Exterior Design and Hardware Configuration

Synology DS413j

This design was first unveiled back in 2006 when Synology released its CubeStation CS-406. The cooling system is the only change since then. It now includes two fans instead of one. The DS413j doesn’t support HDD hot-swapping.

The front panel is made of white glossy plastic. A power button with an integrated indicator is centered on a gray insert in its top half. Above it, there are six more LEDs, indicating system, network and HDD status. Half of the vent holes here do not have any dust filters, so you’ll have to clean the NAS often if you install it in a dusty room. The bottom part of the case is made of plastic while the top and most of the rear panel are silver-painted metal.

There are grids of two 80mm fans in the rear panel. The NAS’s connectors are all at the bottom of it: a power connector, two USB 2.0 ports and one Gigabit Ethernet port. A hidden reset button can also be found here. The NAS measures 17x23x18.5 centimeters and stands on four rubber feet.

To install your HDDs, you unfasten the four screws that secure the rear panel, flip it down and take off the top panel. The HDDs are first secured in plastic frames and then are put into the NAS. The frames are compatible with 3.5-inch as well as 2.5-inch drives.

A backplane is used for connection which is more reliable than the flexible cables employed in early modifications of this case design. The design is quite practical overall except that you have to fasten too many screws. Fortunately, you don’t have to do that often.

Synology’s junior 4-disk NAS is based on the ARM platform but its configuration isn’t weak even by today’s standards. The Marvell 88F6282 processor is clocked at 1.6 GHz. The system memory is represented by 512 megabytes of DDR3 SDRAM. The OS is installed on the HDDs, so the integrated 8MB flash memory chip only stores a bootloader and a firmware installation module. The SoC processor only containing two SATA ports, the DS413j features an additional 4-port Marvell 88SX7042 controller. The Gigabit Ethernet controller is integrated into the CPU, so there is only an auxiliary Marvell 88E1318 chip on the PCB. A GL850G hub is used to increase the number of USB ports.
