Page 7 - Performance and Power Consumption
For our tests, the ASUSTOR AS6404T was connected to our central home network with CAT5e wiring. One Seagate NAS HDD ST4000VN000 4TB was installed in the AS6404T for the purpose of benchmarking. The client computer was configured with the following specifications:
CPU: Intel Core i7-4790K @ 4.6GHz
CPU Cooling: Noctua NH-D15S
Motherboard: Gigabyte GA-Z97X-UD3H-BK
RAM: Patriot Viper 3 Low Profile PC3-17000 4x8GB
Graphics: Gigabyte G1 Gaming GeForce GTX 960 4GB
Chassis: Fractal Design Define R5
Storage: OCZ Vector 180 240GB; Crucial MX200 500GB
Power: PC Power & Cooling Silencer Mk III 1200W
Sound: Auzentech X-Fi Bravura
Optical Drive: LiteOn iHAS224-06 24X DVD Writer
Operating System: Microsoft Windows 10 Pro

Equipped with the Seagate NAS HDD ST4000VN000 4TB, our ASUSTOR AS6404T was ready to roll. From our experience in benchmarking, Intel Gigabit LAN adapters -- at least on the client side -- typically perform better than their Realtek and Marvell counterparts. Therefore, to prevent any bottlenecks on the client side, our Gigabyte GA-Z97X-UD3H-BK motherboard was connected to the network via its integrated Intel Gigabit LAN adapter. We also conducted the tests on our OCZ Vector 180 240GB solid state drive on the client side to ensure there is nothing limiting the performance of our ASUSTOR AS6404T than the NAS itself. The results were within our expectations, which was excellent. As you can see in our graphs above, the ASUSTOR AS6404T was capable of doing 108.63MB/s for write and 112.98MB/s for read using the Seagate NAS HDD. At this point, the bandwidth of Gigabit LAN is the limitation.
ATTO disk benchmark provides valuable insight into evaluating disk performance; it is especially valuable since it is not local disk limited like Windows file copy -- but rather the network adapter itself. After first using it in our QNAP TS-559 Pro+ review countless years ago, ATTO has been an integral part of our storage benchmarks; used in everything ranging from USB flash drives to solid state disks. Venturing into the area of 119.040MB/s in read and 118.253MB/s write for pretty much everything 64K and up, remember the theoretical maximum of Gigabit Ethernet is 125MB/s (1000Mbps / 8) with overhead -- this is about as fast as it gets. Under the curve, it was slightly slower to pick up that high power systems like the QNAP TVS-473 and even the company's own low power AS3202T, but the gap was not considerable. At peak, the AS6404T was limited only by the network interface and not the performance of the NAS itself. The ASUSTOR delivered performance well in line with the competition for standard workloads.
With one Seagate NAS hard drive installed, power consumption for our specific configuration was at an excellent 11W idling and 14W under load. These figures are only one watt higher than the ASUSTOR AS3202T on both counts, a NAS with a previous generation Intel Celeron quad core SoC, making it one of the most power efficient systems we have ever tested. Considering the performance class of this device, this is very impressive. Power consumption will drop if the hard drives are configured to turn off if they are not used or when the ASUSTOR AS6404T is sent into standby mode. Considering it is going to be running 24/7 -- unless Wake on WAN is your thing -- every watt will definitely add up.
