Workaround(s)
Reading from a software RAID-1 partition on Windows leads to the same read performance as reading from a single hard drive.

Like the MD device in Linux, Windows should distribute reads across both drives in a RAID-1 array. Optimally, through clever scheduling read commands could be distributed so as to optimize head movements for both drives similarly to what NCQ does.

Please provide a justification for why you think this new feature should be added to Windows Server 2008.
Because without this, Windows is missing an optimization that could potentially increase read performance by a factor of 2 and which is provided on any Linux-based operating system by default.
