RAID 5 128K Sequential Read/Write

The 128K sequential speeds reflect the maximum sequential throughput of the HDD using a file size encountered in normal NAS usage.

 

The WD Reds take a huge hit in their sequential write performance in RAID 5; this is truly telling of the major performance differences between these two arrays. The Reds average only 106 MB/s, while the Se chugs along at a blistering 483 MB/s.

The read performance is again largely unaffected by RAID 5, with the Se's averaging 470 MB/s, and the Red array averaging 416 MB/s.

The Se's easily outperforms the Reds as we mix in heavier write workloads.

The Se delivers all of its I/O in a nice tight latency range.
