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.

Unfortunately for Crucial in 2011 and just as SSDs have improved in the last year, so have our testing methods and understanding of what's important for real world performance. This chart introduces a new drive into the mix, the OCZ Agility 3 240GB. The Agility 3 was the first SandForce SATA III drive we tested that used asynchronous flash.
On the surface the Agility 3 performed very well when compared to the Vertex 3 and other SandForce SATA III synchronous flash drives; nearly identical numbers across the board. That was until we started adding data to the drive and at that point the performance dropped rapidly.
This rapid decline in performance also takes its toll on the Crucial m4 even though the m4 uses synchronous flash. Here we see that with each drive being filled to 50% of capacity, the Crucial m4 is still slower than the OCZ Vertex 3 by a sizable amount. The m4 is faster than the Agility 3 by about the same margin, though.
