Built with AllFrame 4K technology, the drive reduces frame loss and improves playback smoothness when managing multiple video streams simultaneously, supporting up to 64 cameras on a single drive.\u003c\/p\u003e\n\u003cp\u003eThis drive is sold as a refurbished unit ('clean pull'), meaning it has been removed from a working system, tested for functionality, and cleared of previous data. The WD Purple series uses firmware tuned for write-intensive surveillance workloads rather than the mixed read\/write patterns of desktop computing, reducing wear on the drive mechanism when recording continuous streams. The 500GB capacity provides approximately 40-60 hours of 1080p recording depending on codec, bitrate and frame rate settings.\u003c\/p\u003e\n\u003cp\u003eThe drive measures 147mm × 101.6mm × 26.1mm (standard 3.5\" form factor) and weighs 460g. It connects via SATA III interface and draws 0.60A on 5V and 0.45A on 12V rails during operation. The label visible in the product image shows the WD Purple branding, 500GB capacity marking, and the drive's specific model and serial numbers for traceability.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Net Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e0.46\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Gross Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e0.46\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Length (mm)\u003c\/td\u003e\n\u003ctd\u003e150\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Width (mm)\u003c\/td\u003e\n\u003ctd\u003e100\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Height (mm)\u003c\/td\u003e\n\u003ctd\u003e30\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch5\u003eDownloads\u003c\/h5\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/products_HD500SACP_datasheet.pdf\" target=\"_blank\"\u003eProduct Specification Sheet\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eIs this drive new or refurbished?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThis is a refurbished drive, described as a 'clean pull'. It has been removed from a working system, tested for functionality, and wiped of previous data. Refurbished surveillance drives are commonly used in budget CCTV installations and as replacement drives in existing recorder systems.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow much recording time does 500GB provide?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eRecording time depends on resolution, codec, bitrate and frame rate. As a rough guide, 500GB stores approximately 40-60 hours of 1080p H.264 footage at standard bitrates (4-6 Mbps), or 15-25 hours of 4K footage. Lower-resolution cameras or reduced frame rates extend this significantly.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat's the difference between WD Purple and a standard desktop drive?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eWD Purple uses firmware optimised for continuous write operations typical of surveillance recording, reducing wear and frame drops when handling multiple camera streams. Desktop drives are tuned for mixed read\/write activity and may struggle under 24\/7 recording loads.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat interface does it use?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe drive uses a SATA III interface and fits standard 3.5\" drive bays in DVRs, NVRs and desktop PCs. It requires both a SATA data cable and a SATA power connector from the recorder or PC power supply.\u003c\/p\u003e","brand":"ESP","offers":[{"title":"Default Title","offer_id":45294167589131,"sku":"HD500SACP","price":109.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/HD500SACP_0ba76422-4178-4518-9596-27eb3cb7d583.jpg?v=1714669029","url":"https:\/\/niori.co.uk\/products\/wd-purple-500gb-surveillance-hard-drive-3-5-sata","provider":"Niori","version":"1.0","type":"link"}
