For me, simplicity and functionality is the key. For smaller db's, I like every datafile 1G or 2G. Then if I know that roughly every file takes the same time to backup. If I need to swap two for io balancing reasons, then I know space-wise I'll be fine. Any datafile that I drop can easily be replaced with another.

For a big db, some other things come into play - like filesize limits (another reason I like raw), the checkpointing overhead for massive numbers of files, fitting the files onto a tape etc. So in these cases, you might end up with a "funny" standard size, but as long as you are consistent its easy...

I would like to patent this as "locally managed datafiles" :-)
