Automotive systems have become increasingly complex, raising the risk of flash memory wear out occurring before end-of-life of the car. What’s more, fragmentation could simply break an automotive system. This whitepaper describes those effects in more detail and suggests ways to mitigate the risks.

Groundbreaking studies have shown fragmentation to be a risk to modern automotive systems, potentially causing sluggish flash storage performance and even critical system failure within a car. This whitepaper examines in detail the ways that fragmentation affects the performance of an automotive system.

Flash media is fabulous for most use cases, but heavy reads can cause correctable errors. Linux flash file systems actually shorten the life of the media when dealing with these errors. How does this change with multiple bits per cell, including recent QLC NAND? This paper, by Thom Denholm, covers both this problem and the impacts in detail, from flash file systems to SSDs and other NAND flash-based media.

Over the years, we have developed considerable expertise and special-purpose tools to help diagnose all kinds of data issues. Our approach is to first determine what’s wrong, then to try to identify the steps it would take to get the system to this state. Is it something that the software could have caused? Did the media fail or is it something different? This paper examines how such questions are answered, and describes file system-related troubleshooting techniques.

Managed NAND media (SD and SSD) has failure modes which are devastating to embedded systems. It is crucial that file systems detect and manage these failures, and this paper outlines methods used by some Linux file systems to do so. It also examines one additional failure mode not handled properly by any open source file system. Learn more by downloading the full whitepaper.

Removing data securely from flash media is more challenging than older magnetic designs. The software and firmware must work in unison to provide secure solutions that are increasingly in demand. In this paper, we detail the secure interface from the application to the media and point out the possible pitfalls along the way. Download the whitepaper to learn more.

When a device fails in the field, consequences can be significant. In our conversations with embedded original equipment manufacturers (OEMs), one thing is certain: addressing a problem in the field is costly. Anticipating and preventing field failures enable market leaders to invest in innovation – rather than costly resource-draining diagnosis, repair, and redesign. Furthermore, as data storage needs of these devices has increased dramatically over the years, unreliable data storage can be a significant contributor to field failures.

Storage hardware that can ensure consistency and correctness in space applications require more than commercial off-the-shelf SD and SSD can deliver. Alternative solutions like Triple Modular Redundancy (TMR) NAND flash have unusual interfaces and requirements. Balancing these two, what best practices and solutions can prevent mission failure and still fit within tight budgets? Read the full whitepaper to learn more.
