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 access time stays fairly steady but does have a few spots where we found peaks. The JMicron controller does have some of the highest latency on the market when it comes to SSDs, but is much lower than traditional platter based drives.




When it comes to write access times we don't even bother to list the average and maximum on the charts when a JMicron controller is used. The controller is very dependent on the cache module and once it fills up the latency goes sky high.




Here we see the actual benchmark graph that shows latency which on one occasion went all the way up to nearly 5 seconds. This shows that it is possible to overload the cache with large data writes and that in some rare cases you may run across studdering. Getting to that point would be difficult in real world conditions, but it is possible.
