IOMeter - Sequential Performance with QD




Sequential read started strong for the WD Black, just shy of 170 MB/s. As the QD increases, the drive responds by increasing sustained performance near 180 MB/s.




Sequential write had the WD Black showing equal performance. Here we have the drive touching close to 180 MB/s across the entire QD range.




In this test, we write sequentially to the entire LBA range of the HDD to explore the performance of the HDD's with sequential activity. Here we find the WD Black showing consistent performance across the entire LBA range. In comparison, notice how the Seagate Desktop HDD carries a raindrop appearance across the chart.
