The access times of hard drives are dependent on a lot of factors including Seek time, Rotational Delay and Spin-up time. All these characteristics vary a great deal according to the location and the size of the data being requested.
Its pretty hard to tell read and writes apart in the chart above. That’s because Access times for both operations is virtually the same. In fact the average in both cases comes down to 18.6 ms, which is very decent for a portable 2.5” hard drive. Notice how the access time tends to increase as you get closer to the edge. A similar trend would have been visible in the transfer speeds graph on the previous page as well if the hard drive wasn’t being bottlenecked by the interface.
