I am testing using Mapped RAW LUN instead of the MS iSCSI initator for a File Server. I connect a 100GB Volume to a 2k3 R2 server (64 bit) as Virtual and Persistent Independent disk. For some reason trying Physical did not work,.. For a speed test I have been using Robocopy, a 4 GB file from C: (VMFS DS from EQL) to M: (Mapped RAW volume on EQL) Using W2K3 R2 it takes 1:50 @ 2115 MB/min ... Using Windows 7 same method it takes 1:06 @ 3519 MB/min. Is Windows 7 that much quicker?
