WESTERN DIGITAL SURVEILLANCE WD20PURZ HARD DISK 2TB PURPLE Long Storage 12 months Low Power Consumption 4.6W Longer Lifespan for Security System CCTV Storage

Western Digital WD Purple 2TB Surveillance Hard Disk Singapore – WD20PURZ & WD23PURZ CCTV Storage

Reliable 24/7 Hard Drive Storage for CCTV DVR, NVR and Security Systems

The Western Digital WD Purple 2TB Surveillance Hard Drive is engineered specifically for continuous CCTV video recording in compatible DVR and NVR security systems.

Models such as the established WD20PURZ and current WD23PURZ are designed for write-intensive surveillance workloads, where video may be recorded continuously, 24 hours a day and seven days a week.

Unlike a standard desktop hard disk, WD Purple drives are developed for the heat fluctuations, vibration and constant recording demands commonly found inside CCTV recorders. Western Digital’s AllFrame technology is designed to reduce dropped video frames and improve recording and playback performance. (Western Digital)

Important storage clarification: A single 2TB hard disk does not automatically provide 12 months of CCTV retention. Actual recording duration depends on camera quantity, resolution, bitrate, frame rate, compression and recording mode.

WD20PURZ and WD23PURZ 2TB Surveillance HDD

Both model references belong to Western Digital’s WD Purple surveillance-storage family.

The WD20PURZ is an earlier 2TB surveillance-drive model commonly installed in existing CCTV recorders.

The WD23PURZ is a current 2TB WD Purple model listed by Western Digital with:

• 2TB storage capacity
• 3.5-inch form factor
• SATA interface
• CMR recording technology
• 64MB cache
• Transfer rate up to 175MB/s
• Three-year limited warranty

Western Digital lists both WD22PURZ and WD23PURZ as current 2TB variants, with different cache configurations. (Western Digital)

Key Features of WD Purple 2TB

Designed for 24/7 Surveillance Recording

WD Purple drives are engineered for always-on video-surveillance systems rather than occasional desktop-computer workloads.

They are suitable for continuous recording from:

• IP cameras
• Analogue CCTV cameras
• HD-TVI cameras
• HDCVI cameras
• AHD cameras
• Network video recorders
• Digital video recorders

Western Digital states that WD Purple drives are designed to operate in demanding 24/7 surveillance environments. (Western Digital)

AllFrame Technology

Western Digital’s proprietary AllFrame technology is designed for surveillance workloads involving continuous, low-bitrate and multi-stream video recording.

Its purpose is to help:

• Reduce frame loss
• Improve video recording
• Improve playback continuity
• Support multi-camera surveillance
• Optimise write-intensive workloads

(Western Digital)

Supports Multiple HD Cameras

Western Digital states that current WD Purple drives support up to 64 single-stream HD cameras, subject to recorder configuration and workload conditions. (Western Digital)

This specification describes platform capability, not guaranteed recording duration. A 2TB drive connected to 64 cameras would provide only limited retention because storage consumption increases with every camera.

Up to 180TB per Year Workload Rating

Current WD Purple models are rated for workloads of up to 180TB per year, which is designed to support the continuous data-writing requirements of mainstream DVR and NVR installations. (Western Digital)

CMR Recording Technology

The WD23PURZ uses Conventional Magnetic Recording, commonly known as CMR.

CMR is appropriate for sustained surveillance recording because data tracks are written conventionally without the overlapping-track structure associated with SMR technology. (Western Digital)

Low-Power Surveillance Storage

WD Purple drives are designed to provide efficient, reliable operation inside surveillance recorders.

Lower power consumption can help reduce:

• Internal recorder heat
• Electrical consumption
• Cooling demand
• Stress on the recorder power supply

Actual power consumption depends on the specific model and operating condition.

3.5-Inch SATA Hard Drive

The WD23PURZ is a standard 3.5-inch SATA surveillance HDD, making it compatible with many professional DVRs and NVRs that accept standard internal SATA storage.

Compatibility should always be confirmed against the recorder’s:

• Maximum HDD capacity
• Approved HDD list
• SATA-interface support
• Number of HDD bays
• Firmware version

Can a 2TB Hard Drive Store CCTV for 12 Months?

Usually, not for a normal multi-camera continuous-recording system.

A 2TB hard disk may provide:

• Several days for many high-resolution cameras
• Several weeks for a small system
• Several months only under highly reduced recording settings
• Up to 12 months only in exceptional low-data configurations

Twelve-month retention might require:

• One camera rather than many cameras
• Low resolution
• Low frame rate
• Low bitrate
• H.265 or H.265+
• Motion- or event-only recording
• Very limited daily activity
• Multiple hard disks or a larger storage array

Therefore, “2TB provides 12 months” should never be promised without a formal storage calculation.

Factors That Determine CCTV Storage Duration

Number of Cameras

Eight cameras consume approximately eight times the storage of one camera when all other settings are similar.

Camera Resolution

Higher-resolution cameras generally consume more storage:

2MP < 4MP < 5MP < 8MP < 12MP

Video Bitrate

Bitrate is one of the largest factors affecting storage. A camera configured at 4Mbps requires significantly more capacity than one operating at 1Mbps.

Frames per Second

Recording at 25fps or 30fps normally consumes more storage than 10fps or 15fps.

Compression

Modern compression such as H.265 and H.265+ can reduce storage requirements compared with older H.264 configurations.

Continuous vs Event Recording

Continuous recording stores video throughout the day. Motion- or event-based recording stores video only when a configured event occurs.

Scene Complexity

A busy road, moving machinery, rain or changing lighting can require more data than a quiet indoor corridor at the same nominal settings.

Example Storage Expectations

These are rough planning examples only:

Four 2MP Cameras

At moderate H.265 settings, a 2TB drive may provide several weeks of recording.

Eight 4MP Cameras

At higher bitrates and continuous recording, retention may be approximately one to two weeks, depending on configuration.

One Low-Bitrate Camera

A single camera using event recording and low bitrate may retain footage for several months.

A proper storage calculator should be used before quotation or installation.

Why Use a Surveillance HDD Instead of a Desktop Hard Disk?

A desktop hard disk is normally designed for intermittent computer use.

A CCTV surveillance drive is designed for:

• Continuous writing
• Multi-stream video
• DVR/NVR environments
• Higher operating hours
• Recorder vibration
• Video playback workloads

Western Digital specifically positions WD Purple for mainstream 24/7 video-surveillance systems rather than ordinary desktop usage. (Western Digital)

Suitable CCTV Applications

WD Purple 2TB hard drives are suitable for compatible:

• Hikvision DVRs and NVRs
• Dahua DVRs and NVRs
• TP-Link VIGI NVRs
• Uniview NVRs
• Hanwha recorders
• Axis recording servers
• Bosch surveillance systems
• i-PRO CCTV systems
• Home CCTV systems
• Retail security systems
• Office surveillance
• Warehouse CCTV
• Factory security systems

Recorder compatibility should be confirmed before installation.

CCTV HDD Repair and Replacement Singapore

Common signs of a failing surveillance hard drive include:

• HDD abnormal alarm
• No recording
• Missing footage
• Playback failure
• Recorder restarting
• Clicking or unusual HDD noise
• Disk not initialised
• Disk read/write error
• Storage full but not overwriting
• Slow playback
• Recorder becoming unstable

A hard-drive warning should be investigated promptly because continued operation may result in complete recording loss.

CCTV Hard Drive Replacement Procedure

A professional HDD replacement may include:

1. Checking the DVR or NVR model
2. Confirming supported HDD capacity
3. Reviewing existing disk health
4. Exporting important video where possible
5. Shutting down the recorder safely
6. Replacing the surveillance HDD
7. Initialising the new hard disk
8. Configuring recording schedules
9. Testing live recording and playback
10. Confirming overwrite and HDD alarms

Initialising a replacement hard disk will prepare it for the recorder and may erase any existing data on that drive.
