Finally, we look at the I/O response times for the workloads reported on the previous page. Expectedly, considering its performance on the earlier page, the WD Black2 record appropriately high response times. Its graphs show that it was consistently one of the slower drives.

Update: Unsurprisingly, considering the hybrid hard disk drive's poor performance on the previous page, we fully expected to see it record high response times and this was exactly what we got. Its recorded response times were many times more than that of the flash-based drives - so much so, that we had to forego presenting them in these graphs. Clearly, the hybrid drive was made to compete with traditional hard drives and not these flash-based beasts. Here's an example.
