Everest Ultimate and Corporate Edition offer several different benchmarks for testing and optimizing your system or network. The Random Access test is one of very few if not only that will measure hard drives random access times in hundredths of milliseconds as oppose to tens of milliseconds.

Drives with only one or two tests displayed in write the write test mean that they have failed the test and their Maximum and possibly their Average Scores were very high after the cached fills. This usually happens only with controllers manufactured by JMicron.


Read Tests

SSD manufacturers always get a big kick out of seeing their access times compared to platter drives. Here we see the fastest consumer platter drive on the market and the only 10K RPM consumer series, the Western Digital VelociRaptor. The 10K RPM part is a bit important since it is what gives the VR such low access times for a platter drive.

Aside from the serious ass kicking we see the Vertex 2 drives dishing out here, we are trying to focus our attention elsewhere. Notice the scaling that happens when looking at the chart from bottom to top. Here we see read access times cut nearly in half from the smallest to the largest in the test. The two middle drives offer us perfect markers in between even though the 100 and 120GB drives are physically identical.


Write Tests

The write access test shows nearly identical performance for the Vertex 2 drives.

If you were wondering why I don't like including platter drives in my SSD performance charts, this is why. The platter drives really minimize the differences between the SSDs. Then again, we are measuring SSDs in thousands of a second; how much more minimal can it really get?
