Controller and Cache Factors

There are a few performance factors that are related to the hard disk's integrated controller, and its internal buffer. Since these parts of the hard disk aren't typically the most important in terms of their influence on overall performance, this discussion is relatively brief. However, these components do have an impact on performance. I also want to point out that some of the aspects of how the cache functions are more important than just its size, which it sometimes seems is all that most people focus on today...
