Kioxia has announced the first working prototypes of microSDXC memory cards from 2TB. Storage capacity supported by the standard for years, but not yet used.

Kioxia will use BiCS FLASH 3D memory and self-designed controller to reach truly stratospheric capacity. They will be produced using the company’s own manufacturing technology, which will stack sixteen 1-terabit 3D flash memory dies with a maximum thickness of 0.8 mm in the die assembly area.

The drives will reach a maximum sequential read speed of 104 Mbps under UHS-I and we expect a minimum of 30 Mbps when writing. They are currently in the prototype stage and the company hopes to start mass production in 2023.

2Tbyte microSDXC makes the standard more interesting

Until the launch of SD Express, which will use the PCIe and NVMe protocols (same as SSD), the new Kioxia microSD will be the ones that offer the largest storage capacity in the industry.

It must be said that microSD cards, the smallest variant of the Secure Digital standard for external and removable storage, are a necessary group of products to increase the storage capacity of hundreds of millions of devices, from smartphones to cameras to drones. , tablets, GPS, portable consoles and long etc.

Although the main purpose of this format is still to store data, and in fact there are devices that use it as the only medium, are also used to launch applications and free up the device’s internal storage, as can be done on Android smartphones, to run full-fledged operating systems or as bootable media.

These 2 TB capacities will be useful for all use cases. They will be available in 2023.
