8k Random Read/Write

8k random read and write speed is a metric that is not tested for consumer use, but is an important aspect of performance for enterprise environments. 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 Toshiba AL13SE delivers an average of 389 IOPS at QD256, falling slightly to the Seagate v7's average of 404 IOPS.

The average 8k random write speed of the AL13SE is 377 IOPS at QD256. The v7 measures a lower 361 IOPS at QD256, with the two drives again flip-flopping positions from read to write testing.

The AL13SE scores very well as we mix in more write activity, with the tipping point occurring at a 30 percent write mixture and continuing until it is a full 100 percent write workload.

The AL13SE nudges the v7 with a slightly lower latency range with write activity.

The difference in power consumption for the AL13SE and the v7 is nearly indistinguishable in this test, with less than 0.1 watts separating the two drives.

The two drives again trade blows with efficiency. The AL13SE leads in write workloads, while the v7 leads in read workloads. This is rather predictable considering the performance results above.
