Notes

All of our comparison NAS servers are tested using a single Gigabit Ethernet link with jumbo frames disabled, and are connected to our Intel client machine and network via a TP-Link TL-SG1024 switch.

Taking a look at a basic usage scenario, our file copy test involves moving a mixed assortment of files totalling 8.83GB in size from our client to the NAS. The result is recorded in MB/s.

Our second benchmark - the NAS Performance Toolkit, developed by Intel - is a file-system exerciser specifically designed to provide performance comparisons between NAS devices. Intel's utility focuses on user-level performance using real-world workload traces gathered from typical digital home applications such as HD video playback and record. Intel NASPT reproduces the file-system traffic observed in various traces onto a chosen storage device and records performance in MB/s.

Last but not least, we measure NAS power draw during three states; under load, idle and standby mode if applicable.
