SanDisk Extreme Pro Portable SSD 1TB 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 SanDisk Extreme Pro SSD sits comfortably in mid-table for all three trace tests.


With a bandwidth figure of 161MB/s for the SanDisk Extreme Pro, the drive sits mid-way in our result table. It’s 39MB/s slower than WD’s MyPassport Drive and 26MB/s faster than the Patriot PXD 1TB drive.
