If one of the disks fail, you probably lose it all. That said, it can still be advantageous to use lvm in this context because of the flexibility down the road -- if you need to adjust the sizes of yourpartitions, you can do so easily.there is no other advantage and in fact there may be disadvantages because the additional number of disks increases the odds of encountering a failure.
Frankly, this "advantage" is pretty weak, IMO. So far, I see no real
need for it. I suppose that there are those who constantly tweak
their systems. The advantage usually touted is that one can easily
add new discs. But I'd rather have one large disc than several small
ones, anyway. I suppose one who constantly installed one OS after
another and wanted ease of "repartitioning" could use it. So far,
I see no advantage for normal users. I am astounded that some distros
use LVM as the default.

I can explain it for you, but I can't understand it for you.
I speak only for myself, and I am unanimous in that!
