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.




I'm not ready to call it just yet, but the Data on Disk testing shows 840 Pro 512GB kicking every other large capacity drive on our list's butt. This is the same reason we chose the 840 Pro over Vector in the 256GB capacity size. Both products are very good, but we're here to find the best. I think we just found it.
