My goal is to use SoftRAID Lite to create a mirror of my two RAID-0 sets.
I have two LaCie 4TB 2big Thunderbolt enclosures; named BIG-1 and BIG-2. Each enclosure has two 2TB disks.
BIG-1 enclosure configuration
BIG-1-1 (RAID-0) uses 1TB on each 2TB disks for a total of 2TB.
BIG-1-2 (RAID-0) uses 1TB on each 2TB disks for a total of 2TB.
I want to mirror BIG-1-1 and BIG-1-2 with my BIG-2 enclosure.
I setup BIG-2 same as I did for BIG-1... thus I would have
BIG-2 enclosure configuration
BIG-2-1 (RAID-0) uses 1TB on each 2TB disks for a total of 2TB.
BIG-2-2 (RAID-0) uses 1TB on each 2TB disks for a total of 2TB.
So essentially I'm wanting the following setup
BIG-1 mirrored by BIG-2
How do I go about mirroring
1) BIG-1-1 and BIG-2-1
and
2) BIG-1-2 and BIG-2-2
Please respond with how I can accomplish this.
So far all I've been able to configure is by selecting 1TB on each of BIG-1's two disks and 1TB on each of BIG-2's two disks and selecting "Mirror" (RAID-1). However this seems to me from what SoftRAID Lite is display to me is a Volume of 1TB that had 3 mirrors. Thus the actual performance I get is the speed of a single disk.
What I wish for is to have the speed provided by a striped set of two disks, and to have this striped set of two disks mirrored on another striped set of two disks.
Question: Can I in fact mirror two Striped sets after having setup the two Striped sets or is this done another way if at all ?
I hope I've made myself clear.
I attach a rough sketch to hopefully clarify what my goal is for mirroring a pair of two Striped sets.
Thank you.

SoftRAID Lite only supports RAID 1 or 0. To get RAID 1+0, you need the full version.
What you do is initialize the 4 disks, then create a new volume and select RAID 1+0. Very simple. There is no need to try to "layer" volumes or anything more complicated than creating the volume.

Sounds like you are trying to create RAID 0+1 config. Even the full version of SoftRAID does not support this config; only a RAID 1+0, that is, a stripe (RAID 0) of 2 RAID 1 mirrored sets.
