WD Purple Surveillance Storage offers exclusive AllFrame technology to bring you premium reliability and peace-of-mind when installing your home or small to medium business security system. WD Purple's exclusive firmware upgrades work with ATA streaming to reduce error pixilation and video interruptions that occur when desktop hard drives are incorrectly used as storage in security systems. WD Purple Surveillance Storage is built for 24/7, always-on, high-definition surveillance security systems that use up to eight hard drives and up to 32 cameras.

You wouldn't use a bicycle to transport cargo across the country because it's not the right tool for the job. You also shouldn't use a desktop hard drive in your surveillance security system because it wasn't designed for that application. WD Purple surveillance-class storage has been tested to be compatible in a wide-range of security systems. These drives are designed to replace standard desktop drives that were not designed for the harsh 24/7 always-on, high-definition surveillance environment. Desktop drives are built to run for only short intervals and are not engineered to withstand high-temperature fluctuations and equipment vibrations found in a typical surveillance application.

Product Reviews
Rated 4.8 out of 5 by 4reviewers.
Rated 5 out of 5 by Expensive, but worth the investment We purchase these for surveillance purposes across our network. They've given us no problems at all, extremely unlikely these will ever fail on us. That said, we find them to be pretty expensive even though they do provide lots of space. I guess we will just have to be patient as space increases and price decreases. December 21, 2015
Rated 4 out of 5 by No problems so far. Same as OEM recorders use. These are identical to the drives factory-installed in the Hikvision CCTV recorders we sell. We have bought a few dozen of these over the last year to expand recording capacity as customers need, and all have worked perfectly without a single failure yet.As an aside, CDW always packages their drives well to protect from damage during shipping. I stopped buying drives from another online store (the "egg" one) years ago because I would regularly receive drives with little or no protection from contact and mechanical shock in the shipping carton, but I have long been happy with CDW.

Rated 5 out of 5 by The 4TB model is great when you are needing space. I usually put them in a RAID 10 configuration to get even greater space. They can take the increase writing that a NVR can do. I have these running in different camera Systems and they just work great. June 17, 2015
Rated 5 out of 5 by DVR Installation I use these drives as hot swappable drivers forr our companies DVR system. They have been flawless in the last three (3) years of use. November 5, 2014
