Should I use LVM or onboard RAID for redundant storage?

What's the most sensible way to add redundant storage to an existing Linux system using LVM?

I've got a Redhat FC4 system with a single physical 80GB SATA drive. The redhat installation system defaulted to an LVM configuration, which I'm not very familiar with. I'm used to regular old partitions.
Reading up on LVM, though, it sounds pretty flexible. What is the most sensible option for adding an additional drive as redundant storage to this system?
I was planning on buying another 80GB SATA drive, plugging it in, and trying the onboard BIOS RAID utility out. If possible, I was going to create a RAID set with the two drives, and, if possible, let the RAID utility duplicate the first drive onto the blank one.
The above would tie me to the machine's hardware, though (?). Is there a more sensible way to do redundant storage with LVM?
What's the most sensible way to do this that would allow me to easily swap out one of these drives with another if it died?
