Sorting Data

I need help storing some data (temp) for manipulation. The ideal tool is the listbox. But neither it nor the hash table can hold the amount of information required ( < 150 million). I've been using a binary file but I don't think it's a good idea to create so many reads and writes (into the tens of millions) and it's really slow and takes up GBs of space... so this is a big no, no. The same thing would go for SQL.

Does anyone have a solution? I've been thinking about using several hash tables but there might be a easier way instead of constantly checking which hash has the correct value, etc. Any ideas?

Thanks.
