128k Sequential Read/Write

The 128k sequential speeds reflect the maximum sequential throughput of the HDD using a realistic file size encountered in an enterprise scenario.

 

The Toshiba AL13SE averages 184 MB/s of sequential read speed, while the Seagate v7 takes the lead with its average of 195 MB/s.

The AL13SE averages 182 MB/s of sequential write speed, and the Seagate leads again with 195 MB/s.

Though the AL13SE trails in the pure read and write workloads, we can see that it handles mixed read/write data very well and dominates the middle of the chart.

The Seagate v7 provides lower latency during the 100 percent write testing.

The Seagate v7 draws more power during the write test, but the IOPS to Watts testing reveals this is in line with the increase in performance.

The AL13SE and the v7 deliver similar test results in IOPS per Watt testing for sequential data, proving that the slightly higher power consumption of the v7 is offset by the increased performance.
