What does the 64MB cache do? And how do I know if I need it?

Cache is the amount of data the hard drive can keep readily available similar to how RAM works. The more cache you have the more you can keep available when you need it. retrieving data from cache is much quicker then searching the hard drive for the data. More cache speeds up data retrieval. You don't need more cache unless you want faster data retrieval.
