Projecting disk space usage

orh

If the disk usage has gotten to 80GB with 8 years of 1,000 employees.

Would it be correct to say that to add 6,000 more employees, while at the same time recording payroll history of the past 8 years, one would do the following multiplication:

80GB * 7 = 560GB of disk space used after addition ??

I am needing to forecast the disk usage prior to converting and bringing the 6,000 wmployees into the Navision payroll system.

Any ideas? From what I have read from some users, it would seem that there may be too many indexes against the payroll database.

Thanks

Your calculation will be correct if the added users will have the same data-usage as the existing 1000.
I would calculate 10Mb per employee per year. So adding 6000 more employees will not add 10Gb per year, but 70Gb per year.
