In our 128KB Sequential tests, the DC P4800X peaked at the QD2 mark at 2,680MB/s before finishing the test run at 2,434MB/s – quite a steep drop off in performance at QD32. Writes also peaked at QD2 at 2,410MB/s, but the write performance was much more consistent finishing the test at 2,407MB/s.

We also tested the drive at a much deeper queue depth of 256 in various block sizes to see how the drive performed when pushed hard. Both the read and write figures surpassed the official figures, with the tested read score topping out at 2,913MB/s at the end of the test. The write performance was much more erratic, dropping to 2,065MB/s at one point before recovering to finish the test at 2,372MB/s.
