This test emulates Database and On-Line Transaction Processing (OLTP) workloads. OLTP is in essence the processing of transactions such as credit cards and high frequency trading in the financial sector. Databases are the bread and butter of many deployments. These are demanding 8K random workloads with a 66% read and 33% write distribution that can bring even the highest performing solutions down to earth.
The Seagate averages 110 IOPS at QD256, while the WD Red averages 144 IOPS.
The Seagate NAS HDD provides a higher latency range in this workload. The Red exhibits an almost bi-modal distribution of write latency in this mixed workload, with a distribution on either end of the latency spectrum.
The Seagate averages a much lower 5.12 Watts, while the Red averages 6.59 Watts during the test period.
The Seagate averages 21 IOPS per Watt in our Database/OLTP testing, scoring very close to the WD Red.
The File Server profile represents typical file server workloads that are very relevant to NAS usage. This profile tests a wide variety of different file sizes simultaneously to simulate multiple users with an 80% read and 20% write distribution.
The Seagate averages 131 IOPS, while the Red averages 182 IOPS at QD256.
The Seagate NAS HDD falls behind the WD Red in latency performance with the fileserver profile.
The Seagate NAS averages 5.2 Watts during the test, while the Red averages a much higher 6.97 Watts.
The Seagate averages 19.1 IOPS per Watt, while the Red averages an impressive 25.63 IOPS per Watt during the measurement window.
