I am working on a system that store file hashes and a corresponding description
basically, the structure is very simple just 1 table, HASH (key) and File Description.
For example:
8F28067D10C64952F79542BF1EE349CB | Windows XP beckgrounf picture
The hash, of course, is also the unique key.
Assuming that this table is going to be huge and that search from the DB should be as quick as possible (by the hash at least)
What will be the best database to use in this case?
