I don't want a raid 5, which it seems to want to do.

By default you'd end up with a 4x3TB RAID-5 group concatenated with a 2x3TB RAID-1 group (in one volume). That would give you a 12 TB volume with single redundancy.

Your desired configuration would of course give you 9 TB total (between the two volumes).

I would like to add that you really should maintain a backup, and not depend on the mirror. RAID-1 has its benefits (simpler recovery is one of them). But it's still not enough to keep your data safe.

Hi Stephen.
That's what I had read about, but wanted to be sure had it righ, been a while since done anything like this. Thank you for confirming it for me.
I do have three other separate backups, a little paranoid, I know, but I have files I do not want to loose.
Just thought this system would enable me to add and access easily.
Thanks again for your help.
Regards Suzan

You don't need to delete the initial volume after switching to FlexRAID if you first initiallize with only one pair of drives then switch to FlexRAID before you add the other two. The first two drives will be the primary volume, containing apps and user folders (if you use any).
