Other than I/O load balancing.. I can't see any other reason.

But again, why those tiny 50MB files?
Are these on the same disk? I hope not..

If there is no I/O bottleneck issues, I would build just one 700MB file. And then monitor how it works out..

OK, I know we had the debate already but lets have another go at it.

Say you got a tablespace, lets call it RBS and its for rollbacks. Now, for what reason would you create a 500M file and 4 50M files for this puppy as opposed to just one file. I just cannot see the reasoning for this at all. None. Natta. Zilch.

So educate me please if someone out there knows a legit reason they would do this.

Lets assume for the sake of argument that disk size and mount point size is not a limitation. Space available to me on any one mount point is unlimited.
