Reliable Storage you can count on You need reliability and performance in your security system. This means you need a hard drive that can handle the high workload demands of 24/7 security monitoring. That's why Lorex offers WD Purple surveillance hard drives. These drives are built specifically for continuous security recording and can even continue to record as you stream live or previously recorded video.

Surveillance vs. Traditional Hard Drives Traditional desktop hard drives are not designed to run continuously. Your WD Purple surveillance hard drive, on the other hand, can run optimally 24/7. In fact, the average desktop or laptop hard drive has a workload rate of about 55TB/year. WD Purple Surveillance drives, conversely, have a workload rate of 180TB/year. This higher workload rate greatly increases the reliability of the hard drive, so that there is a much lower risk of hard drive failure or data loss. These drives also have a MTBF (Mean Time Between Failure) of up to 1.5 million hours, which is much longer that the average desktop's hard drive.

WD's exclusive AllFrame™ 4K technology Western Digital's Purple drives feature AllFrame 4K™ Technology. This technology is designed to minimize frame loss to ensure you don't miss a moment. It also improves ATA streaming, helps reduce errors, pixelation, and other video interruptions that can occur with a video recording system.

IntelliSeek™ technology One of the common issues with recorders is noise caused by vibrations. WD Purple drives, however, use IntelliSeek™ technology, which calculates the optimum seek speeds to keep ambient noise and vibrations at a minimum. This not only prolongs the life span of the hard drive but also helps minimize the power consumption of your NVR or DVR.
