Desktop drives are designed for short, intermittent read\/write sessions — not continuous 24\/7 writing from multiple cameras. Under surveillance workloads, desktop drives typically fail much earlier due to heat buildup, vibration stress from adjacent drives in multi-bay enclosures, and workload rates that far exceed their design specifications. The WD Purple is purpose-built and rated for 180 TB\/year of continuous write activity — the WD11PURZ also carries a 3-year warranty that covers this use case, which standard desktop drive warranties typically do not.\u003c\/p\u003e\n\u003c\/details\u003e\n \n\u003cdetails style=\"border-bottom:1px solid #e2e0da;padding:12px 0;\"\u003e\n  \u003csummary style=\"font-size:14.5px;font-weight:500;color:#1a1a2e;cursor:pointer;list-style:none;\"\u003eHow many days of footage will 1TB store?\u003c\/summary\u003e\n  \u003cp style=\"margin-top:10px;font-size:14px;color:#3d3d5c;\"\u003eRecording duration depends on the number of cameras, video resolution, frame rate, and compression format used by your DVR or NVR. As a general estimate: a single 1080p HD camera recording continuously at standard H.264 compression uses approximately 10–15 GB per day. At that rate, 1TB provides roughly 65–100 days of footage from one camera. With multiple cameras, storage is divided proportionally — four cameras would reduce retention to approximately 16–25 days. Most modern NVRs display estimated recording time based on your camera count and settings. For longer retention or more cameras, higher-capacity WD Purple drives are also available at ITFactory.ca.\u003c\/p\u003e\n\u003c\/details\u003e\n \n\u003cdetails style=\"border-bottom:1px solid #e2e0da;padding:12px 0;\"\u003e\n  \u003csummary style=\"font-size:14.5px;font-weight:500;color:#1a1a2e;cursor:pointer;list-style:none;\"\u003eIs the WD Purple compatible with Hikvision and Dahua NVRs?\u003c\/summary\u003e\n  \u003cp style=\"margin-top:10px;font-size:14px;color:#3d3d5c;\"\u003eYes. WD Purple drives are tested for compatibility with a wide range of DVR and NVR systems from major security brands including Hikvision and Dahua. The WD11PURZ uses a standard SATA 6 Gb\/s interface, which is universally compatible with virtually all DVR and NVR enclosures without any adapters or special configuration.\u003c\/p\u003e\n\u003c\/details\u003e\n \n\u003cdetails style=\"border-bottom:1px solid #e2e0da;padding:12px 0;\"\u003e\n  \u003csummary style=\"font-size:14.5px;font-weight:500;color:#1a1a2e;cursor:pointer;list-style:none;\"\u003eWhat is AllFrame technology?\u003c\/summary\u003e\n  \u003cp style=\"margin-top:10px;font-size:14px;color:#3d3d5c;\"\u003eAllFrame is WD's proprietary technology that enhances ATA streaming in surveillance drives. It reduces the occurrence of video frame drops during continuous write workloads — meaning your recorded footage has fewer gaps, glitches, or corrupted segments when compared to standard drives used in the same environment. This is particularly important for incident review, where missing frames can affect the usefulness of recorded footage.\u003c\/p\u003e\n\u003c\/details\u003e\n \n\u003cdetails style=\"border-bottom:1px solid #e2e0da;padding:12px 0;\"\u003e\n  \u003csummary style=\"font-size:14.5px;font-weight:500;color:#1a1a2e;cursor:pointer;list-style:none;\"\u003eWhat is the difference between WD Purple and WD Purple Pro?\u003c\/summary\u003e\n  \u003cp style=\"margin-top:10px;font-size:14px;color:#3d3d5c;\"\u003eWD Purple is designed for mainstream surveillance with up to 64 cameras and a 180 TB\/year workload rating — suitable for most home and small business security systems. WD Purple Pro is built for larger, more demanding installations with 32 to 64 channel NVR systems, AI-enabled cameras, and 4K recording. The Pro model carries a 550 TB\/year workload rating and is rated for up to 32 drive bays. If you are running a large commercial system with AI video analytics or high-channel-count recording, the Pro is the appropriate choice.\u003c\/p\u003e\n\u003c\/details\u003e\n \n\u003c!-- End ITFactory.ca product description --\u003e","brand":"Western Digital","offers":[{"title":"Default Title","offer_id":51926173024388,"sku":"WD11PURZ","price":239.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0370\/5857\/6516\/files\/1718705767_1365796.jpg?v=1780691085","url":"https:\/\/itfactory.ca\/products\/western-digital-12tb-7200-rpm-purple-pro-surveillance-3-5-nas-internal-hard-disk-drive-copy","provider":"ITFactory.ca","version":"1.0","type":"link"}
