What do you mean ? Micheal has a great <| sep |> thanks a lot for the PM <| sep |> Dude , no idea why this is not getting more love . Some of the line work could use some cleaning up but I am loving the premise . In fact I ' m about to hit you on the DM <| sep |> Now I know why . <| sep |> Not the op , but a important thing to note . RAID IS NOT A backup . That said , having a hot spare configure is standard operating procedure for me , gives the array a fighting chance . I ' m more of a fan of raid 60 , although raid 10 is decent . Raid 0 , 1 and 5 don ' t have a place in a business , as one drive failure can cause a cascade failure . For mission critical things , I have two arrays in raid 60 mirroring each other . That way , I can loose a few drives or a entire array and still maintain connectivity .
