PCMark Vantage - Drives with Data Testing
Version and / or Patch Used: 1.0.0
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.
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.
Despite the A19 advantage until this point, IMFT flash performs better with data on the drives. This is more in line with how people use SSDs rather than how most benchmark them. The smaller capacity drives tend to do better here as well because the flash translation tables are smaller. SSDs are dynamic in many ways, and there are tradeoffs around every corner.
