Trace 2: Making a copy of the JPEG files (read-write test).

Trace 1: Copying 339 JPEG files, 2.37 GB in total, in to the target drive (write test).

The Data Drive Benchmark uses 3 traces, running 3 passes with each trace. You can also use this test with NAS drives, USB sticks, memory cards, and other external storage devices. The Data Drive Benchmark is designed to test drives that are used for storing files rather than applications. PCMark 10 – Data Drive Benchmark Results: So, the take home message here is that PCMark 10 takes advantage of all available threads and uses newer real-world traces. This should play top the strengths of NVMe devices that have come out in recent years as they were designed to handle multiple queues at the same time.

Most modern software has been written to be a muilthreaded solution where it can push IOs from multiple threads.

The CPU thread count used by the benchmark does not equal to the queue depth seen by the storage device. That means that the thread sending an I/O does not sit waiting for it to complete, but can instead queue more I/O to match the queue depth in the recorded trace. The I/O in both PCMark 8 and PCMark 10 is asynchronous. About half the available cores/threads are being used for generating the data needed for I/O and the other half are tasked with sending out I/Os. PCMark 10 Storage uses all the CPU cores available on the platform being tested and has been validated to support up to 5GB/s bandwidth. We are by no means living in the single-core era thanks to corporations like AMD offering CPUs with higher core counts than ever before. PCMark 8 was originally introduced in 2013 and the storage test uses only one thread to do everything.
