24nm Flash SSD Faceoff - SanDisk Extreme Retake and Plextor M3 Pro - PCMark Vantage - Drives with Data Testing

With two new 24nm flash based SSDs in our labs, it was time to put them face to face.

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.

We prefer our own test where data occupies the drive before the benchmark is ran. Since most of us don't run our drives empty this is a much more accurate test of real-world performance. At a 50% fill state the SanDisk Extreme delivers 53,841 Marks, one of the highest scores we've recorded. The Plextor M3 Pro 256GB only scores 44,770.

 

What is interesting is the Plextor M3 Pro is only marginally faster than the base model M3 when both drives are half full.
