┬┐Why so?

FAT32 is almost the same thing as FAT16, but with different sizes for some
tables and data (metadata). You still need to update the fat area after
writing any new file or modifying its size, so yes, write operations
concentrate on that region of memory. Whether that stresses the device or
cause premature ageing, I can't say.
