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


SSD's 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. SSD's 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.




Measuring real-world performance with 50% of the NAND capacity full resulted in nearly identical performance to OCZ's Vector. At 75% full, Extreme II was a little faster than the current Vector 120GB, but down slightly to the 840 Pro.
