Lastly, we look at the I/O response times for the workloads reported on the previous page. In terms of response times, the 64k streaming read and write response times for the WD Black 4TB drive was generally better than the WD Black 1TB and the older 300GB VelociRaptor drive. However, timings took a significant turn for the worse when coming to the file and web server workloads, which also explained its poor IOPs reading in these two workloads on the previous page. As explained, this is likely attributed to the five-platter hard drive design used.
