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.

Filling the drives with controlled data gives us a look at consumer steady state performance. SSDs slow when they have data on the flash, but some flash and some controllers do better than others.

 

The Toshiba Toggle in the Kingston V300 does better than the Intel 20nm here. TRIM seems to work better with Toshiba 19nm as well.
