Dear All,

Can someone please advice which option is better on database growth settings on database which is more than 150 GB? either 10% ( by default) or fixed size.

If it's fixed size, how I can forecast the size to fix?

Thanks in advance.

Regards,
Ravichandra.

Don't use percent growth. 10% of 150 GB is 15 GB.
While the database grows by 15 GB, performance degrades awfully.
Use fixed size instead.
I usually set data file growth to 100 Mb and log file growth to 50 Mb.

Like everything that has to do with SQL and configuration, the answer depends.

If you have a large database, say 10GB, then adding 10% growth would consume an additional 1GB of space, this is difficult to swallow if you have limited drive resources. However, if you find that the database is growing and requesting additional drive space on a daily basis, maybe you should change the auto-growth to 15-20% each time.

The best design is the one where you anticipated the database size from the initial installation and allocated drive space accordingly, however, without years of tracking growth, it is virtually impossible to get this number right from the beginning.

So, it comes down to resources and the current size of the database.
