Testing (continued):

ATTO Disk Benchmark v2.41:

In the last section of performance testing, the network storage devices were mapped to drive letters on the Windows desktop system. I then ran ATTO Disk Benchmark v2.41 to evaluate what it thought of the transfer rates. 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.

At the lower end of the scale that ATTO tests we have 64KB transfers, and the read results are shown below. At just over 118MB/s, the DS1515 in a virtual tie with some of its other DiskStation family of servers, which is definitely fast.



Write results are equally impressive at 64KB, with the DS1515 and DS415+ coming in tied for the best at just over 117MB/s.



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 a very impressive result of just over 117MB/s for the DS1515.



The last set of results to cover are for the write speeds achieved with 8MB files. The DS1515 was the fastest, and provided transfer rates just over 118MB/s.
