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.
HDD1 - Windows Defender
HDD2 - Gaming
HDD3 - Windows Photo Gallery
HDD4 - Vista Startup
HDD5 - Windows Movie Maker
HDD6 - Windows Media Center
HDD7 - Windows Media Player
HDD8 - Application Loading
This is the best part about what OCZ did with their new beta firmware. Since there aren't many people that test SSDs with data on them this might be a big clue why OCZ sent us this firmware to test with today.
With the initial release firmware and the 1.4RC the drop off was very significant. We've stated for the last year and a half to two years that performance drop off is the next frontier for SSDs. It's easy to get amazing peak performance when an SSD is empty, but when the drive is populated, it is much harder to retain performance. Using the 50% of user capacity mark for our main gauge (blue-green line in the middle) we see that the drip off is less severe with the new beta firmware.
Since you do not use your SSD empty this performance increase is very significant! Much more so than any other test or benchmark we display in our review and preview articles.
