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.

One way for SSD manufacturers to separate one product from another is to build a drive that works well, even when data populates the flash. We use the 50% of capacity market to judge performance in a used state. The Samsung 840 EVO mSATA is the new king of mSATA drives when it comes to performance with data on the drive. This used to be a low point for older Samsung SSDs, but Samsung has managed to build new products that put the company's drives in a leadership position.
