gmirror, gvinum or ccd to mirror root-filesystem under 6.0R

[Reinhard]

hi list

currently i use gvinum under 5.4-R to mirror (raid-1) my
root-file-system. works nice but was a little bit
complicate/nasty to setup (basically it was the procedure as described
on http://devel.reinikainen.net/docs/how-to/Vinum/#Chapter3.2 )

i plan to install 6.0-R in near future and ask myself if i should use
gmirror, ccd or gvinum (again) for software-raid for mirroring the root
file-system, as to:
- reliability, stability issues
- performance issues
- minimum installation/configuration effort 
- advantages / disadvantages of gmirror vs. ccd vs. gvinum

what are the experiences here ?

thanks for answers,
~reinhard
