I started out feeding quarters to Pong , Breakout and Space Wars in bars during the mid to late 70 ' s LOL . But from then all through the 80 ' s to the early 90 ' s I was busy doing other stuff for entertainment , so I missed a lot of video games some are nostalgic about here . Then , as a nontraditionalaged college student like around 1993 , I discovered playing Marathon multiplayer on the campus network of macintosh computers . Here I am still playing Bungie games <| sep |> Difference is I have a brain and you support trump <| sep |> This is the one . <| sep |> It ' s not any more dangerous than using another filesystem on hardware raid . Regarding caching issues , this is why raid controller batteries and server UPS are important . Plus , there are plenty of other features that zfs provides other than raidz . Obviously it ' s not preferred but I ' ve been in a similar boat converting application servers into files servers with zero budget and a raid controller that doesn ' t support passthrough mode . Setup desired raid on the controller , create a single zfs volume and take advantage of snapshots , ARC , thin provisioning , fslevel compression , etc .
