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.

Before we get started we need to point out that the SanDisk Extreme currently has an issue with TRIM. With a fresh drive the Extreme produces a score of around 86K Marks. We decided to show the Extreme under the same 'dirty' state as the other drives. When SanDisk releases a firmware update that fixes the TRIM issue, we'll re-test and update the numbers on our charts.
In the drives with data test we like to use the 50% mark (blue chart line). This is a PCMark Vantage test with the drive half empty or half full however you want to look at it. At this state the Slim scores nearly 46K. This is a bit faster than the Plextor M3 Pro, but a little lower than the Intel 520 Series 240GB and the SanDisk Extreme 240GB drives.
