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.

Last year we found a bit of a flaw in the way PCMark Vantage tested SSDs, so we came up with a way to correct the issue. When SSDs have data on them they slow down. The amount they slow down is the variable, though, and in this series of tests we can determine how much a drive slows.


Using the 50% full capacity as the reference point, we see the V30 performance worse than the Vertex 3 120GB. It actually dips down to the same performance as the 128GB Crucial m4 range.
