W2K3 20tb directory usage reporting

I have the following phases and need to find the right tools/solutions to get the job done, if anyone has any comments on any aspect please reply

PHASE1
we have a 20tb volume on a W2K3 file server, for phase1 we want to:
* run a utility and dump to CSV file a.) name of folders off root b.) size of folders off root (ex e:\folder1 20gb) c.) the create date timestamp of the folders
* with minimal disk I/O and RAM/CPU hit, this is why I am trying command line utilities
* I have tried size explorer pro (sizeexplorer.com) which is a GUI app and it does exactly what I want but at the cost of heavy disk I/O, albeit it does cut through the 20tb volume fairly quickly, this solution will work but I would rather have a low impact command line tool/script
* command line tools we have tried (du (sysinternals), du (linux), dir command, ls for windows (utools.com), d for windows (glindra.org), diruse.exe (xp support tools)
* with the above tools, I can get the folder path and create time stamp but not size, or, I can get size but not the other
* is there a tool that does it all?
* I have looked at a command line script that includes FOR commands and etc using a directory listing source file but lack the skills to integrate output from multiple commands into one output file
* I am trying to automate the report as much as possible so that we can "spot check" the whole volume from time to time

PHASE2
find a solution that is always running as an agent on the server, collecting and reporting on the directory usage data, albeit with low impact, perhaps reporting to a centralized admin console
* with the size explorer pro (sizeexplorer.com) this is a step in the right direction for an "enterprise solution" I don't know if it can run as a reporting agent in the background or if it is a snapshot in time tool
* ultimately, I want a utillkity that will report by root folder on the volume the following a.) size of folder b.) number of files in a folder c.) time/date stamps of folders d.) type of files in folders e.) support reporting to some level of sophistication
* with this I envision an agent collecting data, with low impact on I/O and and a management console where reports may be run
* I am not familiar with the "enterprise" tools that are on the market, I know there is a Novell product, maybe Crossroads File Migrator or another suite like that
