    The single HDD will easily provide more battery life. SSDs aren't much more power efficient, they use more CPU than HDDs, and using a software RAID uses even more CPU than that, reducing battery life further.

    Are you saying that an SSD would use more CPU than an HDD even without software RAID? Why is that?

    1 SSD would use more power than 1 HD. They are not very power friendly, on top of that they use more CPU, which also in turn, uses more power.

    I'm curious now. Why would one SSD require more CPU than an HDD? I though OSX accessed the SSD just as if it were an HDD.
