In litteral terms, you can do software raid on linux with 1 HD and two
partitions.  However, it probably hurts performance, rather than improving
it.  The multiple heads on a hard drive all line up vertically and scan
what's called a cyllinder (multiple sectors stacked on top of each other).
They cannot read two partitions at the same time.  You could test out
software raid with two partitions, but I don't think you'd be too happy with
it.  You can probably get RAID 1 going with a very slight advantage.  It
won't save you in case your drive fails entirely, but if you start to get
bad sectors or filesystem errors, at least your HD is backed up on another
partition.
