I would put the file growth of your data file a bit higher than 5MB.

Say you reach the limit of the database file but it doesn't have to grow yet.

The next day you want to add 1GB of data. If you grow per 5MB, the data file has to grow 200 times to be able to include the new data. This will slow down the data load. And this will happen every day after the limit has been reached.

First find out from where data is comming? Depend on the application and design it could be possible to grow data 1GB/DAY. Also find out what kind of data is inserting which will help you to define purge or archive policy. Purge or archive might help you to keep check on your data growth. Also if that is the case you need to plan for disk space required in near future. Does your backup too increased by 1 GB?

This database there is no data retention period also management not accepted to delete old data for identified block listing people.

Data format is storing binary and encrypt format for Photo identification details. Only one Image table have occupied 530 GB.

Already configured on each table for capture data growth on daily basis with history data. In that table size also increased 1GB on daily basis.

Can you suggestion me? Data growth setting can be changed to GB size, so that data file to avoid the growth increment.

If your datagrowth is 1 GB/Day; I suggest to set FILE GROWTH by 5/10 GB. Also think about storage too.
