How much storage space is right?

There's lots of them out there, but they cost from between $100 - $12,500 for case studies on this.

This site has a few free ones (without the $ sign in front of the article):

Dear Anna777:
Thank you for the extensive list of links. I will study them and check if they answer my question. It will take a few days ...

I just lost my previous effort to answer your question. I will be more precise this time and have it backed up.

You will not likely find a White Paper that will tell you exactly what you will need for specific systems. Each brand of system will have different requirements for storage.

The general rule I would follow is to at least double the installed software's size at first. If the vendor provides a demo you should look at the diffence between a fresh clean install and the demo. This would give you some general information on transaction size.

To get the transaction sizes it is easier to look at your daily volume and average it over a few weeks. This will give you a good idea of growth for your particular situation.

Most vendors will give you storage requirements based on the size of your business etc. Even these will not be exact but you will at least be able to get an idea.

For e-mail you will have to determine first how many users (accounts) will be needed. I think50mb per user is a good place to start but depending on the system you use, it could go much lower.

Go here to look at the 498 papers on Storage Management that I found:

(if the link doesn'twork just use the url to itpapers.com and navigate to Storage under Hardware and then to Storage Management)

This is a hard question to answer. It depends. The amount of disk space you need on a particular computer depends on several factors: What will the computer will be doing. A server or stand-alone? How many users are there? As a rule, the more users you have the more disk space you'll need.
