How a NAS performs can be somewhat ambiguous; in reality I've been discussing how the N4560 performs in many subjective aspects so far. To test the technical, objective performance we benchmark against other storage solutions we've reviewed. This is a combination of Intel's NAS Performance Toolkit suite which simulates many uses such as HD video playback, file transfer, and office productivity. In our test environment, we built three RAID configurations (JBOD, 0, and 5) between three physical disks and tested each with the following results:
The best comparison in this situation would be with the N5550, which was tested with the exact same discs as the N4560. The results ebb and flow in favor of one or the other in different categories, but taken on the whole they hit pretty close to the same mark as what we would expect.
