128k Sequential Read/Write
We write sequentially to every LBA to highlight performance degradation from the outer to inner tracks of the drive. The drives begin with much higher speed on the outer tracks, and lose speed as they work inward. The varying capacity points in the test pool are evident, and the Toshiba MG04 requires the least time to complete a full pass across the platter due to its lower capacity. The Seagate and HGST models feature the same 6TB's of capacity, but the Seagate completes the test faster due to its increased sequential speed.
128k sequential speed reflects the maximum sequential throughput of the HDD, and is indicative of performance in OLAP, batch processing, streaming, content delivery applications, and backup scenarios. Today's HDDs are increasingly used for sequential workloads as SSDs encroach upon the application space.
The Toshiba MG04 and the Seagate Enterprise Capacity vie for the fastest speed in the 128k sequential testing, with the Seagate coming out on top. The He6 places a distant third.
The Seagate takes the lead in latency performance with sequential read activity.
Sequential write performance is important in tasks such as caching, replication, HPC, and database logging. The MG04 pulls off a slim lead of 1 MB/s over the Enterprise Capacity, and the He6 continues to lag behind with sequential workloads.
The Toshiba and the Seagate are closely matched, and the Seagate exhibits a distributed latency profile at higher queue depths. This variability disappears under sustained workloads.
The mixed-workload sequential test is one of our most demanding tests. Many drives will fare very well on the high-end, but fall short with mixed sequential activity. The Seagate wins six of the read-heavy categories, and the MG04 takes the lead in write-centric workloads.
The Toshiba MG04 provides incredibly low power consumption during the 128k workloads, so much so that we ran the tests three times to verify the results. The MG04 places second to the HGST He6, but draws much less power in comparison to the Seagate offering.
The impressively low power draw of the MG04, and its solid sequential performance, combine to provide a surprisingly competitive efficiency ratio compared to the power-optimized HGST He6.
