A Robust Flash File System Since 2002

Yaffs (Yet Another Flash File System) is an open-source file system specifically designed to be fast, robust and suitable for embedded use with NAND and NOR Flash. It is widely used with Linux, RTOSs, or no OS at all, in consumer devices, avionics, and critical infrastructure. It is available under GNU Public License, GPL, or on commercial terms from Aleph One.


Yaffs in space!

Tess satelliteThe NASA Transiting Exoplanet Survey Satellite (TESS) is a project which is searching for exoplanets in orbit around the brightest stars in the sky.

TESS uses our Yaffs File System to store incoming data and preserve it, in the rigours of the space environment, before sending it back to Earth.

TESS finds planets by in our solar neighborhood by monitoring 200,000 stars for temporary drops in brightness caused by planetary transits. And recently TESS found its first earth-sized planet!

Some File Systems are not robust enough to be suitable for such exacting work.

NASA has more about details of the current mission objective and the newly approved extended TESS mission and you can find out more on Wikipedia.
