Hundreds of millions of devices across six continents — from orbit to your pocket.
The Transiting Exoplanet Survey Satellite (TESS) uses YAFFS to store and preserve incoming scientific data in the harsh environment of space. Cosmic rays and radiation cause bit flips in memory — exactly the kind of challenge YAFFS was designed to handle.
TESS monitors over 200,000 stars, identifying planets from Earth-sized worlds to gas giants across a wide range of orbital distances. It's the first spaceborne all-sky transit survey, and YAFFS keeps its data safe millions of miles from the nearest service technician.
YAFFS has been used in aerospace operations since 2016, proving its reliability in one of the most demanding environments imaginable.
Tape Replacement Ltd builds digital data storage solutions that replace outdated magnetic tape and magneto-optical drives in legacy telephone switching systems. Their products save telecoms companies millions in upgrade costs while improving system reliability.
Their storage layer uses two independent stacks of NAND chips in a RAID-1 configuration, with YAFFS managing the flash storage underneath.
"We've been running the units for almost 15 years now, and we have never seen a failure of the underlying YAFFS/NAND storage system. YAFFS provides us with a fast, reliable storage mechanism which is especially useful given the changes in NAND technologies over the years, and the intricate technical details of their behaviour."

Zero storage failures
It wouldn't be surprising if YAFFS hadn't already been part of your day today.
From NASA's TESS satellite to pilot information systems and cabin electronics, YAFFS handles the cosmic ray-induced bit flips and extreme conditions that space and aviation demand.
Internet routers, cell towers, telephone exchanges, and video phones rely on YAFFS. Tape Replacement Ltd uses it to maintain legacy switching systems for major telecoms worldwide.
Android phones were early adopters, creating a massive international test bed. YAFFS also powers cameras, set-top boxes, GPS devices, synthesisers, and coffee makers.
Point-of-sale equipment, building security systems, public information displays, food safety systems, and emergency services infrastructure all trust YAFFS for reliable flash storage.
Laser and GPS-guided construction equipment — graders, pavers, and heavy machinery — use YAFFS for dependable data storage in demanding field conditions.
Professional movie production cameras, studio monitors, TV broadcast equipment, and video codecs rely on YAFFS for fast, reliable flash storage during capture and playback.
