This test emulates Database and On-Line Transaction Processing (OLTP) workloads. OLTP is the processing of transactions such as credit cards and high frequency trading in the financial sector. Databases are the bread and butter of many enterprise deployments. These demanding 8k random workloads with a 66 percent read and 33 percent write distribution bring even the best solutions down to earth.


The Seagate v4 averages 282 IOPS, the He6 235 IOPS, and the 7K4000 averages 280 IOPS at QD256.






The Seagate v4 averages 10.08 watts, the He6 averages 7.17 watts, and the 7K4000 requires 8.67 watts.




The Seagate v4 averages 28 IOPS-per-Watt, and the He6 averages of 32 IOPS-per-Watt, which is matched by the 32 IOPS-per-Watt from the 7K4000. The Seagate v4 closes the gap in mixed workloads, with only a scant four IOPS-per-Watt difference during the workload.



File Server




The file server profile represents typical file server workloads. This profile tests a wide variety of different file sizes simultaneously with an 80% read and 20% write distribution.


The Seagate v4 averages 254 IOPS at QD256, the He6 delivers an average of 230 IOPS, and the 7K4000 averages a leading 282 IOPS.






The Seagate v4 averages 10.5 watts, the He6 averages of 7.5 watts, and the 7K4000 averages 9 watts.




Once again, the Seagate v4 comes within striking distance during a mixed workload.
