Unboxing & Teardown
Front of the outer packaging
Back of the outer packaging
Opening the outer package, inside you’ll find: the hard drive enclosure, a C-to-C data cable, a lanyard, user manual, screwdriver, screws, an SSD extension board (for converting 2230 to 2242), and a magnetic ring (for Android phones without magnetic support—stick this ring to the back of your phone so the drive can magnetically attach).
Front of the drive enclosure: screen and glass cover, a button on the middle frame, and a ring of heat dissipation holes.
Side of the drive enclosure: two Type-C ports on the middle frame. HOST is the data port, PD 100W is the power input port.
Bottom of the drive enclosure: model number printed, anti-slip rubber feet (magnets are embedded in the feet).
Remove the two screws on the bottom to open the back cover, then you can install the M.2 SSD. There’s a thermal pad on the PCB, and a plastic film on top of it—remove this film before use.
Chips visible in the image below:
- V4852P M2408H: PMOS transistor, model JMV4852P, 30V/32A
- SC8724QFER: Southchip’s high-efficiency synchronous buck-boost converter, integrates four MOSFETs, supports 2.7–22V input and 3–22V output, fixed 5.1V output, up to 3.5A output current
- PS1045L: ASEMI ultra-low forward voltage Schottky diode, TO-277 package, 10A forward current, 45V reverse voltage
- SS54: SMD Schottky diode, max 40V reverse voltage, 5A forward current, low forward voltage (~0.55V), fast switching
- 6392 G37Y 7V02R: No available information
- 36Hek1: No available information, likely a DC-DC power chip
There’s also a large capacitor for power-loss protection, preventing file corruption during transfers and giving the SSD enough time to fully save the FTL mapping table.
The main controller and screen-related chips are on the back of the PCB, which requires removing the glass panel. Since it’s tightly glued, I won’t disassemble it here.
According to the manufacturer’s specs, the main controller is Realtek RTL9210, with front-end interface USB 3.1 Gen2 (10Gbps), backward compatible with Gen1 (5Gbps) and USB 2.0, and back-end interface PCIe 3.0 x2 (16Gbps bandwidth).

Review & Speed Test
I installed a 1TB Samsung PM991a SSD (2230规格), which required the extension board to convert it to 2242.
Plugged into a computer, idle power consumption (no read/write) is about 1.4W. The enclosure’s screen displays SSD temperature, model, capacity, health, power-on hours, real-time read/write speed, and USB connection protocol speed.
Under full read load, power consumption rises to about 5.5W.
Press and hold the button on the middle frame, release when “About” appears to enter the enclosure’s settings menu. Options include write protection, screen saver timeout, charging power (likely refers to the capacitor’s charging power for power-loss protection), and display language.
Press and hold the button, release when “SSD Info” appears to enter the SSD health page. Displays model, serial number, capacity, firmware version, number of unexpected shutdowns, remaining lifespan, power-on hours, power-on count, total reads, and total writes.
The enclosure has two C-ports: one connects to a phone, the other to a PD charger, allowing simultaneous charging and SSD read/write. However, Huawei phones only support up to 18W PD, so 100W PD cannot be tested.
Used the Weijian C5 Tester to read the E-Marker info of the included data cable. The cable supports USB3.2/4 Gen2, vendor code 0x0000, and PD3.1 20V 5A.
Connected to a PC and tested with AS SSD Benchmark: sequential read speed 979.59MB/s, sequential write speed 947.86MB/s, 4K random read 29.80MB/s, 4K random write 68.86MB/s.
You can magnetically attach the drive to an iPhone, then connect the cable to enable phone read/write. It supports external 4K ProRes video recording. For Android phones, attach the included magnetic ring to the back for magnetic mounting.
Thermal Imaging of Enclosure Temperature
Review and sample images of the Uni-T UTi261M thermal imager: https://blog.zeruns.com/archives/798.html
Thermal image of the enclosure at idle (no read/write), highest temperature is a PMOS transistor at 47°C (ambient ~20°C). The main controller is on the back of the PCB and not visible. Based on my review of another enclosure with the same controller, the controller runs around 55°C—quite acceptable.
Thermal image under full read/write load (without bottom cover), main controller temperature exceeds 90°C. It’s recommended to add an extra thermal pad between the SSD and enclosure (after adding, SSD temperature drops below 60°C).
Front surface thermal image under full load: screen area peaks at 36.6°C.
Side surface thermal image under full load: viewing through heat dissipation holes, internal peak temperature is 42.9°C.
Bottom surface thermal image under full load: peak temperature 37.5°C. (Due to metal reflectivity, the three black rubber feet appear hotter in thermal imaging.)
Heat generation is moderate—performance is quite good.
