Hi Michael.  Ignoring LVM for a moment...

*Sigh*. I meant to go on to point out that LVM further abstracts away the hardware making it even harder to establish where the fastest part of the physical disk is.

Similarly virtual hosts have little chance of trying to establish the physical nature of the device holding their filesystems.
