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 Turbo SSHD averages 587 IOPS at QD256, while the Enterprise Performance averages 469 IOPS. The MK1401 pulls off 513 IOPS at QD256.
The Seagate Turbo SSHD delivers a lower latency distribution than the competing drives.
The Turbo SSHD averages 7.57 Watts, closely matched to the Enterprise Performance, but above the MK1401.
The Seagate Turbo SSHD matches the MK1401 in IOPS-per-Watt during this test.
The File Server profile represents typical file server workloads. This profile tests a wide variety of different file sizes simultaneously to simulate multiple users with an 80% read and 20% write distribution.
The Turbo SSHD averages 131 IOPS, while the Red averages 182 IOPS at QD256.
All of the drives are closely matched during this test, with the MK1401 providing the best latency.
The Turbo SSHD and Enterprise Performance 15K are closely matched in power consumption for this workload.
The MK1401 again pulls off the win in the IOPS-to-Watts testing, due to its single platter design.
