Micron introduced the 1.5 TB card, which it claims is the world’s largest capacity microSD card. Capacities in the i400 series microSD card family will be available in 64GB, 128GB, 256GB, 512GB, 1TB and massive 1.5TB. The cards are designed for edge storage applications focused on continuous video recording or handling tasks with multiple simultaneous AI processes.
All i400 boards are rated for up to five continuous years of 24/7 operation with a mean time between failures (MTBF) of two million hours. They can also work in environments between -25 degrees Celsius and 85 degrees Celsius, and they also provide protection against damage from water, magnets, X-rays, impact and shock.
The i400 series uses Micron’s 176-layer 3D NAND introduced in late 2020. At the time, the company said the number of layers was about 40 percent higher than its closest competitor, making it ideal for small form factor solutions.
Micron said the cards will facilitate data storage at the edge. It can also help small businesses reduce the need to constantly upload data to the cloud, which can be costly, especially from remote locations such as cargo ships or oil rigs.
Micron’s new i400 series microSD cards are now sent to customers as samples.
