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.
The results are not as dramatic as I expected, but this is a good thing for users. As you can see, SSDs in RAID do not gain access time like traditional hard drives. For traditional drives, the trade off of access time for sustained speed can be a problem; the more drives you add, the longer it takes for the platters to get to the data. Once they are there, the transfer speeds are very fast, but adding a couple of milliseconds can make the system seem slower. Solid-State Drives are immune to these effects.
We did notice that access time is lower on the NVIDIA controller since it is tied into the MCP directly, while the Areca controller has a .2 ms delay in sending the data to the same MCP.
