Our Test Methodologies: Under each test condition, the Solid State Drives tested here were installed as secondary volumes in our testbed, with a standard spinning hard disk for the OS and benchmark installations. The SSDs were left blank without partitions wherever possible, unless a test required them to be partitioned and formatted, as was the case with our ATTO benchmark tests. And all drives were secure erased prior to the start of the 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.

In the following tables, we're showing two sets of access patterns with IOMeter; one with an 8K transfer size, 80% reads (20% writes) and 80% random (20% sequential) access and one with IOMeter's default access pattern of 2K transfers, 67% reads and 100% random access.
IOMeter had the new WD SiliconEdge Blue SSD trailing the rest of the pack across the board. In both the default access pattern and our custom workstation pattern, the SiliconEdge Blue just missed the mark set by the OCZ Vertex 120GB in almost every category except for maximum response time, where the WD drive trailed significantly.
