8K Random Read/Write




8K random read and write speed is a metric that is not tested for consumer use, but for enterprise environments this is an important aspect of performance. With several different workloads relying heavily upon 8K performance, we include this as a standard with each evaluation. Many of our Server Emulations below will also test 8K performance with various mixed read/write workloads.


The Constellation ES.3 delivers an average of 190 IOPS at QD256, again exhibiting excellent random read speed.




The average 8K random write speed of the Constellation ES.3 is 199 IOPS at QD256.




The Constellation ES.3 again leverages its tremendous random read speed to best the competition in this test.




The Constellation ES.3 delivers 97.66% of I/O's (58,541) at 100-200ms, and the remaining 1,401 I/O's (2.3%) at 200-400ms.




Power consumption for the Constellation ES.3 averages 10.91 Watts during the test period.






The Constellation ES.3 delivers solid performance with an average of 18 IOPS per Watt in 8K random write, and 17 IOPS per Watt for 8K random read access.
