is it true that RAID is no more necessary if you implement Exchange 2010 and DAG

Hi to all of you,
according to several articles, It looks like Exchange 2010 is no hardware demanding in terms of disk IO .
I read that even sata disks are acceptable with no raid (http://blogs.technet.com/ucedsg/archive/2009/05/12/exchange-2010-and-high-availability-part-i-dag.aspx)
Could you please tell me if this is true? how did you configured your Exchange servers with DAG in terms of disk partitioning?
My idea is to place one Exchange on a SAN as virtual machine and a second Exchange outside the san hp proliant with 16 gb ram and sas jbod og 4 tera.
we have 350 mailboxes and the maximum mailbox size will be 2Gb.

thank you for your help

The whole concept of exchange 2010 is that it was built for "cheap and disposable hardware"

I/O was reduced up to 70% from 2007 (which was 70% off 2003)

So you can now be running on 7.2k sata disks with virtually no performance issues.

the partitioning best practices are also have the DB and its log file on the same disk and have one disk for each DB

Hope it helps

according to this post, it still reccomends to place logs and db on different LUNs ... and in my opinion with different raids
