Base Product Specifications


The five major measurements of base performance of any storage solution are latency, random read/write and sequential read/write speed. These are the most common measurements posted by manufacturers to advertise storage performance. We will cover the latency and sequential read and write on this page, and random performance on the following page. We begin with a measurement of the latency of the device. The industry standard for measurement of latency is 4K Random Access at a Queue Depth (QD) of one.




The drive exhibits consistent latency across the different amounts of QD, and scales nicely as we enter the higher QD. The drive averages 4.9ms at a QD1.




The 128K sequential read speeds reflect the maximum sequential throughput of the drive using a realistic file size actually encountered in an enterprise scenario. Here we can see that the drive reads very steadily at an average of 1545 IOPS, or roughly 190MB/s.




The HDD reaches an average of 1498 IOPS, or 185MB/s in 128K sequential writes at QD32. There is a bit of variability here, but the scale of the chart is very low. There is only a separation of 65 IOPS between the highest and lowest results in this test.
