Creating a RAID-1 of two RAID-0 units

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.
