The WD Purple 4TB HDD is a surveillance-class internal hard drive engineered for 24\/7 always-on security recording in NVR and DVR systems. Featuring a 3.5-inch form factor with 4TB of storage capacity, 5400 RPM spindle speed, 256MB cache, and a SATA III 6Gb\/s interface, this drive delivers the reliability and performance demanded by high-definition surveillance applications.<\/p>\n

Performance and AllFrame Technology<\/h2>\n

The WD Purple 4TB HDD utilizes WD’s exclusive AllFrame technology, which is specifically designed to reduce frame loss and improve overall video playback in surveillance systems. With a sustained data transfer rate of up to 180 MB\/s and a 256MB cache buffer, the drive handles write-intensive, low bit-rate, high stream-count workloads typical of mainstream surveillance applications. The 5400 RPM class speed balances performance with thermal efficiency for continuous operation.<\/p>\n

Surveillance-Grade Reliability<\/h2>\n

Built to withstand the stresses of 24\/7 recording, the WD Purple 4TB HDD offers a workload rating of up to 180TB per year and 300,000 load\/unload cycles. It is tested for compatibility with a wide range of security systems and is engineered to handle heat, vibration, and continuous write operations. The drive supports up to 64 high-definition cameras, making it scalable for expanding security installations.<\/p>\n

The WD Purple 4TB HDD features a SATA III 6Gb\/s interface, ensuring broad compatibility with modern NVR and DVR systems as well as desktop enclosures. The 3.5-inch form factor fits standard drive bays, and the drive supports up to 16 drive bays in multi-bay surveillance configurations. TLER and ATA streaming support further enhance its suitability for RAID and surveillance environments.<\/p>\n

Design and Form Factor<\/h2>\n

Measuring 5.8 x 4 x 1.03 inches and weighing approximately 1.5 lb, the WD Purple 4TB HDD is designed for standard 3.5-inch internal drive bays. Its surveillance-tuned firmware prioritizes write operations to maximize recording performance, ensuring that critical video footage is captured without interruption. The drive’s robust construction and thermal management make it ideal for enclosed NVR cabinets and security system deployments.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div><\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"
