I'm not sure what @snaptec means by this.
Perhaps he was comparing two 4 disk scenarios and typed 8 in the example below.
With 4 disks striped in two mirrored vdev's, you'd have 8TB of space (same as 4x4TB in RAIDz2). If you're using it for iSCSI storage, the recommendation is to use no more than 50% of your storage. Perhaps, that's how snaptec arrived at 4TB.

If you need more iops f.e. For virtualization storage and don't need much space go witch 8 drives in 4 mirrored vdevs.
You will just get 4TB out of that.
