Toshiba MG04 Enterprise 5TB HDD Review

4k Random Read/Write




Each level tested includes 300 data points (five minutes of one second reports) to illustrate performance variability. The line for each queue depth represents the average speed reported during the five-minute interval. We include a smaller embedded chart that lists performance at the highest load for easy interpretation.


4K random speed measurements are an important metric when comparing drive performance, as the hardest type of file access for any storage solution to master is small-file random. 4K random performance is a heavily marketed figure, and is one of the most sought-after performance specifications.


The Toshiba MG04 takes a slight lead over the He6 in the random read workload. The MG04 also scales well by quickly delivering higher performance as we add load, and topping out at QD64.






Our Latency vs IOPS charts compare the amount of performance attained from each solution at specific latency measurements. Many applications have specific latency requirements. These charts present relevant metrics in an easy-to-read manner for readers who are familiar with their application requirements. The HDDs that are lowest and furthest to the right exhibit the most desirable latency characteristics.


The Toshiba MG04 delivers the most performance within a lower latency envelope.




The MG04 takes a commanding lead of 53 IOPS over the Seagate Enterprise Capacity. The He6, optimized for low power consumption, places a distant third with random write activity.






The MG04 continues to exhibit excellent Latency v IOPS performance.




Our write percentage testing illustrates the varying performance of each solution with mixed workloads. The 100% column to the right is a pure write workload of the 4k file size, and 0% represents a pure 4k read workload.


The MG04 leverages its impressive performance to deliver a win across the spectrum of mixed read/write random workloads. The He6 starts out with a higher random read speed than the Seagate Enterprise Capacity, but they trade positions as we mix in more write activity.




We record power consumption measurements during our test run at QD256. It is important to consider Watts-per-TB during power analysis due to the varying capacities in the test pool.


The MG04 draws less power than the Seagate Enterprise Capacity, but comes in a distant second to the He6.






We generate IOPS-to-Watts measurements from data recorded during the test period. The MG04 edges out the He6 in efficiency in the 4k write workload, which is quite the feat considering the He6's power-conservative slant.
