Hi, guys.
Welcome back to ChargerLAB.
We recently got a huge brick from Seagate,
the Seagate Firecuda Gaming Dock with 4TB External Hard Drive.
It has five USB-A and two Thunderbolt 3 ports.
Except for the ports.
It also has 4TB storage.
You csn enjoy the large storage and high speed at the same time.
Let’s teardown it directly to see what is inside.
Firstly, The appearance.
The overall shape of the product is square, like a giant brick.
An air vent is on the side.
And there are more ports on the back.
From left to right, we can see the power port.
Two Thunderbolt 3 ports.
One DisplayPort.
Three USB 3.0 ports One Gigabit Ethernet port.
Turn to front side.
We can see the power button.
Two USB 3.0 ports.
Headphone jack and audio interface.
There are four rubber pads on the bottom and an air inlet.
Take a look at the specification.
Rated power is 20V 5.5A.
And it can connect external power supply instead of consuming the computer’s power.
Open it.
There is an M.2 NVMe slot inside
You can install SSD by yourself and transfer data through Thunderbolt 3.
There’re three metal contacts on the side, used to drive LED.
And you can see a fan inside through the air vents.
You can use it to connect external monitors, hard drives, ethernet cable, and power other devices,
which is very powerful.
It’s very suitable for products that rely on dock, like MacBook or iMac.
After introducing this product.
Let’s start to tear it down.
Start from the middle part and remove the screws on both sides to open the top cover.
There are thermal pads on the top and bottom of the slot for heat dissipation.
This small PCB is fixed with screws.
Tear off the rubber pad at the bottom, And remove all screws underneath.
Finally, open the top case.
The internal 4TB HDD occupies most of the space.
The small board of SSD is connected to PCB of the top cover.
There are another connectors, used to connect the main PCB.
The PCB of the top cover is covered with a plastic light guide plate.
Remove the light guide plate.
There is a chip on the left.
And some LED lights are on edge.
This is LED light driver from Texas Instruments LP5036, used to control the light effect of LED.
There are three metal contacts on both sides on the back of the PCB, used for power supply
and communication.
There is a cooling fan on the front of the HDD.
Its wire adopts plug-in design, easy to remove.
Here is a PCB, used to connect HDD and the main PCB.
There are two screws on the side of the HDD for fixing.
The main PCB is under the HDD.
Here are two screws on the other side of the HDD for fixing.
Remove all the screws and we can see there is a metal plate at the bottom.
There are lots of holes in the center of the plate.
There are hollow between the HDD and the main PCB.
The heat generated by the HDD and main PCB will be dissipated through the cooling fan.
The HDD is connected to this PCB.
There are four electrolytic capacitors and shielding cover on the front.
The specifications of those capacitors are 100μF 16V.
There are two triodes inside after removing the shielding cover.
The bottom plate is made of metal, which can enhance heat dissipation.
A plastic insulating plate is attached to the right end of the PCB’s back.
There are almost no components on the back of the PCB.
But there are lots of holes on the front, used to strengthen the heat dissipation.
Remove the plastic insulating plate.
This is the network interface controller from Realtek RTL8153.
The power port is reinforced with metal shell, marked with Foxconn.
The specification of two electrolytic capacitors is 100μF 16V.
Here is the thunderbolt 3 Controller from Intel JHL7440, which supports two PCIe Gen3x4
and DP1.4 and is compatible with USB-C.
This chip is used for the lighting control, which comes from NXP LPC11U67J.
The cooling fan comes from sunon, which needs 12V power supply and supports speed measurement.
The Dual USB-C port controller comes from Cypress.
Both USB-C receptacle ports are covered with conductive fabric.
There is a button in the middle, used for firmware upgrade.
Here is high-precision adjustable current limit switch, which comes from TI TPS2553
and is used for current limit protection of USB port.
The memory adopts MXIC MX25V2035F.
The three chips of USB 3.1 Gen2 hub adopt VIA Labs VL822-Q7, used to connect peripherals,
such as external network cards and audio codecs.
This is limit switch of 1A current load,
which comes from Diodes AP2171 and is used for overcurrent protection of USB port.
The converter of USB3.1 to SATA6G adopts Asmedia ASM235CM for data transfer between HDD and SSD.
This is high-precision adjustable current limit switch, which comes from Texas Instruments
TPS2557.
This is Texas Instruments PCM2912A, which
is an audio codec with a USB interface for a USB headset.
This is differential input headphone amplifier, which comes from Maxim MAX97220A,
used to drive external headphones.
Here is the headphone jack and audio interface.
Well. That would be all for today’s teardown.
The bottom and the inner middle plates are made of metal to enhance heat dissipation.
There are also small fan and air vents on the front and back sides for heat dissipation.
Every single port has overcurrent protection chip, used to prevent damaged components from
affecting the dock.
And a variety of chips come from well-known manufacturers in the industry.
