This page gives a short overview of every product covered in this documentation, grouped the same way as the navigation above. Click through to a product to reach its first page.

Embedded file systems​

Fail-safe resilience. Embedded file systems decide whether your device recovers cleanly from a crash or corrupts silently. Ours guarantee predictable recovery, corruption prevention, and flash endurance across every major operating system and bare metal, with compliance readiness built in.

  • Tuxera EdgeFS — The only embedded file system built to protect critical data in resource-constrained environments, with a footprint small enough for certification.
  • Tuxera NitroFS — A transactional file system that protects metadata and user data from corruption through copy-on-write design.
  • Microsoft NTFS by Tuxera — Commercial-grade NTFS implementation with hassle-free read/write access, up to six times faster than open-source options.
  • Microsoft exFAT by Tuxera — Fail-safe, licensed exFAT driver for USB drives and SD cards that exceeds storage limits while securing your data.
  • Microsoft FAT by Tuxera — Universally recognized FAT driver for embedded devices and removable storage, optimized for minimal RAM use.

Flash memory software controllers​

Seamless interoperability. Flash fails in predictable ways: cells wear out, blocks go bad, performance degrades. A software flash controller manages all three, extending device life and cutting total cost of ownership over long deployments.

  • Tuxera FlashFX Tera — A software flash controller with patented wear leveling and Smart Write techniques that prevent early storage failure.

Embedded networking & security​

Secure connectivity. Connect your devices with networking solutions built for the most demanding environments. Our MISRA-compliant TCP/IP stacks and security protocols deliver reliable connectivity with minimal footprint, supporting both IPv4 and IPv6.

Enterprise-grade file sharing​

Enterprise networked storage. Enterprise file sharing under load is about predictable performance at scale: high availability, high throughput, and stable behavior across mixed OS clients in data center environments.

  • Tuxera Fusion SMB — The fastest, award-winning enterprise SMB server — access and transfer huge amounts of data reliably across Linux, macOS, or Windows.
  • Tuxera Fusion NFS — Content coming soon.
