates built-in support Microsoft® Active Directory®to populate users and
groups, Kerberos-based authentication, and DNS-based naming, and other network information.
When the BlackArmor is in Domain mode, it builds a list of domain users and groups. Using the
BlackArmor’s Manager page, user Access and Folder Share Permissions, each Active Directory
user from the list can be assigned to a Share (folder) that has already been created on the NAS.
The Share permissions (set in Manager Page only) are Full Access, Read Only and No Access.
Permissions are the same for Groups. When an Active Directory user boots their computer and
logs in to Windows with their Active Directory user name and password, assuming they already
have a short-cut or mapped drive letter to their share, the user can open their share without
having to put in their user name and password again.
In some larger businesses, multiple Active Directory servers are used. The BlackArmor NAS
products can only communicate with one at a time and currently do not support fail-over to a
backup Active Directory server. Child groups or groups within a group are also not supported at
this time, but may be available in a future firmware release.
What Can You Do With BlackArmor NAS?
The BlackArmor NAS is highly a versatile device that can be used to store, backup, and
share data. You can also stream music, videos, and movies. Uses include:
• Get up and running quickly with Quick start features
• Store files by using BlackArmor NAS as a central primary-storage repository.
• Easily view or map shared volumes to a computer, or back up the PC from which
you are working from, using the BlackArmor Discovery tool software, which
automatically displays all BlackArmor NAS products connected to the network.
• Share with colleagues and customers on a local network or over the Internet.
• Conduct full-system backup and recovery to help protect everything on your PC’s
hard drive including the operating system, programs and settings. In the event of
