Well, you could do it for any journaled system (XFS, JFS, ext3, reiserfs).

But yes, it seems specifically designed for a battery backed journal. Though the article reviews it for very different purposes.

Though it was a Windows review, and I don't know of any way to make NTFS use a separate device for a journal. (Though I expect it is possible somehow).


The real differentiator is the battery backup part.  Otherwise, the
filesystem caching is more effective, so put the RAM on the motherboard.
