RAID 0 128K Sequential Read/Write

The 128K read sequential speeds reflects the maximum sequential throughput of the SSD using a file size encountered in an enterprise scenario. The Micron's pull ahead in this test, leveraging their impressive read speed, topping out at 6,080 MB/s, while the HGST array peaks at 5,875 MB/s. We are clearly bumping up against controller limitations with both SSD arrays saturating the controller.

128k read latency results indicates the HGST SSD's are more nimble at lower Queue Depths, where the controller has fewer devices to manage. Both arrays reach the best IOPS/latency ratio at QD128.

HGST array reaches the maximum speed of the controller with 5,198 MB/s, and peaks as high as 5,645 MB/s at QD256. The Micron array tops out at 2,771 MB/s, which leaves quite a bit of performance lost in the scaling of the controller. With each P400m conservatively rated at 310 MB/s of sequential write speed we should hit at, or above, 4,960 MB/s.
