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.




Obviously the access times are going to be slower on the 5,400 RPM Caviar Green; that is one of the biggest benefits of raising the platter speed. Platter speeds are one thing, but electronics are another. Even though the Caviar Green is at a platter speed disadvantage, its electronics are able to make up for it. Looking at the average in the test, we see that the Caviar Green accesses data faster than the Barracuda XT.




Write access times these days are all about electronics; the cache is king and even though the Caviar Green has a massive 64MB buffer, the latency from the Highpoint HBA is not allowing the drive to score as well as it could under ideal conditions.
