WESTERN DIGITAL 4TB WD44PURZ 6TB WD64PURZ 8TB WD85PURZ HARD DISK PURPLE Surveillance Security System CCTV Storage

The Western Digital WD23PURZ is a 2TB WD Purple surveillance hard disk engineered for continuous video recording in compatible CCTV DVR and NVR systems.

Unlike a general desktop hard drive designed for ordinary computer workloads, WD Purple is built for the continuous writing, heat fluctuations and vibration commonly found inside always-on surveillance recorders. Western Digital’s AllFrame technology is designed to optimise write-intensive, low-bitrate and high-stream-count CCTV workloads while helping reduce video-frame loss and improve playback. (Western Digital)

The WD23PURZ is suitable for homes, retail shops, offices, factories, warehouses, schools, commercial buildings and other sites requiring dependable local CCTV recording in Singapore.

Important clarification: A 2TB hard disk does not automatically provide 12 months of CCTV recording. Retention depends on camera quantity, resolution, bitrate, frame rate, compression and recording schedule.

WD23PURZ Key Specifications

The Western Digital WD23PURZ provides:

• 2TB storage capacity
• 3.5-inch form factor
• SATA interface
• CMR recording technology
• 64MB cache
• Transfer rate of up to 175MB/s
• Operating temperature from 0°C to 65°C
• Three-year limited warranty
• Support for surveillance systems with up to 64 HD camera streams
• Workload rating of up to 180TB per year
• Support for systems with up to 16 drive bays (Western Digital)

Designed for 24/7 CCTV Recording

CCTV recorders may write video continuously throughout the day and night.

This creates a very different workload from an ordinary desktop computer, where the hard disk may remain idle for long periods. WD Purple drives are engineered specifically for mainstream surveillance systems and continuous recording environments. (Western Digital)

Suitable recording applications include:

• Hikvision DVR and NVR
• Dahua DVR and NVR
• TP-Link VIGI NVR
• Uniview NVR
• Hanwha CCTV recorders
• Bosch surveillance systems
• Axis recording solutions
• i-PRO security systems
• Hybrid CCTV recorders
• IP camera recording systems

Compatibility must be checked against the recorder’s supported HDD capacity and approved drive list before installation.

AllFrame Surveillance Technology

Western Digital’s AllFrame firmware technology is optimised for continuous, write-intensive surveillance workloads.

It is designed to improve:

• Video-recording stability
• Multi-camera stream handling
• Playback continuity
• Frame-loss performance
• Continuous DVR/NVR operation

This makes the WD23PURZ more appropriate for security recording than a general-purpose consumer hard drive. (Western Digital)

CMR Recording Technology

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

CMR stores data using conventional, non-overlapping tracks and is suitable for sustained surveillance recording and rewriting workloads. Western Digital identifies the WD23PURZ as a CMR surveillance drive. (Western Digital)

Supports Up to 64 HD Cameras

Western Digital lists WD Purple mainstream surveillance drives as compatible with systems using up to 64 single-stream HD cameras. (Western Digital)

However, this does not mean a single 2TB drive can provide long retention for 64 cameras.

The maximum number of connected cameras and the number of days recorded are different calculations:

Camera support refers to workload capability.

Storage retention refers to how long footage remains before being overwritten.

A 2TB drive supporting many camera streams may retain only a short period of footage if all cameras record continuously at high bitrate.

Can WD23PURZ Store CCTV for 12 Months?

A 2TB WD23PURZ can technically retain 12 months only under extremely low-storage configurations, such as:

• One camera
• Low resolution
• Very low bitrate
• Low frame rate
• Motion-only recording
• Limited daily activity
• Efficient H.265 or H.265+ compression

For a typical multi-camera system recording continuously, 2TB is unlikely to provide 12 months of storage.

A proper CCTV storage calculation should consider:

Camera Quantity × Bitrate × Daily Recording Hours × Retention Days

For genuine 12-month retention, the system may require larger-capacity drives, multiple HDDs, RAID storage, network storage or an archive server.

Factors Affecting Recording Duration

Number of Cameras

More cameras create more video data. Eight cameras generally require substantially more storage than one camera using similar recording settings.

Resolution

Higher-resolution cameras normally consume more storage:

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

Bitrate

Bitrate directly affects recording capacity. A camera recording at 4Mbps consumes approximately four times the storage of a camera recording at 1Mbps.

Frame Rate

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

Video Compression

H.265 and manufacturer-enhanced technologies such as H.265+ can reduce storage requirements compared with older H.264 configurations.

Continuous or Event Recording

Continuous recording stores video throughout the day. Motion or event recording stores footage only when activity is detected.

Low-Power CCTV Storage

WD Purple drives are designed for efficient surveillance operation, helping control power consumption and internal recorder heat.

Lower drive power consumption can help reduce:

• DVR/NVR internal temperature
• Cooling demand
• Electrical consumption
• Stress on the recorder power supply

Actual power usage depends on drive activity and recorder operating conditions.

WD23PURZ for CCTV Repair and Replacement

The WD23PURZ can be considered when an existing CCTV recorder shows:

• HDD abnormal warning
• No recording
• Missing video footage
• Playback failure
• Disk not detected
• Read/write error
• Recorder restarting
• Unusual HDD noise
• Storage full but not overwriting
• Slow or unstable playback

A failing HDD should be inspected promptly because continued operation may result in complete recording loss.

Professional CCTV HDD Replacement

A proper hard-disk replacement may include:

1. Confirming the DVR or NVR model
2. Checking its maximum supported HDD capacity
3. Testing the existing drive’s health
4. Exporting important footage where possible
5. Shutting down the recorder safely
6. Installing the WD23PURZ
7. Initialising the hard disk in the recorder
8. Configuring recording and overwrite settings
9. Testing live recording
10. Verifying playback and HDD alarm status

Initialising a hard disk usually erases its existing data. Important recordings should be exported before replacement whenever possible.

Ideal Applications

The WD23PURZ 2TB surveillance hard drive is suitable for compatible systems installed in:

• Homes and HDB flats
• Retail shops
• Offices
• Restaurants
• Schools
• Clinics
• Warehouses
• Factories

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

WESTERN DIGITAL 4TB WD44PURZ 6TB WD64PURZ 8TB WD85PURZ HARD DISK PURPLE Surveillance Security System CCTV Storage

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.

WESTERN DIGITAL 4TB WD44PURZ 6TB WD64PURZ 8TB WD85PURZ HARD DISK PURPLE Surveillance Security System CCTV Storage

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)
