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 Netgear GS108 switch.

Iometer, a familiar benchmark in our test suite, is an I/O subsystem measurement tool. For the purpose of our NAS testing, we set a queue depth of 16 (outstanding I/Os) and run the following three benchmarks:

  • 64KB transfer, 100% sequential, 100% read
  • 64KB transfer, 100% sequential, 100% write
  • 1MB transfer, 100% sequential, 100% read

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 these traces onto a chosen storage solution 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.
