Announcement of Development for microSD Express Memory Cards

Nextorage Co., Ltd. (President: Katsuyuki Honda, Kawasaki City, Kanagawa, Japan) is excited to announce the commencement of development for microSD memory cards adhering to the microSD Express standard.

In response to the growing need for compact, high-speed memory solutions in fields such as edge AI, high-quality digital imaging, next-generation gaming, and advanced industrial applications, we are developing microSD Express-compatible microSD memory cards, aiming for a market launch in fall 2024.

The newly developed microSD Express memory cards will adopt the SD Express 7.1 standard, featuring a PCIe 3.0 interface, and will support transfer speeds of up to 985 MB/s as per the standard.
Nextorage has a track record of developing numerous memory solutions utilizing the PCIe interface standard, including M.2 SSDs and CFexpress memory cards, and has received high praise for speed and stability. We aim to leverage this expertise to develop high-speed, stable microSD Express memory cards.
