You might want to rethink that. The sync option is nice because that means that writes are completed immediately to disk. This is nice because it means that if you pull the disk out without umounting it, you are less likely to lose data (unless you do it while an actual data transfer is occurring). Without sync, the write could take an arbitrarily long time to be committed to disk, if there are not enough data to convince the driver to flush the cache.
