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.
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
In this set of tests we see the overall performance from the PCMark Vantage HDD tests, but with data on the drive in 25%, 50% and 75% full states. The top and bottom numbers on the chart are with the drives void of data, the top in a clean state and the bottom in a dirty state.
The OCZ Vertex 3 120GB drive slows down as data is added to the drive. The lowest result in our testing of the 120GB Vertex 3 still shows the drive outperforming the Corsair Performance 3 in all but the 75% full state. Personally I feel this is the next frontier for SandForce and other controller developers to conquer, since the drop off in performance is so radical.
