Database storage in Exchange 2016

Dear Wizards, if we change this setting of Exchange database to 183 days (6 months), how is the consuming speed of database storage?

Can we calculate or anticipate it?

Not Sure about the, which setting you change, is it related to " Retention policy " or Mailbox Box Size

If the Default size of  Mailbox then, then this formula is used for Capacity of User mailbox

Mailbox Size = Mailbox Quota + White Space + (Weekly Incoming Mail × 2)

Mailbox Size
= 2,048 MB + (7.3 MB) + (52 MB × 2)

2,159 MB
= 2,048 MB + 7.3 MB + 104 MB (5 percent larger than the quota)

Know IOPS

To understand the Database is cosumed, it is  important to understand the amount of database I/O per second (IOPS) consumed by each user because it lead to aequately sizing storage.

The two Important factors to predict Exchange 2010 database IOPS are the amount of database cache per user and the number of messages each user sends and receives per day. View the below image details

Not sure that is possible, but since this will affect all your mailboxes on that database and you can't really determine how frequently users are deleting mail content. If you are using this as retention i would suggest using an archive mailbox or something, i would just let the default set to 14 days and that way as exchange clears out the dumpster it can reuse that storage space. As Exchange cleans out the recovery dumpster, it creates the white space but Exchange will reuse that storage space for new mail items. The problem with keeping that for 6 months is that this can definitely fill up your database quicker since exchange keeps this on the DB, but can tell how fast it will grow.
