Western Digital (WD) Purple WD30PURX 3TB SATA 6.0Gb/s HDD


WD Purple Surveillance Storage is built for 24/7 always-on surveillance in high-definition security systems that use up to eight hard drives and up to 32 cameras. Exclusive AllFrame™ technology works with ATA streaming to reduce error pixilation and video interruptions that occur when desktop hard drives are incorrectly used as storage in security systems.

Product Description

The right drive for the right job.
WD Purple drives have been engineered specifically for surveillance, so they’re able to withstand the extreme heat fluctuations and equipment vibrations within an DVR environment. 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.

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.

Trust your view with AllFrameMissed frames and lost footage is a serious problem when video surveillance needs to be retrieved. With an ordinary desktop hard drive, errors and video interruptions are common, but not with WD Purple. All WD Purple drives are equipped with AllFrame technology, which improves ATA streaming to reduce frame loss, improve overall video playback, and increase the number of drives supported within a DVR.


  • Engineered specifically for surveillance security systems.
  • Reduced video frame loss.
  • Tuned for write-intensive, low bit-rate, high stream-count applications typical to most surveillance applications.
  • Prioritized write-operations for maximized surveillance performance.
  • TLER & ATA streaming support.
  • Support for up to eight drives.

Less power. More efficient.Low power consumption is a necessity in a high-temperature, always-on surveillance environment. With our exclusive IntelliSeek technology, WD Purple drives are able to calculate optimum seek speeds, keeping power consumption low so ambient noise and vibrations that would damage an ordinary desktop drive are at a minimum.

Three year warrantyAs an industry-leading hard drive manufacturer for over 20 years, WD stands behind their surveillance storage solutions. With a 3-year limited warranty included with every WD Purple drive, you can build a reliable DVR you can trust.
