8k Random Read/Write
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 2TB drive is 209 IOPS at QD256, and the 6TB comes in second with 226 IOPS. The 4TB ES.3 comes in third with 199 IOPS at QD256.
The 2TB drive continues to take a solid lead in latency-v-IOPS measurements.
The 2TB Enterprise Capacity averages 243 IOPS at QD256, and the 6TB provides 226 IOPS. The ES.3 lags behind the newer drives again with an average of 199 IOPS.
The 2TB Enterprise Capacity continues to deliver excellent mixed-random performance.
Power consumption for the 2TB drive is very impressive with an average of 4.84 watts.
The 2.5" Enterprise Capacity provides 50 IOPS-per-watt with 8k write activity, and 42 IOPS-per-watt during read activity.
