WD Purple Surveillance SATA Hard Drive

Surveillance Storage Built for Continuous Recording WD Purple gives compatible security recorders a hard drive designed around the way surveillance systems work: multiple cameras writing video for long periods, often around the clock. Its AllFrame firmware addresses the sustained, write-intensive demands of recording rather than treating video storage as an occasional desktop task. For shops, offices, homes and other monitored premises, that means a storage platform designed for the recorder at the centre of the system. Standard WD Purple and selected WD Purple Pro options are included in this listing. Both are internal SATA surveillance drives, but Pro adds capabilities for more demanding video analytics and higher workloads. Choose the appropriate tier using the recorder compatibility list, total recording workload and retention requirement. Highlights Purpose-built surveillance storage Designed for 24/7 recording with AllFrame technology. Up to 64 single-stream HD cameras, subject to recorder capability and recording settings. Match the drive to the workload Standard Purple: up to 180TB per year of transferred data. Pro: up to 550TB per year, AllFrame AI and analytics-stream support. Familiar integration and clear coverage CMR recording, a 3.5-inch form factor and a SATA 6Gb/s interface. Three-year limited warranty for standard Purple; five-year limited warranty for Pro. Key Features Built for an always-on recorderSurveillance recording places different demands on a drive from everyday desktop use. WD Purple is engineered for continuous operation, with multiple video streams arriving throughout the day and night. It is intended for compatible DVRs, NVRs and surveillance systems, where the drive must work alongside the recorder's storage controller, cooling and recording software. AllFrame firmware for streaming videoStandard Purple uses AllFrame technology to improve ATA streaming and help reduce frame loss during surveillance recording. This tuning targets the low-bitrate, write-intensive workloads typical of video systems. The recorder, network and camera settings still determine the complete recording path, so the drive complements a correctly designed system rather than replacing the need for sufficient recorder performance and bandwidth. Support for multiple camera streamsSupport for up to 64 single-stream HD cameras gives compatible recorders flexibility when cameras are added or recording schedules change. WD's camera-count test uses 1080p H.265 video at 25 frames per second and 3.2Mbps per stream. Higher resolution, frame rate or bitrate can change the practical limit. Match the drive and recorder to the actual cameras, rather than using camera count alone to size a system. Workload ratings that reflect recording and playbackStandard Purple is rated for up to 180TB per year of transferred data, while the Pro options are rated for up to 550TB per year. These annualised ratings include both data read and data written, making playback, review and exported footage relevant alongside continuous recording. Select a tier with sufficient workload allowance for how the system will actually be used. Pro capability for video analyticsThe Pro options use AllFrame AI to support up to 32 additional AI streams alongside the specified HD camera streams. They also provide a higher workload rating and WD Device Analytics support on compatible systems. AI streams are an analytics workload specification, not a promise that every recorder can connect extra cameras. Choose Pro when the host supports its capabilities and the application benefits from them. Features for compatible multi-bay systemsRotational vibration sensors and tarnish-resistant components are included on eligible standard models and on the Pro options. Standard drive-bay support varies with the selected drive; Pro does not specify a drive-imposed bay limit. The recorder's own qualification and thermal design remain essential when several drives operate together in one enclosure. Plan retention around the footageCMR recording and a familiar SATA connection make Purple a practical storage choice for a supported surveillance platform. Required retention depends on camera bitrate, recording hours, compression, event settings and the recorder's reserved space or RAID configuration. Check the usable storage requirement before choosing a drive, and keep an independent copy of footage that must survive recorder failure, accidental deletion or an incident at the premises. Manufacturer-backed coverageStandard Purple carries a three-year limited warranty and the Pro options carry five-year limited coverage, subject to applicable regional terms. Published MTBF values describe statistical reliability under WD's stated workload and temperature conditions; they do not specify an individual drive's service life. Regular health monitoring and a suitable recording-retention policy remain important parts of system operation. Summary WD Purple is a surveillance-focused internal hard drive for compatible recorders that need continuous video storage. Choose standard Purple for supported surveillance workloads, or a Pro option when the recorder, analytics requirements and annual data transfer justify the higher tier. Confirm compatibility, operating conditions and retention requirements before installation, then use the detailed specifications to match the drive to the system. 더 보기
