{"product_id":"wd-purple-pro","title":"WD Purple Pro Surveillance SATA Hard Drive","description":"\u003ch2\u003eKeep surveillance recording and analytics moving together\u003c\/h2\u003e \u003cp\u003eA busy surveillance system does more than save video. It records new footage, retains events for review and supplies streams for analytics, often at the same time. WD Purple Pro is an internal SATA hard drive developed for these demanding smart-video workloads. Its AllFrame AI firmware, CMR recording and continuous-duty design suit compatible advanced recorders, video management systems and video-storage servers, helping you build the storage foundation around the way your installation captures and uses footage.\u003c\/p\u003e \u003ch2\u003eHighlights\u003c\/h2\u003e \u003ch3\u003eBuilt for continuous smart video\u003c\/h3\u003e \u003cul\u003e \u003cli\u003eAllFrame AI firmware helps manage video, image and metadata streams.\u003c\/li\u003e \u003cli\u003eUp to 64 HD camera streams and 32 AI streams in compatible systems.\u003c\/li\u003e \u003c\/ul\u003e \u003ch3\u003ePerformance for recording and review\u003c\/h3\u003e \u003cul\u003e \u003cli\u003e7200 RPM CMR design with a SATA 6Gbps connection.\u003c\/li\u003e \u003cli\u003eA workload rating up to 550TB per year supports intensive video-storage planning.\u003c\/li\u003e \u003c\/ul\u003e \u003ch3\u003eA foundation for managed deployments\u003c\/h3\u003e \u003cul\u003e \u003cli\u003eRotational-vibration sensors and tarnish-resistant components.\u003c\/li\u003e \u003cli\u003eWDDA health insights on supported systems and a five-year limited warranty.\u003c\/li\u003e \u003c\/ul\u003e \u003ch2\u003eKey Features\u003c\/h2\u003e \u003ch3\u003eAllFrame AI for more than the main video stream\u003c\/h3\u003e \u003cp\u003eModern surveillance cameras can generate high-resolution video alongside images and metadata used to identify relevant events. AllFrame AI is designed to guide those streams to disk while helping reduce dropped frames. That matters when a compatible recording platform must continue capturing activity while its analytics processes examine other data. The drive provides the storage capability; object detection, recognition and other AI functions still come from the cameras, recorder or analytics software rather than being performed by the hard drive.\u003c\/p\u003e \u003ch3\u003eRecording and analytics on a compatible platform\u003c\/h3\u003e \u003cp\u003eSupport for up to 64 HD camera streams and 32 AI streams gives system designers a defined starting point for a demanding recorder. The camera rating is based on a single 3.2Mbps stream per camera at 1080p using H.265 and 25 frames per second. Higher resolution, different codecs, additional streams and increased bitrates change the workload. Check the recorder’s own channel, throughput and compatibility limits as well as the drive rating before deciding how many cameras the complete system can serve.\u003c\/p\u003e \u003ch3\u003eCMR storage for sustained video traffic\u003c\/h3\u003e \u003cp\u003eConventional magnetic recording and a 7200 RPM spindle speed provide a storage platform for continuous video workloads. The SATA interface connects the drive to a supported internal recorder or server bay, while cache and internal transfer performance depend on the drive version. Treat the interface link rate and the drive’s actual transfer performance as different measurements. Recording, playback, concurrent analysis and the host controller all influence the performance you see in an installed system.\u003c\/p\u003e \u003ch3\u003ePlan around the complete yearly workload\u003c\/h3\u003e \u003cp\u003eThe annualised workload rating covers up to 550TB of data transferred to or from the drive, rather than recording writes alone. Include playback, export, review and analytics reads when estimating the storage traffic your system will create. Retention planning also needs the total camera bitrate, daily recording schedule, event rules and required number of days. Those inputs provide a more useful basis for selecting storage than camera count by itself, especially where evidence must remain accessible for longer periods.\u003c\/p\u003e \u003ch3\u003eDesigned for demanding multi-drive environments\u003c\/h3\u003e \u003cp\u003eRotational-vibration sensors help the drive respond to vibration in systems containing several hard drives, while tarnish-resistant components suit demanding storage environments. WD specifies no drive-bay count limit at the drive-family level, but that does not remove the enclosure’s own limits or compatibility requirements. The recorder or server still needs appropriate mounting, power, airflow and validated drive support. Drive construction also varies by version, so family features should not be read as an identical mechanical design across every choice.\u003c\/p\u003e \u003ch3\u003eHealth information that supports maintenance planning\u003c\/h3\u003e \u003cp\u003eWestern Digital Device Analytics, or WDDA, supplies drive-health information and recommendations through a compatible recorder or system. This gives an administrator another input when deciding whether to investigate a drive or plan maintenance, alongside the platform’s own alerts and recordings. WDDA requires host support and does not guarantee that every fault will be predicted. Keep an appropriate backup or export process for important evidence; health monitoring and RAID resilience do not replace a separate copy.\u003c\/p\u003e \u003ch3\u003ePractical installation and thermal planning\u003c\/h3\u003e \u003cp\u003ePurple Pro needs a compatible 3.5-inch SATA drive bay with SATA data and suitable power connections. It is an internal component for a recorder or server, so check the exact drive against the host’s supported-model and capacity list before installation. Allow sufficient cooling for continuous service and follow the applicable drive temperature limits. The published weight describes the bare drive, and the power figures in the technical table are manufacturer averages rather than a complete system power-supply sizing guarantee.\u003c\/p\u003e \u003ch3\u003eReliability ratings with useful conditions\u003c\/h3\u003e \u003cp\u003eThe five-year limited warranty provides a clear manufacturer support period, subject to regional terms. The family’s statistical MTBF ratings describe a drive population under stated conditions; they are not a promise that an individual unit will operate for that many hours. Workload and temperature affect those estimates. For a surveillance deployment, combine the drive’s ratings with sensible cooling, system monitoring, maintenance and an evidence-protection policy appropriate to the site, rather than relying on a single reliability figure.\u003c\/p\u003e \u003ch2\u003eSummary\u003c\/h2\u003e \u003cp\u003eWD Purple Pro is a strong fit for compatible surveillance installations that combine continuous recording, footage review and demanding analytics workloads. AllFrame AI, CMR recording, defined stream support and a higher annual workload rating provide useful tools for planning the storage layer, while supported health monitoring and a five-year limited warranty help inform ongoing operation. Match it to the recorder, retention target and operating conditions to build a system around the footage you need to keep.\u003c\/p\u003e","brand":"WD","offers":[{"title":"8TB","offer_id":41465267290171,"sku":"WD8002PURP","price":759.0,"currency_code":"SGD","in_stock":true},{"title":"10TB","offer_id":41465267322939,"sku":"WD102PURP","price":949.0,"currency_code":"SGD","in_stock":true},{"title":"12TB","offer_id":41465267421243,"sku":"WD122PURP","price":1139.0,"currency_code":"SGD","in_stock":true},{"title":"14TB","offer_id":41465267454011,"sku":"WD142PURP","price":1329.0,"currency_code":"SGD","in_stock":true},{"title":"18TB","offer_id":41465267486779,"sku":"WD181PURP","price":1975.0,"currency_code":"SGD","in_stock":true},{"title":"22TB","offer_id":41465267519547,"sku":"WD221PURP","price":2385.0,"currency_code":"SGD","in_stock":true},{"title":"24TB","offer_id":41962514382907,"sku":"WD241PURP","price":2599.0,"currency_code":"SGD","in_stock":true},{"title":"26TB","offer_id":41962514415675,"sku":"WD260PURP","price":2765.0,"currency_code":"SGD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0557\/4541\/3179\/files\/wd-purple-pro-surveillance-sata-hard-drive-9820011.png?v=1791530175","url":"https:\/\/aceperipherals.com\/ja\/products\/wd-purple-pro","provider":"ACE Peripherals","version":"1.0","type":"link"}
