Iometer Results (Part 1)
Lastly, we put the drives through the rigorous grind of Iometer, with different workloads and I/O queue depths. We have chosen to show results from a queue depth of 1 to 5 as this better represents the workloads a typical consumer might face.
Considering the WD Black2’s underwhelming performance thus far, we were not surprised to find that it was the worst performing drive. As seen on CrystalDiskMark and AS SSD, the SSD drive on the WD Black2 suffers from poor write performance and it was no different on Iometer as its 64k streaming write performance was particularly poor - recording just barely half the IOPs of the second-lowest performing SSD, the Crucial M500.
Update: Unsurprisingly, the hybrid hard disk drive was no match for the WD Black2 and the rest of the SSDs on Iometer, and the difference in performance is staggering, especially on the intensive "File" and "Web Server" workloads.
