Mirror and stripe on a partition basis?

Hello archers,

I was wondering wether it is possible or not to create some  sort of soft raid on a partition basis instead of per disk.

Given a system with 2x3TB HDD's, I would like to have some partitions mirrored and others striped so that I can have redundancy for important data but at the same time don't have to sacrifice all that much disk space and just stripe the remaining part that is supposed to only host data that would not be much of a loss in case of disk failure.

If a setup like this is possible, could you kindly point me into the direction as to how to do it or what to utlilize to achieve it?

Thanks a bunch.

Using just partitions should be possible.
