Playing a game is almost purely write-oriented because its progress has to be updated continually to a temporary location on the drive. Civilization V follows that trend to some degree, but it does so using fewer write operations than Crysis 2 (and more than World of Warcraft).

Most of the write operations are 128 KB sequential transfers at a queue depth of one. There are a fair number of higher-depth transfers, but they are all evenly distributed between two and eight.

I/O Trends:

  • 85% of all operations are sequential
  • 49% of all operations occur at a queue depth of one
  • 46% of all operations occur between queue depths of two and eight
  • 53% 128 KB, 30% 4 KB
