Sequential read for both the 6TB and 5TB arrays was rather impressive reaching 440 MB/s and 448 MB/s.

Moving over to sequential write, the 5TB and 6TB arrays again carried a large performance advantage over the 4TB array. Here we have 422 MB/s for the 5TB, and 448 MB/s for the 6TB array.

Read latency for both the 5TB and 6TB arrays was considerably better than expected. As you can see, they both managed near 9ms at QD32, while the 4TB array chugged along slower at 14ms at QD32.

Write latency was quite similar to the read latency, where we found the 5TB and 6TB arrays being much quicker than the 4TB setup.
