A Look Inside

It's now time to take apart the NAS for an internal look. Disassembly is straightforward.


The one-piece top and side cover is made out of aluminium, while the front and rear covers are plastic.


The mainboard is small but has all the necessary parts required for a capable NAS. The CPU uses a small heatsink without any active cooling since its TDP is only 10 W.


The RAM is soldered to the mainboard, and there is an empty RAM slot that can be used to upgrade the RAM total. The Intel J3455 CPU supports up to 8 GB of RAM.


A plain USB stick is used as flash memory. It is installed to an internal USB port.


The monitoring IC is an ITE IT8613E.


This battery keeps the BIOS data intact when power is removed.

A Realtek RTL8153B controller is used on the mainboard. This IC has a triple-speed Ethernet transceiver and a USB 3.0 bus controller, as well as embedded memory.

Here is the SATA card to which four hot-swappable HDDs or SSDs can be connected.


The model number of the fans is A8025L12S (80 mm, 12 V, 0.1 A), and they are made by Yeehon International, a brand that is not all that well known. On the fan sticker is the Hong Sheng name, a rather popular fan manufacturer.
