Samsung Portable SSD T9 4TB Review

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 4TB T9 handles the PCMark 10 Data Drive Benchmark pretty well. Out of the three tests, the drive does best in the read-write test where it sits in the top 5 of drives tested. It doesn't seem to handle either the read test or the write test anywhere near as well. But even so, it still makes it into the top 5 drives for overall bandwidth.
