RAID 5 128K Sequential Read/Write

The 128K read sequential speed reflects the maximum sequential throughput of the SSD using a file size encountered in an enterprise scenario. The Micron array reaches a sequential read speed of 6,031 MB/s at QD256, while the HGST array peaks at 5,385 MB/s.

We observe slower write speeds at lower queue depths and then a missive increase over QD32. The HGST array averages 2,998 MB/s, while the Microns average 2,205 MB/s

Latency drops significantly as we reach higher queue depths.
