WD Surveillance Hard Drives

WD PurplseWD Purple
Surveillance Storage

WD Purple™ drives have been engineered specifically for surveillance, so they’re able to withstand the elevated heat fluctuations and equipment vibrations within a NVR environments. An average desktop drive is built to run for only short intervals, not the harsh 24/7 always-on environment of a high-definition surveillance system. A disruption to a drive could result in a failure that impacts multiple users, your security archive, or even the entire system. With WD Purple™, you get reliable, surveillance-class storage that’s tested for compatibility in a wide-range of security systems.

Industry-leading storage. Surveillance you can trust. WD is a worldwide leader in the hard drive industry. With WD Purple™ surveillance storage, you have a drive engineered for high temperature, always-on surveillance systems so you can rely on quality video playback when you need it most. Whether you’re protecting loved ones or monitoring your business, WD Purple™ offers performance you can trust.

Wide compatibility. Seamless integration. WD Purple™ hard drives are built with compatibility in mind, so you can quickly and seamlessly add capacity to your surveillance system. With a wide range of industry-leading enclosures and chipsets supported, you’re sure to find the DVR or NVR configuration that’s right for you.

Expand your view to 64. Each WD Purple™ drive is optimized to support up to 64 cameras. With so many options, you have the flexibility to upgrade or expand your security system in the future.


WD Gold
Datacenter Hard Drive

With ten times the workload capacity of desktop drives, WD Gold hard drives feature advanced technology that delivers industry leading reliability, capacity, power efficiency and performance. Designed for a multitude of Datacenter-specific applications, WD Gold hard drives are perfect for high-availability server and storage arrays that demand the most robust storage device available with 24/7 premium customer support.
         
Full range of nearline capacities – From boot servers to high end enterprise storage systems, WD Gold hard drives offer the capacities required for the most demanding datacenter environments.
         
Highest workload capability – Delivering both performance and reliability to any datacenter environment, WD Gold hard drives are designed to handle up to 550TB per year which is the highest workload capability of any 3.5-inch hard drive.
         
Highest level of reliability – With up to 2.5 million hours MTBF, WD Gold hard drives deliver the highest level of reliability and durability for yearly operation (24x7x365) within the most demanding storage environments.
         
Vibration Protection – Enhanced RAFF™ technology includes sophisticated electronics to monitor the drive and correct both linear and rotational vibration in real time. The result is a significant performance improvement in high vibration environments over other desktop hard drives.
         
RAID-specific, time-limited error recovery (TLER) – Prevents drive fallout caused by the extended hard drive error-recovery processes common to desktop drives.
         
Extended thermal burn-in test – Each drive is put through extended burn-in testing with thermal cycling to ensure reliable operation.
         
Dynamic fly height technology – Each read-write head’s fly height is adjusted in real time for optimum reliability.
         
Dual actuator technology – A head positioning system with two actuators that improves positional accuracy over the data track(s). The primary actuator provides coarse displacement using conventional electromagnetic actuator principles. The secondary actuator uses piezoelectric motion to fine tune the head positioning to a higher degree of accuracy.
         
Compatibility testing – All WD Gold hard drives are extensively tested across a variety of popular OEM storage systems, SATA controllers, and host bus adapters, to ensure ease of integration for a plug and play solution.

Premium support – Dedicated 24x7 over the phone support is included with every WD Gold hard drive.
