My first thought is that bonnie++ does some of this.
http://www.coker.com.au/bonnie++/

What it doesn't do is check on accuracy, but it wouldn't be too
horrendously difficult to add that as a feature, especially
since that's something that Coker wrote in Postal/Rabid, his
mail system performance tester. (You might even suggest it as a
useful enhancement for bonnie++ 2.0.)

If you end up scripting it, I think bonnie++ runs alternating
with AIDE ( http://sourceforge.net/projects/aide/ ) runs will do
most of what you want.
