With "only" three drives, you don't want to stripe across them. There are four activities which consume disk resources: i) maintenance of the active and history files ii) maintenance of the overview hierarchy iii) writing out the articles themselves iv) scribbling to /var/log/news Whilst the latter is comparatively "cheap" as it simply extends an existing file (writes deferred by caching), the first three are best spread across separate spindles for the best resultant performance. Striping or concatenation will hurt more than help, michael
