Flash Friendly File Systems

Posted by: Thom Denholm

Earlier this year I had an opportunity to speak at Embedded World 2014 on the topic of Flash Friendly File Systems. Flash media is growing by leaps and bounds, and the chosen file system is a key component. For this paper, I drew on both my own development and support experience at Datalight and the experience of our staff.

The paper we put together describes the important aspects to be considered before selecting a file system which will treat the flash media in the best possible manner. We looked at both performance and endurance, focusing on the reliability and power use needed by today's embedded designs.

Based on the response from the Embedded World audience, we realized that more depth on this topic would be helpful. Returning from Germany, we edited and updated the paper with the very latest performance data. F2FS is beginning to mature as a product - though not all the tools are yet functional - which allowed us to include it in all of the measurements this time around.

The results of these edits are the paper linked below. If you want to know more about this topic, please feel free to contact me.
