As of now, I'm not familiar with flashbench. But, I suggest you can reference the following survey written by Arnd. https://wiki.linaro.org/WorkingGroups/KernelArchived/Projects/FlashCardSurvey In the table, there are two parameters you need to consider carefully. - Allocation unit : -s section_size, multiple of 2MB segment - # open AUs linear : mount option, -o active_logs=n (one of 2, 4, and 6) BTW, it is very hard to retreive the zone size by the timing attack, but usually I believe the section size is the most critical parameter to the NAND firmware. > Should I also use -e "mp3,mp4,jpg,tiff,mpg,aac,mov,wav,ts,flv,pdf" > because > these types are frequent and never get edited? You can add just "tiff,aac,wav,ts,flv,pdf". Other extensions are already added by default.
