Hello experts, I am developing a C165 based mass storage device and need to implement a FAT file system on flash. I've read a lot about problems with the life time of NAND due to repeated read/write of the FAT and ST talk about wear levelling software and journeling which are basically jump tables relating vitual addresses to physical addresses to combat the problem. I know that there are commerical file systems offered by companies and would really like to know if anyone has experience of any of these or selecting NAND for this purpose. All advice and links greatly appreciated, Best regards, Malcom.
