Can you give the output of pvdisplay, vgdisplay, and lvdisplay?

Also, did you align the pv's to 4K sectors when you partitioned?

The particular drives (hardware) you are using have known performance issues; there are a number of reports in Western Digital's forums confirming this, for more than just Linux.
