Maximum data transfer speeds

With Microsoft exFAT by Tuxera, you get the maximum I/O throughput out of any device. Plus, our software reliably handles simultaneous recording, viewing, and uploading of several ultra-HD streams – even in embedded environments with limited resources.

Portable to any environment

Tuxera’s exFAT file system implementation runs seamlessly on a wide variety of operating systems like Linux and Android, real-time operating systems, and even on embedded devices without an RTOS. Our exFAT solution is designed with portability in mind – it runs in embedded microcontrollers with limited system resources with as low as 16 KB of RAM.

Our storage software is optimized for the environment it’s embedded in. That means device users get a premium experience with reliable data storage, longer memory card lifetime, improved responsiveness when accessing stored content, and more available CPU to run their favourite apps.
