Database search, what to choose?

Question

Data processing

There is a sharp question. Due to the lack of knowledge and experience, I came to ask the professionals, do not scold me for stupidity.
essence of the question:
There is data, 10 quadrillion hashes and a number tied to each hash. Whether prompt really to carry out loading of similar base on a database and the subsequent search. That is, I enter a hash into the search, I need an attached number. How much will this weigh and how quickly the search is carried out. Thanks
