We work with all the top Tier-1 suppliers and car manufacturers to deliver power fail-safe, high-performance storage software for all data-critical systems using automotive flash memory – such as ADAS, DVR, EDR, telematics, instrument cluster, and infotainment.
Benefits of Tuxera automotive data storage & connectivity solutions
Unsurpassed storage reliability
Fail-safety guaranteed, even under intensive data workloads and harsh road conditions. Tuxera’s software employs patented methods to protect data retention and volume integrity, prevent or reduce data loss and corruption, and offer power fail-safety and control over data at risk.
The leader for external media access
Tuxera’s file systems are the leading choice in premium automotive infotainment (IVI) systems, already on the roads in millions of cars. Our GravityCS by Tuxera file systems are already at work bringing industry-standard support for high capacity USB drives, and SDHC and SDXC memory cards. These are typically used for infotainment media files, map data, or drive recorder storage.
Fast, responsive storage performance
Our software offers unbeatable performance in handling intensive data workloads – simultaneous recording, viewing, and uploading multiple data streams. It’s designed for consistently high and stable performance over long periods of time. Active caching, and advanced algorithms and data structures ensure maximum I/O throughput and IOPS, and low CPU use for increased automotive system responsiveness.
Quality assurance
Our custom-engineered tests are an integral part of our development and validation process. These tests ensure fail-safety, performance, and lifetime under realistic workloads. We also have Automotive SPICE® capability, offer products which are MISRA C compliant, and are ready for ISO 26262-6:2011 (per project request).
Maximum memory lifetime
Flash hardware is limited by the number of write cycles. This means reduced memory lifetime – and more warranty-related replacement costs. Our software has advanced wear leveling and intelligent write and erase operations that extend flash memory lifetime. These optimizations reduce flash memory wear, and help you control bill of materials (BOM) costs.
Support from start to finish
Customer support and problem-solving are our company cornerstones. We have a range of support options to suit your project requirements. Our experienced engineers are on call for technical assistance in multiple languages, ready to help you at every step of the way, from project design throughout the lifetime of the vehicle model.
Fast mount and boot time
After power loss or a system crash, the system must recover rapidly to keep the data stream flowing. In these so-called “dirty” situations, our files systems mount faster than other alternatives.
Tuxera storage solutions by automotive domain
ADAS/Autonomous Driving storage and networking
Ensuring road safety and an enjoyable ride, ADAS requires rich data from sensors in the car. The storage hardware and software need to withstand heavy read-write-and-repeat cycles every day. A high-performance, lifetime-protecting storage management software is the smartest choice in ensuring the flash memory hardware lasts the entire lifetime of the vehicle.
File systems, flash management, and networking for ADAS data
- File system for Linux, QNX
- File system for INTEGRITY, RTOSes
- Raw flash manager for Linux, INTEGRITY, RTOSes
- File system for VxWorks
- Comprehensive IPv4/v6 network connectivity: IPsec, MAC sec, TLS
- Certifiable TCP/IPv4 networking stack developed to ISO 26262
Car dashcam and DVR
Every millisecond of video data capture counts. The storage solutions for car dashcams and DVRs need to be high performance, low latency, handle multiple, parallel data streams, and withstand countless write and erase cycles.

- For Linux, ThreadX, other RTOSes
- File system for ThreadX, other RTOSes
Digital cockpit and instrument cluster
Ensuring road safety brings emphasis to the critical nature of the data used and stored for this automotive domain. An added challenge is that these environments are often hyperconverged and virtualized, and the storage should support a shared, centralized infrastructure to save on cost and vehicle weight. The storage solutions used in this domain must support these virtualized environments, withstand heavy reads and write-and-erase cycles every day, be power fail-safe, and boot rapidly in case of failure.

EDR: in-vehicle event recorders or black boxes
With the data collected from black boxes, safety analysts and accident investigators can evaluate how cars perform in crashes and ultimately design safer cars. Its main requirement is ultimate durability in order to preserve data integrity. The type of data collected by the EDR depends on regional government regulations and the level of automation of the vehicle.
Vehicle speed, braking, engine RPM, location, radar, LIDAR, and video streams from various cameras are just a few examples of the event data possibly stored inside EDRs.
EDR storage needs to withstand heavy write and erase cycles throughout its lifetime, plus provide rock-solid power-fail safety to ensure data is stored in event of a crash or failure. High-performance, lifetime-protecting, fail-safe storage management software is the smartest choice for black box use.

Connected car IVI and infotainment systems
Tuxera’s file systems are the go-to choice in premium automotive infotainment (IVI) systems. Our GravityCS by Tuxera file systems – Microsoft exFAT by Tuxera, Microsoft FAT by Tuxera, Microsoft NTFS by Tuxera, Tuxera HFS+, and Tuxera APFS – are already at work bringing full interoperability with memory cards and USB storage. They also make IVI systems faster, more responsive, and more durable – helping you deliver the best possible ride to your drivers.
The IVIs of the future need more than just external storage support, however. Future IVIs must be able to run multiple, data-intensive applications at once. An added challenge is that these environments are often hyperconverged and virtualized, and the storage should support a shared, centralized infrastructure to save on cost and vehicle weight. The storage solutions used in this domain may need to support these virtualized environments, while also withstand multiple reads and countless small writes every day, provide interoperability with external storage, and boot rapidly in case of failure.

Automotive telematics
Telematic devices deliver data such as position and onboard diagnostics, fuel consumption, or driver behaviour. The goal is often to improve fleet management and efficiency, and to protect the safety and wellbeing of fleet drivers. These devices require rich data from sensors in and outside the car.
Edge storage needs to be provided inside the car because it’s not feasible to transmit all data to the cloud for further processing. These storage solutions need to withstand heavy read workloads, countless write-and-erase cycles every day, and get the maximum life out of the storage hardware. The storage also needs to be power-failsafe to ensure the necessary data is preserved in event of failure.
