Watch out for sector lifetime when using DOSFS. The FAT normally goes to
the same sector, so if you change files a lot (extend, add, delete, etc.)
you can change the FAT so many times that it wears out. Usually only a
problem if you have files into the thousands, but something to consider.
Typical write lifespan of Flash would be on the order of 100 000, but the
FAT could be updated multiple times for each file. One person reported
problems with flash disk failure after copying on the order of 25 000
files when using FAT file system.
