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've been slowly retesting our stable of archived drives, but I haven't finished the RAID drives yet. The Fill Test was actually developed to showcase the Corsair Performance 3, a drive that doesn't lose performance when data populates the drive. Here we see that the Patriot Wildfire RAID 0 array doesn't lose much performance either, even when filled to 75% capacity.


On the other hand, though, the Dirty / Empty test does give us something to be concerned about. Without TRIM, your RAID array will need time to cycle garbage collection. Here we see the array going from peak performance (71,251 Marks) to a degraded performance state (65,895). The chart pattern does show that performance was quickly retained after data was deleted.


These tests are ran back-to-back, so there isn't much time for the drives to work cleanup. After a couple of hours, performance should be back to peak.
