about?	relocating bad sectors on the disks. Rather than relocate the
	actual sector, a pointer for the sector number is used.
	When a bad sector is found, the pointer updates to skip that
	area - this is done while the drive is reading/writing. If you
	were to watch the performance of this bad sector, as the
	performance appears to increase, it could be said the sector

	In the event of volume corruption, this journal is easy for
	recovery programs to find on the disk and make repairs,
	based on this file. We recommend journaling (if your OS
	supports it), in case of such corruption.
I've heard journaling makes the array run	Journaling only slows down the array by about 2KB/sec. For
slower - should I still use it?	the most part, when a journal entry is written, it is usually only
	a few bytes of data, and doesn't update non-stop. The
	benefits greatly outweigh the small decrease in data rate
