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.

For me and many of our readers, this is the real world test that matters most. I'd speculate that most users keep their SSD at around 50% full. At that fill rate the Corsair Force GT is faster than the Vertex 3 when we tested it and a lot faster than the Force 3.


There are really two distinct Team SandForce products this year, the async and the sync and that is what we are looking at here. The async drives cost a lot less than the sync drives because asynchronous flash costs less than synchronous flash. As you can see here, the two products really aren't in the same league when tested under real world conditions.


I've seen a lot of websites talk about the incompressible data differences, but fail to show how that relates to your real world usage. This test and this chart show what you can expect. If you are looking for a true, next generation drive with the performance that matches that title, you want a drive with synchronous flash like the Force GT.
