Response Times




With the HGST NAS drive leading the chart in our random testing on the previous page, it does not come as much of a surprise to see it also lead the charts in response times. Here we can see the drive is about 24ms quicker at QD32 than the Seagate NAS and 20ms quicker than the WD Red.




Again, with random write, we see similar results. The HGST NAS comes in 40ms quicker than the WD Red at QD32 and 17ms faster than the Seagate NAS.




Moving over to sequential response times, we find the HGST NAS slightly quicker than both competing NAS solutions.




In sequential write testing, the HGST NAS came in at 24ms with the WD Red at 29ms and Seagate NAS touching 28ms.



Power Consumption


Our custom power testing samples each drive for a period of three minutes across each workload. In order to offer more granularity, we sample the power in one-second intervals.




Power consumption for the HGST NAS is a big tradeoff. Here as you can see we start at 8.8 watts in random workloads and jump to 9.2 watts for sequential workloads. This is significantly higher than the WD Red, which peaks at just under 6 watts, and the Seagate NAS that touches 6.4 watts at its peak.
