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.
SiSoft SANDRA physical disk benchmark has all of the SandForce based drives performing at near identical levels, with only a few MB/s separating the drives. The JMicron based Patriot Zephyr, however, trailed the others by about 9% in the read badwidth test.
SANDRA's physical disk write performance test tells a similar story. The SandForce based drives are all tightly grouped, once again, and the drives hold onto a significant lead over the JMicron based Patriot Zephyr.
Interestingly, the updated 120GB variants from OCZ and Corsair exhibit significantly lower write performance accorging to SANDRA.
