8k Random Read/Write
8k random read and write speed is a metric that is not tested for consumer use, but this 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 WD Xe averages 395 IOPS, and the Toshiba AL13SE delivers an average of 389 IOPS at QD256. The Seagate v7 averages 404 IOPS.
The WD Xe exhibits the same tendency for less performance at lower queue depths with random write activity. The Xe delivers 340 IOPS at QD256, the AL13SE is at 377 IOPS, and the v7 measures in at 361 IOPS.
The WD Xe again tops the charts with heavy read activity on the left, but it loses ground as we move to the right.
The wide range of latency is not quite as orderly as the other two drives in the test pool.
The WD Xe again exhibits excellent power consumption with a low average of 7.01 watts. This is nearly a 1.5 watt advantage, a big deal when we stack up hundreds of drives in a production environment.
The WD Xe leans on its stellar power consumption to provide enhanced efficiency.
