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.

The first time we ran into asynchronous flash paired with a SandForce SF-2281 was when we tested the OCZ Agility 3. The Agility 3 and RevoDrive 3 X2 share the same flash type, asynchronous ONFi 1.x. On the chart we can see how async flash affects the performance of the SF-2281 controller by comparing the Agility 3 to the Vertex 3. When data is populating the async flash the drive slows considerably.
Moving on to the RevoDrive 2 X3, we see a double whammy hit, the first from the lack of TRIM and the second from the choice of asynchronous flash. With the RevoDrive 3 X2 populated with 50% data capacity the drive slows to below a single OCZ Vertex 3 240GB drive. This is a really big problem for users looking for ultimate performance and paying a premium price for it.
