Expected Result

Take Raspberry Pi 4B as example

• Insert the module to 40PIN GPIOof Raspberry Pi 4B. Connect the USB interface of USB HUB to Raspberry Pu by the USB 3.0 Adapter.
• Connect 5V power supply to the POWER ONLY port.
• Connect USB devices to USB ports *USB1~UBS4), the corresponding LED will turn on for indicating.

Working with Raspberry Pi

1. Hardware preparation

• Raspberry Pi 4B x1
• USB 3.2 Gen1 HUB HAT x1
• USB 3.0 Adapter x1 (You also use USB3,0 cable)
• USB 3.0 SSD x1

=2.Configure Rasberry Pi

• Enter the root directory of Pi

cd ../..

• Enter the directory of USB3.0 SSD

cd media/pi/xxx (xxx is the name of the disk)

• Free memory

sudo sh -c "sync && echo 3 > /proc/sys/vm/drop_caches"

• Copy 2G data to the SSD disk.

dd if=/dev/zero of=./test_write count=2000 bs=1024k

• Copy 2G data to the Raspberry Pi

dd if=./test_write of=/dev/null count=2000 bs=1024k 

3.Working with Ubuntu (Raspberry Pi)

• Search disk in menu->Enter->Open the disk

• Choose the correct disk and click the Benchmark Partition option in the Menu

• Click Start Benchmark，Check Perform write-benchmark. and keep other default settings.

• Input the user password and authorize.

• Test

Working in Windows PC

1.Connect the USB port ot USB3.0 of PC, and you can copy file to SSD

• Copy file to the PC

• Copy file to the portable SSD

2.Connec the USB to USB3.0 Port and connect four phones at the same time
