How to avoid end of life from NAND correctable errors (2020)Status: Available Now
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? What other sorts of media management can help get the most lifetime out of your flash media based device?
This talk will cover these sorts of problems and impacts in detail, from flash file systems to SSDs and other NAND flash-based media. While we can't speak to what the firmware in your devices are doing, we have an excellent knowledge of what they should be doing, and also detail the sorts of conversations a system designer should have with their flash media vendors.
