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.

In our own version of Vantage we add data to the drive to simulate what type of performance you would see in the real-world.
Using the drive half full (the middle blue plot on the graph) we can see how the 520 Series with synchronous flash compares to the OCZ Agility 3 with asynchronous flash. There is a large performance difference between the two, but the OCZ Vertex 3, another synchronous flash drive using IMFT 25nm flash, is very close to the 520 Series.
