Micron announces sampling of 1.5 terabytes microSD card

At embedded world Micron Technology announced sampling to customers of what is said to be the world’s highest-capacity microSD card, the i400, at an unprecedented density of 1.5 terabytes (TB).

This card is designed for industrial-grade video security with the 176-layer 3DNAND, also pioneered by Micron.

With rising demand for real-time video security, the internet protocol video security and video security-as-a-service (VSaaS) market is estimated to be worth $83 billion by 2030. Fleet dash cameras, smart home security, police body cameras and AI-enabled cameras in factories all need storage capable of handling media-rich data.

As the world’s highest-capacity microSD card, Micron’s i400 is ideally suited for video storage at the edge and hybrid VSaaS deployments.

The substantial 1.5TB density can store up to four months or 120 days of video security media locally, enabling users to optimise what data is stored in the cloud.

The high capacity eliminates the need to continuously upload data to the cloud for primary storage, a process that guzzles network bandwidth and operational expenses.

Small businesses looking to reduce expensive bandwidth or remote sites — such as cargo ships or oil rigs with limited connectivity — can instead periodically upload data to the cloud for backup while relying day to day on i400 storage at the edge.

Bringing primary storage to the edge enables real-time AI analytics and faster decision-making within smart cameras. This speed is especially crucial for critical law enforcement, public health or safety decisions.

Unlike most cards on the market that are consumer-grade and have limited write capability, the i400 is designed for the video security environment with features such as:

  • Five years of high-quality continuous 24x7 recording
  • Ability to concurrently handle 4K video recording and up to eight AI events per second, such as object detection and classification like license plate or facial recognition
  • Two million hours for mean time to failure

Micron is sampling the i400 to customers, including Verkada, a cloud-managed enterprise building-security provider.

“Micron’s industrial-grade storage is key to helping us protect our customers and communities, from schools to large enterprises, by meeting the most demanding of video retention and security requirements,” said Raj Misra, vice president of hardware engineering at Verkada. “The latest i400 solution will provide further peace of mind by enabling greater video storage at the edge and faster in-camera AI analytics — important in crises where response time is paramount.”

 

To better provide its high-performance, ruggedised solutions to the industrial market, Micron is also adding partners to its Industrial Quotient (IQ) partner program.

Additionally, the company is announcing it has received the first International Organization of Standardization (ISO) 26262 Automotive Safety Integrity Level (ASIL) D certification of memory for its low-power double data rate 5 (LPDDR5) DRAM, which is based on its 1-alpha process node.
