The PCMark 10 Data Drive Benchmark has been designed to test drives that are used for storing files rather than applications. You can also use this test with NAS drives, USB sticks, memory cards, and other external storage devices.

The Data Drive Benchmark uses 3 traces, running 3 passes with each trace.

Trace 1. Copying 339 JPEG files, 2.37 GB in total, onto the target drive (write test).
Trace 2. Making a copy of the JPEG files (read-write test).
Trace 3. Copying the JPEG files to another drive (read test)

Here we show the total bandwidth performance for each of the individual traces.

In the PCMark 10 Data Drive Benchmark, the best performance came using the read-write test trace (173MB/s). The drive produced an overall bandwidth for the test of 160MB/s.
