So RAM would require a little digging to figure out; disk is easier to explain. The disk calculations do not take into account (as best I can tell) the fact that bitcask is an append-only store and requires periodic merging/compaction of the on-disk files. Thus, depending on your merge triggers, more space can be used than is strictly necessary to store the data.
