Properly indexed, its not that bad...after all its what Dbs do best

I only mention this, that while disk space seems a unlimited resource these days the fact that a DB gets it's bottleneck here is paramount.

I suggest to look up articles about this on www.mysqlperformanceblog.com to find some hints and tips to avoid most of the issues with huge disk space and record access.

And BTW, 'properly indexed' is mostly easier said than done.
