The advantage would be you could use the other half of the 1Tb drive for something else; it just would not be protected.
You should not see any significant speed reduction, especially with a good hardware card. You are just writing the same data to two drives; no fancy calculations, no striping.
Yes you can do live, but dynamic disk have only 1 partition, they use volume, so you create 2 volumes of 500 gb on the Tetra, and you mirror one with the 500 volume on the other disk.


as an other example you can extend also the volume to 3 differents size of disks , usefull for server when you want to expend, but in that case if a disk fail, you lost everything
