I covered this recently in pretty good detail on my blog and in EMO. Start here:
http://theessentialexchange.com/blogs/michael/archive/2008/09/19/it-s-all-about-the-iops-silly.aspx I’ve got a half-chapter on this topic in my upcoming book, because it’s something that confuses far too many people. There I include examples calculating the numbers of disks required for small, medium, and large organizations; how RAID-1 and RAID-5 affect those IOPS calculations, and whether you actually need more than one disk (if not for RAID). And, of course, how you properly monitor for all of this. Regards, Michael B.

You're still doing read|write with a single drives heads no matter how you split it up. John W. Cook Systems Administrator Partnership For Strong Families Painfully sent to you from my Blackberry _____ From: Bill Lambert To: NT System Admin Issues Sent: Tue Oct 28 15:56:54 2008 Subject: Basic Drive Partition Question We’ve been arguing here…and I can’t find anything definitive on Google… Is there any gain in performance if you have a single (NTFS) drive in two partitions? One partition for the OS and the other for everything else? I say no but it wouldn’t be the first time I’ve been wrong.
