2. Partition alignment.  If you're using classic MBR slices, everything gets misaligned by 63 sectors, making it impossible for 
the controller to optimize both reads and writes.  If the array is used for secondary storage, simply don't use an MBR scheme.  If 
it's used for primary storage, try using GPT instead and setting up your partitions so that they are aligned to large power-of-2 
boundaries.
