Transcend JetDrive Lite is custom SD Card for Macbook Air 13". Very slim after installed.

Create shorthand to SD Card

After mounted SD Card, You can access SD Card from /Volumes/sdcard. But I come from android. So /sdcard is better.

echo -e 'sdcard\tVolumes/sdcard' | sudo tee -a /etc/synthetic.conf

Reboot and now you can use /sdcard.

Prevent SD Card from sleep

😭😭😭 Update 2020/05/05 — disksleep did not worked 😭😭😭
SD Card always reject when lip the screen or sleep. To prevent SD Card from reject, use Lock Screen instead of sleep. If accidentally rejected, just re-mount SD Card manually.

I’m very happy with /sdcard. But sometimes SD Card random lost when I lip the screen or when computer sleep. This is effect of disksleep.
