LVM multi raid setup?

[I8NY]

I know Linux has great capabilities over the years of using it but I can't seem to find an exact name or setup for this scenario. I want to do Matrix RAID (that is not the correct general name but it was as close as I got) on two HDD. I want to put the OS in RAID 1 for redundancy and then have another partition or folder as RAID 0 for TV recordings both on two HDD. BIOS RAID won't support this and I don't want to get a $150 RAID card so I want Linux to do a software RAID using LVM and/or something I don't know about.

With mdadm it's possible to create RAID setups by combining partitions instead of devices/hard disks.

Great, I'll just make two partition on each HDD and join 2 partitions in RAID 1 and 2 others in RAID 0.
