Workload Performance Testing

Database Workload

The products we're testing today fit a special slice of the enterprise market where the workload requires high transaction rates at very high queue depths. Busy database and OLTP servers are more common for these workloads, but high-frequency trading also falls into this category.

The two ZET drives scale well under this workload with the larger model showing a slight advantage thanks to its higher random write speed.

The drives show storage performance up to the point where increased latency compounds and reduces the transaction rate.

OLTP Workload

The Online Transaction Processing (OLTP) test is similar to the database test but uses larger data block sizes for the high transaction rate workload.

Email Workload

It would be difficult to recommend the products we tested today for email servers, but we like to use a standard set of tests that allows our readers to compare all products against the same workloads.

Archive Workload

The archival test is by far the most brutal in the workload series. This test uses several block sizes with both sequential and random access. The access specification (workload) comes from Dell's 2016-updated storage test suite used by the company for internal testing.

Even with the lowest latency NVMe SSDs shipping today, the preconditioning shows varied results with a lot of inconsistency.
