Re: DataArea vs. Tables

My perspective on using data areas is that they should be read mostly / update rarely.

This is key to the idea of using them for configuration options that don't get updated often.

I don't argue with that. It's mostly what I've used them for also.
if you are updating the *DTAARA with (say) current record position in
a massive table (for crash recovery for example) then EVERY record
position gets forced to disk and that slows the job *DRAMTICALLY.
Wouldn't journaling be more appropriate for that kind of functionality anyway?
In the specific case we were READING journals and keeping track of where we were in the Journal with a *DTAARA! In most cases I would agree with you.
