LVM is only going to help you share I/O load between drives if you are
using a non-linear RAID on top of LVM.  Using LVM to glob drives
together to make one large partition effectively fills the first
drive, then the next, etc(unless your FS is fragmented).  Having two
drives on the same IDE cable will hurt your performance, also.

Hope that helps..?
