Micron Launches World’s First 1TB Industrial-Grade microSD Card

Video surveillance cameras and other industrial applications increasingly require real-time responsiveness, ultra-stable performance and high levels of endurance at the edge. We’re addressing this need with the new Micron® i300 — the industry’s highest-capacity industrial-grade 1TB microSD card.

Based on our 96-layer 3D quad-level cell NAND, the Micron i300 delivers surveillance-grade performance for capturing stable, high-quality video 24/7. The i300 card enables users to reliably store more than three months of high-quality video footage right in the camera.

This kind of high-density edge storage enables video surveillance as a service (VSaaS), which continues to integrate more artificial intelligence-based and higher-resolution cameras. It also reduces IT management overhead and system costs by eliminating the need for on-premise network video recorders/digital video recorders, and lowers data transmission costs for VSaaS installations.



  • High Endurance: Support for 3 years of high-quality, continuous 24/7 video recording. 
  • Outstanding Performance: Optimized firmware provides stable performance for 24x7 high-quality video recording with minimal frame drops. 
  • Industrial Quality: Reliable, high quality with 2 million hours mean time to failure (MTTF) or an annualized failure rate of 0.44%.; 2X the reliability of surveillance HDDs used in NVRs today.
  • Smart Tool for Health Monitoring: Health monitoring feature for IP camera integration reports card usage and lifetime remaining and can be integrated into system software to alert end users.
