Another option here would be a 4 disk RAID1, on the basis that it's
giving you a simple, highly redundant setup.
If the performance requirement is such that you need the speed of RAID5,
10 etc., then you probably need to be looking at adding RAM or otherwise
avoiding swapping in the first place.
The fact that you mention you are using partitions on disks that
possibly have other partions doing other things, means raw performance
will be compromised anyway.
