we have a Sql 2005 database and we have set the growth of the data file to autogrowth, ‘By 1 MB’
We see that it does that approx every 10 minutes (its 9 GB now).
Is it as simple as: just put it to 10 or 100, or are there other things to consider, or can we just leave it at this because it’s just an easy operation?
Yes, it can be. The speed of your disk subsystem is a factor, but 1MB is a little small. Perhaps 50 – 100MB would be better.
Pre-sizing your data and log files expected size under normal operating conditions is a common DBA task.
