Server workloads rely heavily upon 8k performance and we include this as a standard with each evaluation. Many of our server workloads also test 8k performance with various mixed read/write workloads.

 

The average 8k random read speed of the WD Red Pro is 162 IOPS at QD256; the WD SE is slightly behind with 155 IOPS, the WD Red offers 135 IOPS, and the Seagate NAS HDD provides 92 IOPS.

The latency gap between the WD products shrinks with 8k random workloads, while the Seagate NAS HDD continues to lag behind.

The WD Red Pro averages 193 IOPS at QD256, the WD SE offers an ever-so-slightly faster 196 IOPS, the WD Red provides 146 IOPS, and the Seagate NAS HDD averages 116 IOPS.

The similarities between the WD Red Pro and the SE are very clear in mixed random workload testing.
