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 Toshiba MG03ACA400 delivers an average of 178 IOPS at QD256, again falling into the space between the two competing solutions.
The average 8K random write speed of the Toshiba HDD is 196 IOPS at QD256, only falling behind the V.6 by two IOPS.
The Toshiba MG03ACA400 performs well in comparison to the Western Digital Se, but falls slightly to the Seagate V.6 in the 60-90% range.
Once again, the Toshiba HDD delivers superb latency performance, with 97.70% of I/O's (57,606) at 100-200ms, and the remaining 1,355 I/O's (2.29%) at 200-400ms, edging out the Seagate V.6 by the very slimmest of margins.
Power consumption for the Toshiba MG03ACA400 averages 11.75 Watts during the test period.
The Toshiba averages of 11.72 IOPS per Watt in 8K random write, and 11.75 IOPS per Watt for 8K random read access.
