Built on Western Digital's AllFrame 4K technology, the drive supports up to 64 camera streams simultaneously and is rated for an annual workload of up to 180TB, making it suitable for medium-to-large surveillance installations running multiple high-resolution cameras.\u003c\/p\u003e\n\u003cp\u003eDesigned for multi-bay NVR chassis and dedicated surveillance recorders rather than desktop PCs, the WD Purple optimises read\/write behaviour for continuous streaming video rather than random access typical of general-purpose drives. The drive operates on a SATA III 6Gb\/s interface with 256MB cache and spins at 5400rpm, balancing sustained write performance with lower power draw and heat output over 24-hour operation.\u003c\/p\u003e\n\u003cp\u003eThe 8TB capacity provides approximately 60-90 days of retention for a typical 16-camera system recording at 1080p resolution with H.264 compression, or 30-45 days for 4K streams, depending on motion activity and bit rate settings. The drive measures 147mm length x 101.6mm width x 26.1mm height (standard 3.5-inch form factor) and weighs 690g, fitting standard drive bays in most commercial NVR chassis.\u003c\/p\u003e\n\u003cp\u003eWD's AllFrame technology reduces frame loss and improves overall video playback by optimising the drive's error recovery controls for streaming video workloads. The drive operates on 12V and 5V DC supply (SATA power connector) and is rated for operation in ambient temperatures up to 65°C, typical of enclosed NVR chassis under continuous load.\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\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Gross Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e0.69\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_HD8000SA_datasheet.pdf\" target=\"_blank\"\u003eProduct Specification Sheet\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eHow many cameras can this drive support?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe WD Purple WD80PURZ supports up to 64 camera streams simultaneously. Actual camera count depends on resolution, frame rate and compression codec — a typical configuration might run 16-32 cameras at 1080p or 8-16 cameras at 4K resolution.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat's the difference between WD Purple and standard desktop drives?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eWD Purple drives are optimised for continuous streaming write operations typical of surveillance systems, with firmware tuned for 24x7 operation and higher annual workload ratings. Desktop drives prioritise random read\/write performance and are not designed for the sustained write loads of multi-camera recording.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow much recording time does 8TB provide?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eRecording time depends on camera resolution, frame rate, compression and motion activity. As a rough guide, 8TB supports 60-90 days of retention for a 16-camera system at 1080p with H.264 compression, or 30-45 days for 4K streams. Systems using H.265 compression extend retention time by 30-50%.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan this be used in a standard desktop PC?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003ePhysically, yes — it uses a standard SATA III interface. However, the drive's firmware is optimised for surveillance workloads (continuous write, streaming video) rather than desktop workloads (random access, application loading). For general desktop use, a WD Blue or WD Black drive would be more appropriate.\u003c\/p\u003e","brand":"ESP","offers":[{"title":"Default Title","offer_id":45294238630155,"sku":"HD8000SA","price":591.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/HD8000SA_76a9b789-3f07-4c25-9b5b-ab22da373a47.jpg?v=1714669900","url":"https:\/\/niori.co.uk\/products\/wd-purple-8tb-surveillance-hard-drive-wd80purz","provider":"Niori","version":"1.0","type":"link"}
