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.

Looking at the performance drop off when data is added we see that the NuvoDrive NX goes from 47276 Marks when empty to 35798 Marks when half full. The performance further decreases to just 32K Marks when 75% full, but when all of the added data is deleted TRIM works very well and performance goes back to 43K Marks.
