If you need that, use raidframe (raid0).

Nothing good.

Both ccd and raidframe (I have no experience with lvm, so no comment
on that one) provide a virtual drive.   That drive can be partitioned
using whatever mechanism you like (MBR, disklabel, GPT) - anything that
would work on a physical drive.
