Presuming a formatted file system... mmap (and periodic msync to force
memory to device -- how much "loss" can you absorb on a restart?) should be
somewhat simpler than regular file I/O operations. The mmap'd file will be
addressed as RAM storage -- so you can readily update single values in the
"array" of memory. File I/O requires tedious seek and write operations.
