Micron’s new i400 microSD memory card offers 1.5TB of storage capacity through the use of 176-layer 3D NAND flash memory, with three data bits per cell.

With the arrival of 3D NAND flash memory, which uses several layers of transistors, manufacturers have explained that the storage of SSDs and memory cards will steadily increase. The new microSD memory card just announced by Micron is proof of this with an increase from 1 TB to 1.5 TB, which represents a new record for this type of support.

However, do not look for the i400 memory card at your favorite retailer, you will not find it! Indeed, Micron intends it for a very specific professional market: that of video surveillance. Currently, the manufacturer is sampling the i400 card to its customers, including Verkada, a provider of security services for corporate buildings.

Thus, the card is more robust in terms of writing than consumer models. According to the manufacturer, it is guaranteed for five years of continuous high-quality recording, 24 hours a day, 7 days a week. It supports an average of two million hours of recording before a possible failure. It can simultaneously handle 4K video recording and up to eight events per second, such as detection and recognition of faces or license plates. Its capacity allows it to store approximately four months of video locally, which makes it possible to optimize data processing, such as analysis by artificial intelligence, by freeing itself from the cloud. However, the manufacturer does not provide information on the read and write speeds of the microSD card.

To achieve this capacity, Micron uses its fifth generation of 3D NAND flash memory, which has 176 layers, with 12 blocks of 128 GB.

This TLC memory (three bits of data per cell) is also used in the latest Crucial SSDs. Thus, the manufacturer went from 32 layers to 64 layers, then to 96 and 128 layers. And it’s not over, since Micron plans to produce a 232-layer flash memory for next year.

The i400 memory card undoubtedly foreshadows 1.5 TB consumer models, but we do not yet know their marketing date. Currently, you can buy a 1TB microSD card, for example the Extreme Pro from SanDisk, for around 200 euros. But still it is necessary that the users need such capacities. If the need exists for storing photos and videos, memory cards are slower than the internal memory of smartphones and sometimes do not have the necessary speed. These considerations explain, for example, the absence of a microSD slot in Samsung’s latest Galaxy S22s. And on the side of Apple, we remain deeply resistant to microSD cards for the iPhone.

It is therefore possible that manufacturers of microSD cards reserve their very high capacity models for specific uses where speed and price are not a constraint.

Micron fits 1.5TB on a microSD

Micron increases the storage capacity of its microSD cards to 1.5 TB, a record for these media the size of a stamp. This card completes a range that has so far ranged from 256 GB to 1 TB.

Do not hope to slip it into a consumer device, this solution is now intended for industrial applications. Micron cites for example the automotive market where electronics need to store huge volumes of data permanently, or that of surveillance cameras for businesses and factories.

Its card can handle a 4K video stream while allowing software to launch up to 8 intelligent image analysis operations at the same time. In terms of reliability, it is said to be able to withstand continuous HD video recording, 24/7 for 5 years. Its price, which is supposed to be stratospheric, has not been communicated.

A 1.5 TB Micro SD card from Micron, especially for video surveillance

With the growing 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. smart home security, police body cameras, and artificial intelligence cameras in factories all need storage capable of handling media-rich data. As the world’s highest capacity microSD card, Micron’s i400 is perfectly suited for video storage and hybrid VSaaS deployments.

The high density of 1.5 TB allows up to four months or 120 days of video security media to be stored locally, allowing users to optimize data stored in the cloud. The large capacity reduces the need to continually upload data to the cloud for primary storage, a process that consumes network bandwidth and operational expense. Small businesses looking to reduce expensive bandwidth or remote sites – such as cargo ships or oil rigs with limited connectivity – can periodically upload data to the cloud for backup, while resting everyday on i400 storage Bringing primary storage to the edge enables real-time AI analysis and faster decision-making within smart cameras. This speed is especially crucial for law enforcement, public health or security decisions. Unlike most cards on the market which are consumer grade and have limited write capability, the i400 is designed specifically for video security:

  • – Five years of continuous, high-quality, 24/7 recording;
  • – Ability to simultaneously handle 4K video recording and up to eight AI events per second, such as object detection and classification such as license plate or face recognition;
  • – Two million hours for the mean time to failure.

Micron i400: The world’s first 1.5 TB SD card!

Micron now offers customers the world’s highest capacity microSD card, the i400, with an unprecedented density of 1.5 terabytes (TB). It has just been presented at the show Embedded World in Germany. This card is designed for video file security with the world’s first 176-layer 3D NAND, also developed by Micron. To provide its high performance solutions to the industrial market and professionals who have substantial needs.

With the new generation of driver assistance systems (ADAS) wanting demanding levels autonomy and of security, this certification validates that the LPDDR5 from Micron meets stringent functional safety standards and positions it to enable innovations that will unlock the full potential of tomorrow’s vehicles.

“With edge devices generating critical information for everything from public safety to vehicle autonomy to manufacturing operations, today’s smart applications can’t afford to compromise on latency or quality,” said Kris Baxter, vice president and general manager of Micron’s Embedded Business Unit. “Micron’s newest high-performance solutions – our i400 microSD card for video security and the ASIL D-qualified LPDDR5 for automotive – will enable businesses to perform better and drive innovation. »

The first card 1.5TB microSD in the world offers fast and large storage for AI-enhanced video file security, so it’s a breakthrough in the middle of storage devices.

The massive 1.5TB size allows up to four months or 120 days of security video and photo to be stored locally, maximizing the data stored in the cloud. The large capacity reduces the need to continually upload data to a cloud for storage.

Unlike most cards Consumer SDthe i400 is designed specifically for video security:

  • Five years of continuous, high-quality, 24/7 recording;
  • Ability to simultaneously handle 4K video recording and up to eight AI events per second, such as object detection and classification such as

The SD card incorporates super fast low latency memory below the standard LPDDR5. It offers excellent speeds and much better reliability, which is why it is used in the automotive world with ADAS systems that allow smarter cars thanks to AI which open new doors to this expanding field.
