Connected Home Edge + SD & microSD Cards

Improve Revenue with Enhanced Services and Faster Deployment


Enabling Innovation in the Connected Home

Through the advancement of technology and services, the Connected Home and Smart Home are now a reality. Rich content, VOD, cloud DVR, home security, home automation and IoT are essentially data-driven applications and services. NAND Flash plays a key role in the real time distribution, consumption, analytics, management, and security of the data which drives these services.

The SD™ and microSD™ flash memory storage solutions for the connected home are designed to address application-specific use cases (such as pause live TV, home security cameras, data caching, and logging). Western Digital’s home solutions have been designed to assist our customers (end users, OEMs, and service providers) to deliver a superior user experience.
