Page 10 - NAS Performance, Power Consumption
For our network attached storage tests, I used an ASUSTOR AS3202T hooked up using an array of CAT5e cables and a Gigabit switch. The AS3202T is one of the fastest NAS we have tested here at APH Networks for linear read/write performance. 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 R6 Blackout TG
Storage: OCZ Vector 180 240GB; Crucial MX200 500GB
Power: Seasonic PRIME Ultra Titanium 850W
Sound: Auzentech X-Fi HomeTheater HD
Optical Drive: LiteOn iHAS224-06 24X DVD Writer
Operating System: Microsoft Windows 10 Pro
Loaded with different hard disk drives, our ASUSTOR AS3202T was ready to roll. 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 above test on our OCZ Vector 180 240GB solid state drive on the client side to ensure there was nothing limiting the performance of our ASUSTOR AS3202T than the NAS itself. In both the read and write test, all tested HDDs came to a statistical tie, as we have saturated the bandwidth limit of the Gigabit Ethernet interface.
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 back in 2010, ATTO has been an integral part of our storage benchmarks; used in everything ranging from USB flash drives to solid state disks. Venturing in the area of 118MB/s in write and 113MB/s in read for pretty much everything 32K and up, remember that the theoretical maximum of Gigabit Ethernet is 'only' 125MB/s (1000Mbps / 8) with overhead -- this is about as good as it gets. The IronWolf Pro 14TB's ramp up profile was very similar to the 12TB IronWolf Pro in both read and write.
With one hard drive installed, our ASUSTOR AS3202T consumed a moderate amount of power with one Seagate IronWolf Pro ST14000NE0008 14TB hard drive. Thanks to the helium fill as discussed in Page 2 of this review, the ST14000NE0008 14TB was very efficient especially considering its capacity. As most network attached storage systems will be running 24/7, and there will more than likely be multiple hard drives installed, every watt will definitely add up on your power bill. When idling, the entire system equipped with the 7,200RPM IronWolf 14TB took only 11W; one more than the 5,900RPM NAS HDD 4TB and the same as the helium filled IronWolf Pro 12TB. This is a whopping 2W difference for just one drive alone compared to the 8TB NAS HDD. The gap continued into our load tests. The system equipped with the Seagate IronWolf Pro 14TB came in at 14W; same as the 12TB variant and just one more watt than the 5,400RPM Western Digital Red 10TB and Seagate IronWolf 10TB.
