New Surveillance microSD Card Has High Capacity, and Longevity for Longer Continuous High Bit Rate Recording, Plus Card Health Monitoring Capability and Wide Temperature Resilience

SAN JOSE, CA and Las Vegas (ISC West, Booth #22067) – April 10, 2019 – Western Digital Corp. (NASDAQ: WDC) today unveiled the new Western Digital® WD Purple® SC QD312 Extreme Endurance microSD™ card for designers and manufacturers of AI-enabled security cameras, smart video surveillance and advanced edge devices that capture and store video at higher bit rates than mainstream cameras. 

According to IHS Markit, global shipments of professional video surveillance cameras are expected to grow from 127 million to over 200 million between 2017 and 2022, and those with on-board storage are expected to grow by an average of approximately 19 percent per year[1].

With the migration to 4K and higher video resolutions, and the introduction of more smart cameras with built-in AI and improved local processing capabilities, surveillance cameras need to be able to store both video and raw data to facilitate these AI capabilities. As a result, storage with higher capacity, more intelligence and greater durability is increasingly required.

Expanding upon four generations of world-class industrial storage products, the Western Digital WD Purple SC QD312 Extreme Endurance microSD card addresses the tremendous growth of high-resolution security video with its rich feature set. The small form factor storage solution was created to meet the demands of extreme endurance, high capacity and challenging environments for the edge storage to confidently store high-quality video while reducing the need for frequent replacements.  

“The complex storage requirements of the growing security camera market are set to push the status quo with modern advanced edge and smart video devices.  Surveillance customers look to durable and reliable devices with intelligent monitoring to save time and investments, said Oded Sagee, senior director, Devices, Western Digital. "With the microSD card introduced today, we are leveraging the power of 3D NAND to ensure no-compromise, primary, on-camera storage for high bit-rate video and advanced functionality for some of the latest AI-enabled smart cameras.”


Western Digital offers a broad portfolio of surveillance storage products and solutions to help people capture, preserve, access and transform their content. Western Digital will be showcasing the new products as well as its entire surveillance portfolio, including the WD Purple 12TB HDD at ISC West (Booth #22067) in Las Vegas. Western Digital is currently sampling the WD Purple SC QD312 Extreme Endurance microSD card to OEMs. For more information, visit our website: Western Digital
