There are databases of several GB that people use daily.
There is currently a theoretical limit of 2^24 (approx 16,000,000) objects per
class, and 256 main classes (i.e. not counting subclasses). We are thinking
about ways one day in the future to remove those limits, but in practice they
have never approached being a problem. You can certainly live with several
million objects on a reasonable computer. As Ed says, the total disk usage
possible is very large (possibly 1k x 2^32 = 4 TB because blocks are determined
by a 32bit integer now).
