My server has a large amount of memory. However, the amount of IO (each of which is small) is very high.

Is there a way to make a virtual drive out of portion of the memory?

I realize I can also use SSD, but those are expensive.

I need both speed and size. So memory only won't work. Data not often accessed should be in hdisk.

clarification and grammar
