18 Economic Benefits of SMR drives SMR Drives Shingled Technology increases capacity of platter by 30-40% Write tracks are overlapped by up to 50% of write width Read head is much smaller & can reliably read narrower tracks SMR Drives are optimal for object stores as most data is static/worm Updates require special intelligence and may be expensive in terms of performance Wide tracks in each band are often reserved for updates CS A200 manages SMR Drives directly to optimize workflow & caching Read Head Write Head Updates destroy portion of next track
