Western Digital Corp. has expanded its portfolio of data storage devices purpose-built for the modern surveillance market, introducing three new offerings: the industry’s first industrial-grade 3D NAND UFS embedded flash drive (EFD) for surveillance; an expanded WD Purple microSD card series to support up to 256GB2 capacity; and Western Digital Device Analytics, the new device analytics technology enabling OEMs and system integrators to proactively manage their storage subsystems and maintain optimal operation.
The new devices and tools address the complex and dynamic data demands of a surveillance market in transformation, supporting the high performance, capacity and endurance required by networked and artificial intelligence (AI)-enabled camera systems, as well as other smart video devices operating at the edge.
In modern video surveillance, video and its rich metadata provide valuable insights for use in both forensic analyses and predictive actions, ranging from consumer behavior in retail environments, traffic patterns in cities or crowd control in public environments. Whether in an NVR, IoT gateway, multi-access edge computing node (MEC) or other configurations, surveillance cameras and edge systems are key elements of real-time, AI-enabled systems, driving increased demand for more reliable and advanced storage solutions that can operate efficiently in rugged, 24/7 environments.
3D NAND UFS-based EFD for surveillance
Built on the company’s advanced 3D NAND architecture, the Western Digital iNAND IX EU312 UFS EFD brings UFS speeds combined with industrial grade high endurance and high capacities to cameras and smart video applications at the edge. The new device delivers read speeds of up to 750 MB/s1 and write speeds of up to 320 MB/s1, which support read- and write-intensive use cases, including AI-enabled video cameras and edge devices. Support for up to 768 TBW provides the robust endurance levels required for the continuous recording conditions. The EFD features advanced NAND flash management firmware, including robust error correction code (ECC), read refresh, wear-leveling and bad block management.
Expanded surveillance-Class Storage for 4K- and AI-Enabled Video at the Edge
In April 2018, Western Digital introduced the WD Purple microSD card designed specifically for surveillance cameras, bringing the WD Purple series’ high performance, endurance and reliability to always-on video surveillance cameras at the edge. Now leveraging 3D NAND technology and available in capacities ranging up to 256GB2 with support for up to 1,000 P/E cycles, the WD Purple microSD card line delivers long-lasting, on-camera storage for the demanding 24/7 continuous operation workloads required by AI-enabled and high-resolution professional surveillance cameras. The microSD card supports operating temperatures ranging from -25°C to 85°C and is humidity resistant to support continuous operation in extreme weather conditions and a variety of indoor and outdoor environments.
Supported by Western Digital’s WD Purple hard drive, WD Purple microSD cards, and the Western Digital IX EU312 UFS EFD, the device analytics technology provides system integrators and end users unprecedented ability to proactively manage storage on their surveillance systems. Device analytics provide a set of parametric operational and environmental data to the host system that ultimately helps users pre-empt potential issues. Through its deep analytics capability, device analytics can extract insights and provide integrators and users with recommended actions that will allow improved monitoring and proactive management of their systems to help maintain optimal storage operation, and in turn contribute to reduced total cost of ownership (TCO).
The new Western Digital iNAND UFS EFD, high capacity WD Purple microSD cards and Western Digital Device Analytics technology together complement a full portfolio of data storage devices for today’s surveillance needs. The portfolio includes the Western Digital WD Purple Surveillance HDD for high-capacity support for NVRs and DVRs, the Ultrastar HDD series for use in back-end storage, video analytics servers, and deep learning systems, and the company’s industrial grade iNAND e.MMC, SD and microSD storage solutions for use with surveillance cameras and a variety of connected surveillance applications. Together, they provide OEMs, surveillance system integrators and installers a complete edge-to-cloud solution to capture, preserve, access and transform data.
