QNAP TS-253B Review (Page 7 of 8)

Page 7 - Performance and Power Consumption

For our tests, the QNAP TS-253B was connected to our central home network with CAT5e wiring. One Seagate NAS HDD ST4000VN000 4TB was installed in the TS-253B 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 QNAP TS-253B 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 QNAP TS-253B than the NAS itself. The results were within our expectations, which was excellent. As you can see in our graphs above, the QNAP TS-253B was capable of doing 111.78MB/s for write and 112.55MB/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 118.964MB/s in read and 118.169MB/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 than the AS3202T in write but marginally faster in read; the gap was not considerable in either though. At peak, the TS-253B was limited only by the network interface and not the performance of the NAS itself. The QNAP 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 a reasonable 14W idling and 18W under load. These figures were a bit higher than the ASUSTOR AS6404T and AS3202T on both counts, systems with the same and previous generation Intel Celeron quad core SoC as the TS-253B, respectively, which was surprising. Considering the performance class of this device, this is acceptable, but not impressive. Power consumption will drop if the hard drives are configured to turn off if they are not used or when the QNAP TS-253B is sent into standby mode. Considering it is going to be running 24/7, every watt adds up.
