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.
HDD1 - Windows Defender
HDD2 - Gaming
HDD3 - Windows Photo Gallery
HDD4 - Vista Startup
HDD5 - Windows Movie Maker
HDD6 - Windows Media Center
HDD7 - Windows Media Player
HDD8 - Application Loading
The SF-2281 will fall from the top spot one day but today is not it. Even though the Corsair Performance Pro delivers class leading performance when empty it fails to keep that level of performance when filled with data. In the 50% fill test the performance drops to around 46K Marks, a very large decline. The SF-2281 controlled Vertex 3 has a pretty big drop of its own, down to 51K when half full, but that isn't as low as the Performance Pro.
We had very high hopes that the Performance Pro would follow the Performance 3's performance envelope, the shape of the graph produced by the product results. If you look at the Performance 3 numbers on the chart you see steady performance in all tests without a major decline in delivered speed. We still feel this is the future of solid state drives, now we just need to convince those actually designing products to do what we want!
Like I stated, we had really high hopes going into this series of tests. If the Performance Pro would have pulled off solid 80K+ numbers in all of the tests we would have jumped for joy but our dreams didn't quite make it into reality this time around.
