Four drives deliver a solid 395 IOPS, and performance nearly doubles with the eight-drive array reaching 784 IOPS.

The latency scales as expected, with a slight increase in variability at higher OIO.

Four drives provide 322 IOPS, and eight drives brings that up to 640 IOPS.

The 9361-8i provides lower latency during the test.

As we mix in progressively higher write workloads, the Seagate drives actually provide better scaling between the two arrays.
