Server 2012 vs. Server 2012 R2 NAS Performance

The purpose of this review is to compare the NAS performance of Windows Server 2012 vs. Server 2012 R2. The comparison test was performed between 8 client machines running the Windows 10 operating system and two identical quad-core servers with the first one running the Server 2012 operating system and the second one running the Server 2012 R2 operating system. The client machines and both NAS servers were equipped with identical Crucial MX300 1TB SSD drives. An identical data set containing 30,000 small and medium-sized files was copied between the client machines and both of the NAS servers using the DiskBoss data management utility, which is capable of transferring data using multiple parallel data streams.
