This test consists of 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 2TB drive delivers an impressive 223 IOPS at QD256 during this demanding test. The 6TB also offers great performance with 210 IOPS, and the ES.3 provides 201 IOPS.
The 6TB Enterprise Capacity came close in performance, but the 2TB version manages to deliver better latency-v-IOPS characteristics.
The 2TB Enterprise Capacity requires an average of 4.65 watts during the transactional workload.
The 2TB Enterprise Capacity provides an outstanding 47 IOPS-per-watt.
The file server workload consists of typical file server activity. This profile tests a wide variety of different file sizes simultaneously, with an 80% read and 20% write distribution.
The 2TB Enterprise Capacity provides 197 IOPS at QD256, followed closely by the 6TB variant with 191 IOPS. The ES.3 averages 187 IOPS.
The ES.3 manages to come in second in latency-v-IOPS measurements.
The 2TB drive continues to offer amazingly low power consumption with an average of 4.65 watts during the fileserver workload.
The 2TB drive offers 42 IOPS-per-watt during the measurement window.
