Will rrdtool be unhappy with a 1.1GB file?

I can spare the disk space, I'd rather log and keep more if it's not going
to cause issues. Is graphing 20 temperatures every minute over 5 years, and then every 5 minutes over 30 years really a bad idea, or on a modern system as long as I have the disk space, who cares?

To answer my own question, cacti and rrdtool seem to be doing fine with a 1.1GB file. Loading 2 months worth of data with rrdtool update took 3 seconds.
