The most trusted file system solutions
for USB storage and SD card support

GravityCS by Tuxera™ is our commercial-grade suite of file system software that makes it possible for you to connect any external storage media – like USB sticks and SD memory cards – to any device. Our file system implementations are built on tried and true technologies like NTFS®, FAT™, exFAT®, APFS, and HFS+ – but we’ve added patented optimizations to make data transfers faster, storage access more responsive, and provide fail-safe measures to keep data intact and secure.

Storage software advantages

Multi-media, multi-platform support

Just plug in any external storage media, and it works seamlessly. Our storage software supports USB, SD™, SDHC™, SDXC™, e∙MMC, HDD, and SSD storage media. Plus, it’s compatible with all the major operating systems — Android™, Linux®, Chrome OS™, QNX®, Nucleus®, Windows® Embedded, and more.

Patented, fail-safe file systems

No lost data. Our storage software safely stores data in the event of power failure or unexpected power loss. GravityCS by Tuxera solutions also come with volume check and repair tools to ensure the system heals itself in case of faults. That’s a critical fail-safety measure missing from other industry-standard file system alternatives.

Premium user experience

GravityCS by Tuxera file systems are optimized for the environment they’re 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 favorite apps.

Top storage performance

Open-source storage drivers are good — but they’re typically made for generic use cases. That’s why you may run in to I/O bottlenecks. What makes our solutions different is they’re built for your specific use case on your specific hardware platform. We do all the necessary tuning and testing to get the maximum performance from your storage stack.

Extensive file system tools

We have the best file system tools on the market to help you get the most from your storage over the entire product lifetime. Our package includes tools for formatting, check and repair, debugging, our proprietary benchmark utility, plus a benchmarking guide and documentation for all the tools.

Responsive customer support

The largest team of file systems experts — at your service. We’ve been solving complex storage challenges for our customers for over thirty years. Our engineers are on call to help you through every stage of your product’s lifetime, including full integration support.
