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, to the target drive (write test – cps1).
- Trace 2. Making a copy of the JPEG files (read-write test- cps2).
- Trace 3. Copying the JPEG files to another drive (read test – cps3)
Here we show the total bandwidth performance for each of the individual traces.
Compared to other drives around it, the My Passport SSD seemed to perform best in the cps2 (read-write test) run.
The My Passport SSD drive trails the Crucial X8 in the overall bandwidth results but is faster than Patriot's PXD drive.
The access time for the My Passport drive is practically the same as Crucial's X8, both drives having much faster access times than the Patriot PXD drive.
