It isn't that simple. MSFT has different recommendation depending on your hardware deployment, your investments, how many mailboxes, etc. etc. etc.
If you are going to deploy 3 million mailboxes and you don't want to do backups, then MSFT recommends you deploy to JBOD with 3 copies on DAG. If you are going to deploy 300 mailboxes and you are OK with doing a weekly backup and can't afford to dedicate multiple servers, then MSFT recommends you deploy to RAID. At least RAID-5, preferably RAID-10. Go to msexchangeteam.com and download the latest mailbox calculator. You might find it to be overly complicated, but it addresses pretty much every scenario. If you want to share more about your target environment, I (or some of the other smart people here) can probably help you more. Regards, Michael B.

How do you value I/O speed, disk failure, redundancy etc etc in your organisation, thats the answer. --James.
