We have multiple terabytes of data in user areas. I don't think you should focus on how much storage - thats up to your company's individual needs. I think that the best practises have automated methods of notifying users when their quota is nearingbeing filled, some have offline storage for stale data(hierarchical storage management).
I think one of the big lessons I have to impart is to think of all your storage holistically. If you put quotas on your email servers and not your network file servers, people will learn to create PST files and save them on the file servers, which defeats the purpose. If you restrict network files servers people will start to keep valuable data on their local hard disk, which inevitably isn't backed up and crashes.
Hope that helps.

James,
Thanks for the prompt reply. We also have multiple terabytes of storage, user, shared, mail, database etc. We are about to implement quotas on mail, but I need best practices on user and shared. We will be using WQuinn's package, with notification and both soft and hard limits. My problem is documenting WHY we selected a given quota... I have to use external references, in addition to our own internal studies, hence the request.

There actually is a process that was handed down to me to determine quotas for users. It's recommended that you dedicate a drive(s) to user space only -no partitions- (except the individual user partitions and operating software)-this way it makes it easier to back up an entire drive as opposed to certain folders in a partition.
1. (and most obvious) How much space do you have? Take that number and divide amongst the number of users for an avg. quota size. (for example here we have 40gb of user space for docs etc. 1000 users 40mb of space.)
2. Look at current use. Sometimes the executive actually ends up using less than the executive secretary.
3. Allow for the big users (some upper level office personnel who are easily using 500mb of space.)
4. Take those cases, subtract them from the total. (So in my case including headroom, and allowing for the large users each AVG. user is 25mb.)
The answer you give then -is an honest one, "..we give you as much space as is available, if you want or need more, we'll have to purchase additional drives"
As to why the big ticket users get more space.. "..their position traditionally requires them to utilize more space. They need it to do their job."
It works for us, I hopthis helps you.
