This is almost as bad as RAID-0: while you don't lose everything
when a disk dies, you do still lose up to half the data.  Also since
the data will be (usually -- there are striping options for LVM)
linearly organised across the devices, there is none of the
performance benefit that RAID-0 or RAID-1 would provide.

I would recommend a RAID-1 of at least two devices, then LVM on top
of that for flexibility.

Cheers,
Andy
