IMHO you shouldn't use RAID. And surely you want to exclude the system drive from the RAID array. At least the system will not go belly up at the moment you have to repair the array...
RAID 1 is mirroring, it is safe but requires an even number of drives in the array and uses 50% capacity for replication. Eg 4 x 1TB drives => 2TB capacity. RAID 0 is just chaining drives with no replication at all. It is totally unsafe. Failure of the weakest drive will destroy all your data. RAID 0 is fast, but you don't need that for SBS. As for the difference in capacity between what's on the label and what the system reports, you are being misled by the (not so) subtle difference between terabyte and tebibyte (also known as terabyte ). See http://en.wikipedia.org/wiki/Terabyte#Usage A 1TB drive will indeed format to around 870 TiB once you've changed unit and accounted for extra space used by the filesystem itself. Surprising, but normal, and happens on about any OS. Also, I suppose the RAID utility reports "no free space" because all drives are already formatted. RAID acts at device level: first create the array, then format the array as if it were a real drive. Creating an array destroys any data present on the drive members. -- epoch1970 Daily dose delivered by: 3 SB Classic, 1 SB Boom iPeng (iPhone + iPad) Squeezebox Server 7.6 (Debian 5.0) with plugins: MusicIP Server Power Control by Gordon Harris WeatherTime by Martin Rehfeld IRBlaster by Gwendesign (Felix) Find cover art by bpa BBC iPlayer, SwitchPlayer by Triode PowerSave by Jason Holtzapple TrackStat, Song Info, Song Lyrics by Erland Isaksson SaverSwitcher, ContextMenu by Peter Watkins. ------------------------------------------------------------------------ epoch1970's Profile: http://forums.slimdevices.com/member.php?userid=16711 View this thread: http://forums.slimdevices.com/showthread.php?t=89910
