PCMark Vantage - Drives with Data Testing

 

For a complete breakdown on the Drives with Data Testing, please read this article. You will be able to perform this test at home with the files provided in the article; full instructions are included.

 

- Brief Methodology

 

SSDs perform differently when used for a period of time, and when data is already present on the drive. The purpose of the Drives with Data Testing is to show how a drive performs in these 'dirty' states. SSDs also need time to recover, either with TRIM, or onboard garbage collection methods.

 

Drives with Data Testing - 25%, 50%, 75% Full States and Dirty / Empty Test

Files needed for 60 (64GB), 120 (128GB), 240 (256GB)

60GB Fill - 15GB, 30GB, 45GB

120GB Fill - 30GB, 60GB, 90GB

240GB Fill - 60GB, 120GB, 160GB

Empty but Dirty - a test run just after the fill tests, and shows if a drive needs time to recover, or if performance is instantly restored.

With data on the drive, the Q Series Pro runs the same tests very well. Using the 50% of flash populated with data as our marker, the Q Series Pro runs faster than any other drive on the chart. This is an important benchmark because it shows results in a state that is closer to real-world use. It's rare to get a result in the 50K range, but the Q Series Pro breaks into the 55Ks.
