Testing (continued):

ATTO Disk Benchmark v2.41:

In the final round of performance testing, I mapped the network storage devices to create drive letters for each on the Windows desktop system. I then ran ATTO Disk Benchmark v2.41 to see how each device fared. The test was run in a fairly standard configuration; with a transfer size from 0.5 to 8192KB, a total length of 256MB, and the queue depth at 10. Read and write results are provided in terms of MB/s, and higher is better. A small sampling of the many results provided are shown in the charts below.

At the lower end of the scale in ATTO we have 64KB transfers, and the read results are shown below. The N5550 comes in at just over 104MB/s, which may only be good enough for second place, but definitely impressive.



At close to 116MB/s, the Thecus N5550 is the fastest server on hand when it comes to ATTO's 64KB transfer test for writes.



Moving up to the top of the file transfer sizes used in ATTO's benchmark, we have results for 8192KB (8MB) file transfers. The read results are shown below, where we see a very impressive result of just over 112MB/s for the N5550. The DS415play may take the top honors here, but these two NAS servers are very closely matched.



The final graph covers the write speeds achieved with 8MB files. The Thecus N5550 comes out on top again, and goes out with a bang by topping 117MB/s.
