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.

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.


As we've stated before, regular consumer workloads are not that impressive on many RAID array systems. You need to be able to tune the array for low queue depth performance, but the RevoDrive 350 doesn't include any knobs to turn for the settings. The drive does offer enough performance to have a comfortable experience while doing regular day-to-day activities and has performance in reserve for demanding workloads.

Here we see that with half of the drive full and under a consumer workload, the RevoDrive 350 settles in with many of the 2.5-inch drives performance wise.
