Product Introduction
PCIe TO M.2 (A) is a PCI-E to M.2 adapter card used for upgrading hard drives SSD solid-state drive cards, and supports CM4
Characteristic
- Supports NVMe protocol M.2 interface hard disk protocol, high-speed read and write, high work efficiency
- Only supports CM4 expansion board
- Support Raspberry Pi Compute Module 4
- Compatible with M.2 hard drives of different sizes
- On board work indicator light, the LED stays on when powered on and flashes during reading and writing, indicating the clear working status at a glance
Instructions for use
Tutorial on mounting a hard drive to CM4
Format Hard Disk
- Insert the hard drive into the corresponding position of the PCI-E to M.2 adapter card and secure it with the screws in the screw pack.
- After powering on and starting, perform lspci to check the PCIE device
- Execute sudo mkfs. ext4/dev/nvme0n1p1 to format the device (mkfs. Then press tab to see many different suffix names, which are the format you want to format)
Wait for a moment, when done appears, it means that the formatting has been completed.
Mount
Create mounting directory
sudo mkdir toshiba
Mount device
sudo mount /dev/nvme0n1p1 ./toshiba
Check disk status
df -h
Mount hard drive
- Create a new directory as the disk mount point
sudo mkdir /home/pi/toshiba
- Execute the following command to mount the hard drive
sudo mount /dev/nvme0n1p1 /home/pi/toshiba
Execute again
df -h
You can see the hard drive we inserted and related information, indicating that the hard drive has been successfully mounted
- For different hard drives, their names may vary. Here, nvme0n1p1 is displayed. Please refer to the hard drive you inserted.
literacy test
Enter the directory of the mounted disk
cd /home/pi/toshiba
sudo sh -c "sync && echo 3 > /proc/sys/vm/drop_caches"
- Copy Raspberry Pi Memory Content to Hard Drive (Read)
sudo dd if=/dev/zero of=./test_write count=2000 bs=1024k
- Copy hard drive content to Raspberry Pi memory (write)
sudo dd if=./test_write of=/dev/null count=2000 bs=1024k
- Note: Raspberry pie is more affected by different cards and different environmental testing effects
