WD Purple PR1334M Description and Features

1.0 DESCRIPTION AND FEATURES

1.1 General Description

WD Purple Surveillance Storage is built for 24/7 always-on surveillance in high­definition security systems that utilize higher hard drive bay counts and up to 64
cameras. Exclusive AllFrame 4K™ technology works with ATA streaming to reduce
error pixilation and video interruptions that occur when desktop hard drives are
incorrectly used as storage in security systems.

1.2 Product Features

• Serial ATA (SATA) — Serial ATA (SATA) is the industry standard bus interface for

hard drives. It is designed to replace Parallel ATA, and has many advantages
including increased transfer rate, improved signal integrity, enhanced data pro­tection, and hot plug support.

• AllFrame 4K™ — All WD Purple™ drives are equipped with AllFrame 4K™ tech-

nology, which improves ATA streaming to help reduce frame loss, improve overall
video playback, and increase the number of hard drive bays supported within a
NVR. Help make your surveillance solution future-ready knowing that WD Purple™
drives are ready for ultra high definition cameras.

• Premium Protection -- Designed with tarnish-resistant components, this WD Pur-

ple drive offers premium protection in harsh environments where surveillance sys­tems may be installed.

• IntelliSeek™ — Calculates optimum seek speeds to lower power consumption,

noise, and vibration.

• Dynamic Fly Height Control — Designed to compensate for head/media separa-

tion changes due to temperature and altitude. This feature adds video quality
margins across temperature and altitude changes.

• Perpendicular Magnetic Recording (PMR) — With PMR technology the magneti-

zation of each data bit is aligned vertically to the spinning disk, rather than longi­tudinally as has been the case in hard drive technology for decades. This enables
more data on a given disk than is possible with conventional longitudinal record­ing, and provides a platform for future expansion of hard drive densities.

• NoTouch™ Ramp Load Technology — The recording head never touches the disk

media ensuring significantly less wear to the recording head and media as well as
better drive protection in transit.

• Dual Stage Actuator Technology — A head positioning system with dual-stage

actuators that improves positioning accuracy over the data track(s). The primary
stage provides course displacement; the secondary stage uses piezo electric
motion to fine tune the head positioning to a higher degree of precision.

• Advanced Format (AF) — Technology adopted by WD and other drive manufac-

turers as one of multiple ways to continue growing hard drive capacities. AF is a
more efficient media format that enables increased areal densities.

• Native Command Queuing (NCQ ) — Performance of a random I/O workload can

be improved through intelligent re-ordering of the I/O requests so they read/
write to and from the nearest available sectors and minimize the need for addi­tional disk revolutions or head actuator movement. This improvement can be
achieved though Native Command Queuing (NCQ ), which is supported by these
hard drives.

Description and Features WD Purple PR1334M

• Pre-emptive Wear Leveling (PWL) —This WD feature provides a solution for pro-
tecting the recording media against mechanical wear. In cases where the drive is
so busy with incoming commands that it is forced to stay in a same cylinder posi­tion for a long time, the PWL control engine initiates forced seeks so that disk
lubricant maintains an even distribution and does not become depleted. This fea­ture ensures reliability for applications that perform a high incidence of read/
write operations at the same physical location on the disk.

• S.M.A.R.T. Command Transport (SCT) — The SCT Command Transport feature set

provides a method for a host to send commands and data to a device and for a
device to send data and status to a host using log pages.

• World Wide Name (WWN) — The World Wide Name (WWN) defined in ATA/

ATAPI-7 is a modification of the IEEE extended unique identifier 64 bit standard
(EUI-64) and is comprised of three major components: naming authority, organiza­tionally unique identifier (OUI) and serial number. WD's OUI is 0014EEh.

• Reliability Features Set-Data Lifeguard™ — Representing WD's ongoing commit-

ment to data protection, Data Lifeguard includes features that enhance the drives
ability to prevent data loss. Data Lifeguard data protection utilities include ther­mal management, an environmental protection system, and embedded error
detection and repair features that automatically detect, isolate, and repair prob­lem areas that may develop over the extended use of the hard drive. With these
enhanced data reliability features, the drive can perform more accurate monitor­ing, error repair, and deliver exceptional data security.

• Hot Plug Support — SATA supports hot plugging (also known as “hot swapping”),

the ability to swap out a failed hard drive without having to power down the sys­tem or reboot. This capability contributes to both data availability and service­ability without any associated downtime, making it a critical feature for extending
SATA into enterprise applications.

• Active LED Status — The drive supports external LED requirements. It provides an

activity LED output which is ON during command execution and OFF otherwise.

• Fluid Dynamic Bearings (FDB) — Bearing design that incorporates a layer of high-

viscosity lubricant instead of ball bearings in the hard drive spindle motor. As an
alternative to conventional ball bearing technology, FDB designs provide
increased non-operational shock resistance, speed control, and improved acous­tics.

• Staggered Spin-Up — SATA 3 Gb/s feature that allows the system to control

whether the drive will spin up immediately or wait until the interface is fully ready
(available for specific OEM configurations).

• CacheFlow™ —WD’s unique, multi-generation caching algorithm evaluates the

way data is read from and written to the drive and adapts “on-the-fly” to the opti­mum read and write caching methods. CacheFlow minimizes disk seek operations
and overheads due to rotational latency. CacheFlow supports sequential and ran­dom write cache. With write cache and other CacheFlow features, the user can
cache both read and write data. The cache can hold multiple writes and collec­tively write them to the hard disk.

• 48-bit Logical Block Addressing (LBA) — WD SATA drives support both 48-bit

and 28-bit LBA and CHS-based addressing. LBA is included in advanced BIOS and
operating system device drivers and ensures high capacity disk integration.

WD Purple PR1334M Description and Features

• Power Management — The drive supports the ATA and SATA power management
command set, allowing the host to reduce the power consumption of the drive
by issuing a variety of power management commands.

• Self-Monitoring, Analysis, and Reporting Technology (S.M.A.R.T.) — S.M.A.R.T.

enables a drives internal status to be monitored through diagnostic commands at
the host level and during offline activities. S.M.A.R.T. devices employ data analysis
algorithms that are used to predict the likelihood of some near-term degradation
or fault conditions. When used with a S.M.A.R.T. application, the drive can alert
the host system of a negative reliability status condition. The host system can
then warn the user of the impending risk of data loss and recommend an appro­priate action.

• ATA Security — The drive supports the ATA Security Mode Feature set. The ATA

Security Mode feature set allows the user to create a device lock password that
prevents unauthorized hard disk access even if the drive is removed from the host
computer. The correct password must be supplied to the hard drive in order to
access user data. Both the User and Master Password features are supported,
along with the High and Maximum security modes. The Master Password Revision
code is also supported. This feature varies by drive configuration and may not be
available on all configurations.
