Is Firebird 2.1 efficient to store a massive number of rows in some DB's table?

Question

My application keeps receiving a really small event that it needs to store and I was thinking which is the best way to handle it. The table for this event would be something like this:

EVENT
id
timestamp
some_data (integer)
fk_to_some_holder_table

If I keep storing each event as a row, will there be some disadvantage against an implementation with some kind of blob compression/treatment? Or am I going too far here?

I'm using Firebird 2.1. If needed, I could upgrade to Firebird 2.5.

Thanks in advance.
