Crysis 2 only requires 9 GB of free space to install. That’s less than the original Crysis (12 GB). But only a small portion of that data is used to launch the game. According to the summary stats, the exact figure is a little over 300 megabytes consisting of pure reads.
Interestingly, the I/O involved in loading Crysis 2 is far less intensive than you might think. Almost all of the accesses are sequentially organized and 4 KB in size at a queue depth of one. There would theoretically be very little difference between SSDs and hard drives here because transfer sizes are still the bottleneck in a sequential access pattern.
- 94% of all operations occur at a queue depth of one
- 79% of all operations are sequential
- 76% of all operations are 4 KB in transfer size
