Any decent modern SQL database system should be able to handle the
data of 100 million "cells". Most databases easily scale up to 1 TB
of data (ie. each cell could well use 10kB data). Beyond that it's
more a matter of the right hardware.

It's generally not a good idea to try to reinvent database technology
from scratch by e.g. using text files. Instead, you should leverage
all the features available in modern databases, such as indexes (of
various kinds), search, transactions, compression, careful caching,
etc. etc.
