At the Embedded World 2022 conference in Nuremberg, Germany, Micron on Tuesday formally unveiled the “i400,” the first 1.5 terabyte industrial-grade microSD.
The Micron 176-layer 3D NAND technique, which is similar to the technology used in SSDs, is utilized to produce the i400 microSD series, with a focus on durability and performance. As a storage system for video security surveillance, it will primarily serve the enterprise sector.
The i400, according to Micron, is made to last for five years of nonstop, 24-hour high-quality recording and has an MTBF of over two million hours, making it extremely durable (i.e., the card might even surpass the life shelf of the device it is used for).
Additionally, according to Micron, the i400 is capable of “handling up to eight AI events per second, such as object identification and categorization like license plate or facial recognition,” while simultaneously capturing 4K video.
The i400 microSD will be available in 64GB, 256GB, 1TB, and, of course, 1.5TB capacities, which is 50% more storage space than Micron’s previous champion, the C200.
It cost USD 450 compared to SanDisk’s initial 1TB microSD, which was released in 2019. Although Micron has not yet provided information regarding pricing and availability, we may anticipate that the 1.5TB i400 microSD will have a high price point and that locating it will be challenging due to supply chain issues.
