Define "effective".
There are only two choices with [Mac OS X's] software raid - increase
speed (RAID 0/stripe), or improved resilience (RAID 1/mirror).
RAID 1 will halve your storage capacity, and slow things down a bit, but
in theory you'd be able to recover from the failure of any 1 drive.
RAID 0 will speed things up, but if any one drive fails, you lose all
partitions that used that drive.
If it's reliability you're after, personally I'd ditch the RAID and set
up a nightly rsync backups between two identical partitions.
