Test System, SANDRA Disk and File System Benchmarks
Our Test Methodologies:Under each test condition, the SSDs tested here were installed as secondary volumes in our testbed, with a dedicated disk for the OS and benchmark software installations. The drives were left blank without partitions where necessary, unless a test required them to be partitioned and formatted, as was the case with our ATTO and CrystalDiskMark benchmark tests. Windows firewall, automatic updates, and screen savers were all disabled before testing. In all test runs, we rebooted the system and waited several minutes for drive activity to settle before invoking a test.
We should also underscore the fact that the other PCI Express SSDs we're comparing the Intel SSD 750 to here are admittedly very stiff competition and in many cases cost literally thousands of dollars more than the consumer-enthusiast and workstation-targeted SSD 750 line. Rather than comparing the new Intel PCIe SSD to a stable of standard SATA SSDs, however, we felt it made more sense to compare it to other PCI Express SSDs on the market that are in its performance class.

For our first set of tests, we used SiSoft SANDRA, the the System ANalyzer, Diagnostic and Reporting Assistant. Here, we used the Physical Disk test suite and provided the results from our comparison SSDs. The benchmarks were run without formatting on all drives and read and write performance metrics are detailed below.
SANDRA's File System benchmark exhibits combined Read/Write throughput on blank, formatted volumes and generates an aggregate "score" in overall throughput.
