Benchmark System And Power Consumption

Synology DS412+ And Thecus N4800: Two NAS Devices With Atom D2700
By

We maintained each of the servers' default settings and set the maximum transmission unit (MTU) to 1500. We used four Samsung Spinpoint HD103SJs in each NAS device. The N4800’s firmware was version V2.01.05, and the DiskStation DS412+’s was version 4.0-2219. All of the details are in the following table.

Intel NAS Performance Toolkit

We benchmarked the two NAS servers with Intel's NAS Performance Toolkit. A detailed description can be found in Benchmarking With Intel's NAS Toolkit.

Noise

Thecus's N4800 and Synology's DiskStation DS412+ are quiet. During normal operation, the N4800 produces 29.6 db(A), and the Synology DiskStation DS412+ produces 30.2 db(A). Our subjective impressions went the other way; Thecus' NAS seemed louder due to the tone of the sound, bothering us more.

Power Consumption

Our power consumption benchmarks are mixed. The N4800’s power supply unit seems to be more efficient, drawing 1.9 W when the system is turned off. Synology’s DiskStation DS412+ draws 3.3 W.

This trend reverses once the NAS servers are on, writing to all drives (a workload encountered during a RAID rebuild). The Synology DiskStation DS412+ draws 48.2 W, which is less than the N4800’s 54.0 W.
