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 is a test run just after the fill tests, and shows if a drive needs time to recover, or if performance is instantly restored.
We like the Vantage test, but we like our version a bit better. Using the 50% of total NAND capacity as our benchmark, the ASUS ROG RAIDR Express 240GB compares well to the other drives. If the RAIDR were the fastest drive in this test, we'd be impressed, but some of the other drives are faster.
