When you're firing up Crysis 2 and loading a level, you're almost exclusively reading data from your drive. Actually playing the game changes this, demonstrating to us an almost all-write environment. Why is this? Once the game and level data are loaded into memory, the system writes a lot of unique data in order to record progress.

Just as interestingly, most operations occur between a queue depth of two and eight. Everyone's style of play differs, but the way we crept through this level was slow-paced stalker-style. If you're the run-and-gun sort, almost none of your accesses will happen at a queue depth of one, since the game is forced to address more commands concurrently.

I/O Trends:

  • 72% of all operations are 128 KB in transfer size
  • 91% of all operations are sequential
  • 35% of all operations occur at a queue depth of one
  • 60% of all operations occur between a queue depth of two and eight
