+    Note that the behavior of the "rwd" flags is platform and hardware specific
     and might not provide the same level of guarantees as FileChannel#force.
     For example, the write will skip the disk-cache on SAS and SCSI devices
     while it might not on SATA devices. This is an expert level setting,
