That article was the impetus for me to try it out for the first time 
while rebuilding a home micro-server from an old netbook with a 8Gb SSD 
(and broken screen). Turning on compression and running a "defragment" 
brought my Debian install from about 1.8Gb down to under 600Mb, with no 
obvious slow-down. Funny, it was the first time I have ever run a 
defragment on a Linux system! Brings  me back to my Win ME days! lol.

I figured it was a good place to start because at 8Gb, I can easily do 
bare-metal backups in case I run into a fs bug. It has a bit of a 
learning curve, so I'd suggest doing some reading before doing anything 
fancy with it, but it's really exciting.
