There is a lot of talk about the performance improvements in Exchange 2010- in particular the reduction in Disk I/O.
Is this real or imagined? What are the tradeoffs Microsoft has had to make in order to make this work?
Join Exchange Expert and Mimecaster Barry Gill talk through some of the issues when looking to design your Exchange 2010 environment to take advantage of the improved performance.

Justin Pirie (JP): So we’re back with Barry Gill, welcome to the Mimecast video blog. So, I’ve been hearing a lot of talk about the performance improvements in Exchange 2010, can you talk me through some of those please?
Barry Gill (BG): Well certainly Justin, I think one of the most significant performance that Exchange 2010 has introduced to us is the 70 to 75 percent input output or I/O performance improvement.
JP: So that’s disks isn’t it.
BG: That’s disk, yeah. Now what Microsoft have done is something they’ve been trying to get rid of since essentially Exchange 2000, is they’ve gotten rid of Single Instance Storage, so no longer are read and write operations are being scattered across platters on a disk, they are now, all of these processes are happening sequentially. So sequentially means there’s a lot less distance for the heads to travel across the drives which means they’re able to get these massive performance improvements.
