Loading Levels In Battlefield 3
Loading a level is actually more storage-intensive than launching the game. This makes sense, of course, since you aren't loading a lot of data until you choose a level and start loading it into memory.

When we load the Thunder Run campaign, our Vertex 3 reads more than one-third of a gigabyte. Almost all of the operations are sequential in nature, but the largest cluster consists of 128 KB chunks of information. With that said, smaller transfer sizes also constitute a notable portion of the loading sequence. Our obvious prediction here is that you'll also realize measurable gains loading a level in Battlefield 3 from an SSD compared to a hard drive.
