Has anyone used these?  Do they perform in-place reorganization, or do
they work like dcopy?  The biggest headache with dcopy is the requirement
for a second volume.

I typically reorganize my disks whenever they become more than 25-30%
fragmented.  Usually, I just do a mkfs and restore after a normal
weekly backup.  It's not quite as good as dcopy, but it's close enough,
and still results in a big throughput improvement.
