With the Thecus N4100PRO hooked up to my D-Link DGS-2205 5 port Gigabit switch, I first ran Crystal Disk Mark 2.2.
ATTO has been around for some time, but it is still a very popular hard disk benchmarking tool that offers nice features to benchmark RAID setups. The first benchmark that I ran was the one called ‘I/O Comparison’, which is where the benchmark writes files on the disk being tested and then reads them back.
The second test I ran with ATTO is called “Overlapped I/O,” which is where the benchmark performs the same task as in the comparison test, but allows the tasks to be divided and executed in parallel.
As you can see, the performance numbers between the benchmarks differ, which is why more than one benchmarking utility is needed when looking at hard disk performance. Let’s take a look at how the Thecus N5200 does when using an FTP client in a real world test.
