Uncompromising Storage with a WD Purple Surveillance Hard Drive
WD Purple drives are engineered specifically for surveillance to help withstand the elevated heat fluctuations and equipment vibrations within 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. With WD Purple, you get reliable, surveillance-class storage that’s tested for compatibility in a wide range of security systems, and some of our latest models (WD22PURZ, WD42PURZ, and WD63PURZ) have improved power efficiency. Exclusive AllFrame™ technology helps reduce frame loss and improve overall video playback.

Western Digital's Exclusive AllFrame Technology
All WD Purple drives are equipped with AllFrame technology, which improves ATA streaming to help reduce frame loss and improve overall video playback, within a multitude of security video solutions.

Enhanced Workload Ratings
WD Purple™ drives feature a workload rating of up to 180TB/year2 - up to three times that of desktop drives - to handle the unique demands of mainstream video surveillance DVR and NVR systems.

Multiple Cameras, Multiple Streams
Modern recorders now support multiple video streams per camera. WD Purple drives support up to 64 single-stream HD cameras (6TB1 and above), and can also support many of the latest cameras that transmit multiple streams to enable basic AI functionality. With so many options, you have the flexibility to upgrade or expand your security applications in the future.

Designed for Today's and Tomorrow's Surveillance Solutions
With an MTBF of up to 1 million hours3, WD Purple drives are engineered for mainstream surveillance DVRs and NVRs that operate 24/7. With tarnish-resistant components3 and support for more than eight bays4, WD Purple drives deliver reliable operation even in harsh environments.

Proactive Storage Management with WDDA
Western Digital Device Analytics™ (WDDA) provides a wealth of storage device parametric operational and diagnostic data to the system; algorithms interpret the data and direct the system to alert system administrators of specific recommended actions to address potential issues. WDDA is intended to empower OEMs, system integrators, and IT professionals to better monitor and proactively manage supported storage devices to maintain optimal operation.

Three-Year Limited Warranty
As an industry-leading hard drive manufacturer, Western Digital stands behind their surveillance storage solutions with a 3-year limited warranty included with every WD Purple drive.

WD WDS500G2B0A 500GB Blue 3D NAND SATA SSD

A New Dimension of Storage
Ready for your high performance computing needs, a WD Blueï¿½ 3D NAND SATA SSD offers high capacity, enhanced reliability, and blazing speed.

High capacity with enhanced reliability
A WD Blue 3D NAND SATA SSD uses 3D NAND technology not only for higher capacities (up to 2TB) than the previous generation WD Blue SSDs, but also to help reduce cell-to-cell interference for enhanced reliability.

Enhanced power efficiency
Offering improved endurance, a WD Blue 3D NAND SATA SSD features an active power draw up to 25% lower2 than previous generations of WD Blue SSDs. And with less power used, youï¿½re able to work longer before recharging your laptop.

Superior performance for high-end computing
For high-end computing applications like gaming, HD media playback, or creative software, look to WD Blue 3D NAND SATA SSDs. 3D NAND technology helps enable sequential read speeds up to 560MB/s and sequential write speeds up to 530MB/s for fast system boot-ups, quick application responses, and rapid transfer speeds3.

Leading-edge reliability
An SSD is designed with no moving parts to help protect against data loss if it is accidentally bumped or dropped. And with 1.75M hours MTTF (mean time to failure)4, up to 500 TBW (terabytes written)5, and several error correction technologies, WD Blue 3D NAND SATA SSDs can help guard data for years to come.

Broad compatibility
With a certification from the WD Functional Integrity Testing Lab (F.I.T. Labï¿½), every WD Blue 3D NAND SATA SSD is verified for compatibility with a wide range of desktop and laptop computers. Every WD Blue 3D NAND SATA SSD goes through extensive compatibility and reliability testing to ensure it meets the high standards of the WD brand.

Downloadable WD SSD Dashboard and Acronis software
Monitor your driveï¿½s available capacity, operating temperatures, SMART attributes and more with the WD SSD Dashboard. Acronisï¿½ True Imageï¿½ WD Edition software, available as a free download, can clone drives and backup your operating system, applications, settings and all of your data.

3-year limited warranty
Every WD Blue 3D NAND SATA SSD comes with a 3-year limited warranty, so you can be confident of your storage when you upgrade or replace any of your drives.
