The thin grey lines between the small green dots (every dot is one of the 1000 samples) should show the chronological succession of the access time benchmarking test. ![]() All other samples show an access time between 7 ms and 30 ms. One sample has an access time of 105 ms and 3 samples of ≈ 90 ms. We see only 4 outliers (marked with red circles) in 1000 samples. The average access time (the time it takes before the drive can actually transfer data from a random track.) is also normal (≈ 17 ms). Read/write rate outermost track: 1260 B/sĪs a result the read rate (blue) and the write rate (pink) slightly decreases from the outermost tracks on the left (≈ 84 MB/s) to the innermost tracks on the right (≈ 45 MB/s). Radius of the innermost track: 1 inch -> track length: 6,3 inches Radius of the outermost track: 2 inches -> track length: 12,6 inches With one rotation of the platter the read/write head can read/write more bits on the outermost track than the innermost track in the same time. Therefore the outermost track contains more bits than the innermost track. ![]() Usually the linear density of magnetic areas holding a bit is almost constant on the whole platter. The benchmark shows the normal behavior of a spinning hard drive. ![]() The SMART Data shows a normal degradation of an approx. Just to give a correct interpretation of the SMART Data and the benchmark and clear up the misunderstandings revealed in some answers, comments and the question:
