The difference between O.D. and I.D. (outer diameter vs inner diameter) LBA's is typically a factor of 2. This is why "short-stroking" works as a technique, and another way that people doing competitive benchmarking can screw up and produce misleading numbers. (If you use partitions instead of the whole disk, you have to use the same partition in order to make sure you aren't comparing apples with oranges.)
