Launching F1 2011

Exploring SSD Performance In Battlefield 3, F1 2011, And Rift

Even though our F1 2011 installation only monopolizes 12 GiB, launching the game is more storage-intensive than Battlefield 3. Our Vertex 3 has to read about 600 MB to get from the launch button to selecting a Grand Prix race.

Most transfers are 128 KB in size, which makes sense considering that a majority of accesses are sequential. Only 21% of the process is random. This reflects the structure of the Steam-based F1 2011 installation. There aren't many files of varying sizes strewn across the drive. Instead, all of the game data is localized to a few large files. However, SSDs excel at speeding up random accesses. As a result, you don’t have queue depths stacking up like you would see on a hard drive.

I/O Trends:

  • 62% of all operations occur at a queue depth of one
  • 36% of all operations occur between queue depths of two and four
  • 79% of all operations are sequential
  • 5% of all operations are 4 KB in transfer size
  • 10% of all operations are 8 KB in transfer size
  • 80% of all operations are 128 KB in transfer size
