Greetings. We've got an on-premise Exchange 2010 Server with 4 user mailbox databases on one RAID10 volume on our SAN (iSCSI).

We have Enterprise licensing for Exchange archiving.

I'd like to create one or more separate Archive databases.

Question - Which of the following would be the best practice I should follow ?:

1. Create new database(s) on the same RAID10 volume.
2. Create a new RAID 10 volume.
3. Create a new RAID 5 (or 1) volume.

Create a new database for archiving, You can use any RAID but it should require redundancy

For this number of users, you aren't really going to see any performance benefits with using a new array, so if you have the space, just create a new database.
If you weren't using a SAN, and were able to put the archive on to slower, but higher volume storage, then things would be different. It isn't unusual to mix the storage types between SAS for the live data and SATA for archive.

Although Simon is correct on the performance front, you asked for best practice on placement and best practice would be to put the archives on a different RAID volume to the main DB.

Good information.  Thank you.  We have available SAN space, so I did create another RAID 10 for the Archive databases (starting with one).  "Best Practice" answered best by connollyg.
