A base Windows 7 Professional 64-bit install is used for the operating system.  Non-essential services including Fax, Firewall, System Restore, Windows Defender, Windows Search, Windows Update were disabled, as they can affect testing results.

All tests were performed 5 times each, and the average of all test runs were used as the results.  Between each test run, each SSD had the ATA Secure Erase command executed on it using Parted Magic to restore performance.

The SSDs were connected to the SATA 6G connectors on the test bed's Z68 based motherboard.  Intel's Rapid Storage Technology AHCI driver was used.
