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% read and 33% write distribution bring even the best solutions down to earth.


The Toshiba PX03SN averages 43,118 IOPS; the PX02SS averages 60,240 IOPS at 256 OIO, and the PX02SM averages 43,127 IOPS. The PX03SN makes great strides in performance consistency over the PX02SM.
