The QNAP TS-219P is based on the ARM platform: a Marvell 6281 processor at 1.2GHz, 512 megabytes of DDR2 SDRAM, a 16MB flash memory chip (for the bootloader). The main SATA controller is integrated into the processor, the external SATA ports are based on a JMB362 chip. A GL850G USB-hub is also present.
The 6281 model is currently the top representative of Marvell’s Kirkwood series. The chip features a high clock rate, low power consumption (it even lacks a heatsink), integrated SATA ports, Gigabit Ethernet, and USB. This is in fact the top-end all-in-one solution for NASes based on the ARM architecture.
There is a console connector on the PCB but it will only be needed in cases of emergency because the NAS supports standard network access.
Inside the drive there is an iron chassis on which the main PCB, a card with the front indicators and buttons, and a card with SATA connectors for HDDs are fastened. The NAS is cooled by a 70x25mm fan (Y.S.Tech FD127025LB, 12V, 0.09A) with 4-pin connection. With some agility, you can get to it and replace or clean it. The noise level is quite low, so this NAS can be utilized at home without any discomfort.
In the ordinary operation mode the NAS with the test HDDs would consume about 30W. In the sleep mode with the HDDs turned off it consumed a mere 5 watts.
