Introduction

I would like to thank Asustor for supplying the review sample.


The Lockerstor 2 Gen2, or in short AS6702T, is a high-end 2-bay NAS by Asustor featuring an Intel Celeron N5105 CPU, which is more than enough for a NAS running a custom-tailored Linux OS. The AS6702T has some notable features, including a pair of 2.5 Gbit ports, USB 3.2 Gen 2 ports, an HDMI 2.0b port to utilize its 4K transcoding capability fully, and support for up to four M.2 SSDs. It might have only two bays for the traditional SATA drives, but the four M.2 drive slots provide an easy way to upgrade storage with fast NVMe drives. If two SATA disks and four NVMe ones are not enough, you can purchase an expansion unit and increase the drive bays from two to ten.

The quad-core Celeron CPU is supported by 4 GB of RAM, which can be upgraded up to 16 GB should you need more memory. There are two memory slots, so you can install 8 GB DIMMs in each one of them. A 70 mm fan handles cooling, and an IR receiver allows you to use a remote control to easily interact with the NAS. Lastly, the warranty is long enough at three years, given that a NAS is meant to operate around the clock.

The Celeron N5105 CPU is highly efficient, with Asustor claiming up to 21 W during operation and 13.5 W at hibernation. I will verify power consumption with my power analyzer and get readings during various usage scenarios. Power consumption efficiency is essential for a NAS since these machines usually operate continuously and not for specific hours per day.

Specifications

Contents and Bundle

A photo of the product has been put on the face of the box, with several icons showing its significant features.


The protection inside the box is good.


The bundle includes two Ethernet cables, two sets of screws, a quick installation guide, and a power adapter.
The NAS follows Asustor's design lines, which have mostly stayed the same all these years. After all, this is a NAS, so it doesn't have to have a unique exterior design.


There are several LED indicators at the face of the NAS, along with a USB 3.2 Gen 2 port and power and copy buttons.


The rear side of the NAS.


A single USB 3.2 Gen 2 port, two 2.5 GbE ports, and a DC input socket are at the back.


The power specifications label is at the bottom of the NAS.


Removing the trays.


The trays have good build quality and also feature plain locks.


The power adapter's model number is DPS-65VB. It can deliver up to 65 W with 12 V output. It is made by Delta Electronics, one of the best PSU manufacturers.

A Look Inside

You have to deal with several screws to fully tear down the NAS, but the whole procedure is straightforward. To access the M.2 slots is much easier.


The barebone chassis.


The mainboard is small, and a heatsink covers the CPU. There is no active cooling for the latter. Finally, the solder side of the mainboard only has few parts installed. The second, empty, RAM slot is also there.


A 4 GB DDR SO-DIMM is installed into one of the RAM slots.


The mainboard uses a Macronix MX25L12872F flash memory IC.


The battery keeping the mainboard's BIOS settings intact.


The 2.5 Gbit Ethernet controllers are a pair of Realtek RTL8125BG.


The SuperIO IC is an IT8625E.


The board's eMMC is a Samsung KLM8G1GETF with a capacity of 8 GB.


Parts of the mainboard's power phases.


An 24C08 Serial CMOS EEPROM.


The SATA expansion card for the two drives this NAS supports.


The board holding all M.2 slots.


The cooling fan is by Apistek (12 V, 0.6 A). It measures 70 mm across, and its model number is SA74B2H. It uses a double ball-bearing and it is of high quality.
