I had a drive connected to a Windows Server 2008 R2 VM, moving ~1TB data around when it was connected locally to that VM was instantaneous. I disconnected that drive and connected it to a Server 2012 R2 server and am connecting to it from the Server 2008 R2 server as a network drive. Now when moving ~1TB data around on the same drive, it takes significantly longer. Data is being moved around on the same drive but it's taking longer than before, the drive was previously local to the Windows OS, but it's now a network share. Is this typical?
