Western Digital WD 4TB Purple Surveillance Edition 64MB SATA3 HDD

The WD Purples are part of the WD hard drive family which consists of
five different colours: blue, green, purple, red and black. They all
have different purposes and while they are all quite similar, they are
all fine tuned to perform a particular task or be fit for a certain
type of application. The WD Purples are designed for endurance, built to
work non stop and constantly writing data without any loss in quality.
It features AllFrame which helps prevent video stutter or loss of image,
giving you extra protection for your important footage. The speed of
which these drives spin at are determined by Intellipower, which is WDs
optimzed speed to power ratio for the drives, ranging from 5400 to 7200
rpm, making these drives a lot more efficient. If you are after a drive
which can withstand long usage such as a surveillance system, the WD
purples would be the perfect choice.

The smart choice for surveillance

WD
Purple Surveillance Storage offers exclusive AllFrame technology to
bring you premium reliability and peace-of-mind when installing your
home or small to medium business security system. WD Purple’s exclusive
firmware upgrades work with ATA streaming to reduce error pixilation and
video interruptions that occur when desktop hard drives are incorrectly
used as storage in security systems. WD Purple Surveillance Storage is
built for 24/7, always-on, high-definition surveillance security systems
that use up to eight hard drives and up to 32 cameras.

Choose a drive that is designed and engineered for home and business
surveillance systems and enjoy the peace-of-mind you can only get from a
surveillance-class hard drive.

Desktop drives vs. surveillance-class storage

You
wouldn’t use a bicycle to transport cargo across the country because
it’s not the right tool for the job. You also shouldn’t use a desktop
hard drive in your surveillance security system because it wasn’t
designed for that application.

WD Purple surveillance-class storage has been tested to be compatible
in a wide-range of security systems. These drives are designed to
replace standard desktop drives that were not designed for the harsh
24/7 always-on, high-definition surveillance environment. Desktop drives
are built to run for only short intervals and are not engineered to
withstand high-temperature fluctuations and equipment vibrations found
in a typical surveillance application.

Surveillance storage for peace-of-mind

Whether
you’re protecting your personal assets and loved ones or monitoring the
business you worked hard to build, you can rely on surveillance-class
storage built by one of the largest hard drive manufacturers in the
world. WD Purple Surveillance Storage is designed for high temperature,
always-on, surveillance security systems to ensure reliability and
quality video play back when you need it most. Experience the security
of knowing you’re using a surveillance-class drive designed by a leader
in the hard drive industry.

Improve performance with AllFrame

WD
Purple surveillance-class hard drives are equipped with AllFrame
technology which works with ATA streaming to reduce frame loss, improve
playback and increases the number of drive bays supported. AllFrame
reduces video interruptions that commonly occur when desktop hard drives
are incorrectly used as storage in security systems. Missed frames and
lost footage is a serious problem when an event occurs and surveillance
footage needs to be retrieved. WD Purple with AllFrame provides the
confidence you should expect when it’s time to play back and review
critical surveillance footage.

Engineered for compatibility

WD
Purple surveillance hard drives are built for compatibility with
industry-leading chassis and chip set manufacturers for seamless
integration into your new or existing video surveillance system. Check

right for you.

Lower power consumption

Low
power consumption is crucial in high-temperature always-on surveillance
environments. With exclusive IntelliSeek technology, WD Purple drives
calculate the optimum seek speeds which lowers power consumption, noise
and vibration that can damage and cause desktop drives to wear out more
quickly. When you invest in a premium surveillance-class drive you worry
less while enjoying the benefits over a longer period of time.

Optimized performance for up to 32 HD cameras

WD
Purple hard drives are optimized to support up to 32 high-definition
surveillance cameras, giving you the flexibility to upgrade and expand
your security system in the future.

storage products with a 3-year limited warranty worldwide.
