The times for decompression, in particular, that you mention 
were quite impressive. 

It appears, though, from what you say that Diamond is more of 
a compression utility than a true archiver. A true archiver provides 
extensive support for interacting with an archive and would include 
such features as file storage on a wide variety of media including 
tape, quick access to data in the archive via a catalog stored 
on the hard disk, sophisticated file selection, calendared operation, 
and an extensive interface for retrieving files. 

We have been working on these issues for quite some time now 
in Retrospect, our recently released archiving and backup program. 

Having not seen Diamond, I don't know how it fares in these areas.
