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.
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.
If you've been following this new test over the last couple of weeks you'll see that it now has a new scoring format. Perfect results will have each group of numbers for a product staying equal all the way through. Poor results will have a sideways V shape. Really poor results will start out high and never recover.
The Corsair Performance 3 played a large role in the making of this test. The P3 is able to achieve nearly the same performance no matter how full the drive is and thus has a fairly flat performance graph vertically. Aside from the performance when the drive is full, the Performance 3 doesn't rely on TRIM as heavily as many other drives on the market.
Since RAID arrays are not able to receive TRIM commands it is important for a drive to clean itself at all times. The Performance 3 is the only drive we've tested to date that is able to take care of itself in this way. To put it simply, the Corsair Performance 3 is the best drive you can use for a RAID array today.
