WebFatFs does not run efficiently on NAND without flash translation layer. Because of the large size of erase sector (128KB is very common these days), a naive port of FatFs on NAND will wear out the first sector (frequent FAT updates) and run dramatically slow (when individual 512 bytes sector are updated by copying a whole 128KB erase block).
