For our next 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 and read and write performance metrics are detailed below. We have also included SANDRA's detailed graph so you are able to see how the drive performs over time along with the average rated result.

The new WD SiliconEdge Blue drive trailed all of the other drives in read bandwidth according SANDRA's physical disk benchmark. It was only a few MB/s behind the Vertex and X25-M but about 10% slower than the C300, when the latter is connected via a SATA 3G interface.

Western Digital's new SiliconEdge Blue SSD outpaced Intel's X25-M in SANDRA's sequential write test by about 50%, but trailed the rest of the pack. At about 158MB/s, the WD drive was about 38MB/s behind the Vertex and 50MB/s behind the C300.
