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, in to 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.
The Samsung T7 Shield doesn't seem to handle the PCMark10 Data Drive Benchmark test too well, sitting in the lower half of the results chart for all three trace tests.
With a bandwidth figure of 145MB/s, the drive sits in the lower half of our result table.
