The point\nof far-copies is that it allows the first section (normally first half)\nto be layed out in normal raid0 style, and thus provide raid0 sequential\nread performance.\n\nUnfortunately, the read balancing in raid10 makes some poor decisions\nfor far-copies arrays and you don\u0027t get the desired performance.
