Hi
John:
I totally agree
with you... RAID 5 is best suited for that purpose.
The only reason we
have it as such is simply because of redundancy. The best for mailboxes is
RAID 0+1. RAID 5 gives us the ease of adding more storage and more
redundancy.
But You are
right..
Regards,
Kami

Hate to differ, but I disagree, as I am sure others will, on using RAID 5 for mail boxes. The mail boxes are heavy Read AND Write. RAID 5 will slow performance in heavy write usage. RAID 5 is best and shines the greatest in mainly Read situations, like databases that use transaction logs to do most of the constant writing. (Where the transaction log sits on RAID 1 or 0+1.)

Mark:
I might have missed it in case you mentioned it.
What is your drive configuration? I believe that also can make a lot of difference.
It is best to have your spool directory separate from your mailboxes. Our configuration is as follows:
1: RAID 0+1: OS & Application 2: RAID 0+1: Spool 3: RAID 5: Mailboxes
I believe performance increase can also be made if the Pagefile is separated and put in its own drive but we do not have it.
I am not sure if in your case it will solve the problem but I have a feeling it can help.
Regards, Kami
