No, not only for them. The frequent access exists for all drives and
will destroy a high-end SCSI disk just as well, but maybe not as fast.

Ehh, how about those using XFS on file servers that have to have an uptime
of hundreds of days ? Changing its place online would be bliss...
However, placing the journal seems to raise the problem: where ? As it's
accessed often, it should be on the area of the disk where speed is
maximum (speed = read+write+seek). But if it's moved, can the new location
be controlled somehow so that it doesn't accidentally end up in an area
with low speed ? Of course, that does mean that free space has to exist at
the new location. That begs the question: could defragmentation or
something similar take care of creating free space at a specific location
on disk ?
