Testing (continued):

ATTO Disk Benchmark v2.41:

For the last phase of performance testing, I mapped each of the network storage server's shares to create drive letters on the Windows desktop system. I then ran ATTO Disk Benchmark v2.41 to see how each device fared. 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 W4000+ definitely performs well here and was able to exceed 110MB/s. A handful of other devices are faster, but in my opinion 110MB/s is definitely impressive.



Write testing with 64KB transfers in ATTO shows another round of less than stellar writing results.



Moving to the largest 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 the W4000+ come in just over 114MB/s. That puts it up there with the fastest NAS servers tested and I would be happy to have that kind of speed any day.



The last set of results to cover are for the write speeds achieved with 8MB files. The W4000+ wasn't the fastest, but it was pretty fast at 98MB/s. The strong performance here just adds more confusion to the inconsistent writing performance results achieved.
