THE SILENTNAS HS-251 INTERIOR

The board is also identical to that of the HS-210 something which i personally didn't expect.

Apacer is once again the supplier for the 512MB flash memory DOM.

SKhynix Double Data Rate III (DDR3L) Synchronous DRAM modules are present on the board (adding up to 2GB).

The asmedia ASM1074 USB 3.0 HUB Controller is responsible for the USB 3.0 ports of the device and the ASM1442 high speed TMDS level shift IC is responsible for the HDMI ports. Unfortunately since the board got stuck we were unable to turn it over to take a look at the CPU (didn’t want to risk damaging it).

As usual for this test we used two enterprise grade Seagate Constellation ES.3 4TB drives but it's worth mentioning that the recommended WD Red drives are more suitable for 24/7 operation due to their reduced temperature levels and power consumption (our tests however focus mostly on performance).

We also wanted to mention that the tiny remote control which QNAP sells separately worked like a charm throughout our tests so if you're looking for an easy way to control the HS-251 this is for you.
