The oft quoted figure for the effect of BES servers on Exchange is that BES will increase the amount of IOPS by almost four times.
RIM's article here seems to confirm this:
"From the baseline, the largest increase occurred with all BlackBerry features (that were benchmarked) enabled. Disk transfers /sec grew from 77.52 to 368.97. Even though there was a 3.76-time increase in disk transfers /sec, this number is well below the maximum capacity that the disk subsystem can handle.
Out of the individual features that were benchmarked, RIM observed that wireless email reconciliation, along with the core BlackBerry features enabled (email, calendar, sent item redirection) caused the largest increase in disk use. Disk transfers /sec grew from 77.52 to 335.82, which was a 3.33-time increase in disk transfers /sec."
That said I have heard people say that with each revision of BES, this figure lowers and lowers until it is practically the same as Outlook.
Can anyone confirm this? Is this in reference to Exchange 2003 only, or more specifically to 2007 and 2010 where IO is handheld much more efficiently by Exchange anyway?

As Knotty mentioned - document is for Exchange 2003. Things have changed on RIM side as well as Exchange side. Actually a lot has changed on Exchange side.
I have blogged about it
Look for the example and see how the numbers have changed in the last few years. Hope it helps.
