GravityCS by TuxeraStorage 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.

Protect data integrity

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.
