Actually, I discovered that with 4 drives, you're much better off using an
odd stripe size. (not a power of two) This is because of how the cylinder
groups are laid out, they'll all end up on one drive.

You may want to ask Greg Lehey (grog@lemis.com) for more info about this, as
I can't remember exactly what he came up with for an optimum stripe size.
