InnoDB won't give you much in terms of disk crash recovery. That's what
backups are for.
Where InnoDB does excel is if your database server dies while updating
rows. If that happens, your database will come back up with sane data.
For both table types, once the data has been flushed to disk, the data
will still be there if your db server crashes.
It does indeed sound like you will be better off using MyISAM. This will
also reduce your disk space usage considerably.
