How much SD card is needed for Raspberry Pi 3 b+?

Question

Raspberry Pi

I want to make a web server based on raspberry pi for simple sites. What size SD card should you choose?

Answer 1

16GB is more than enough

Answer 2

The system itself without X will take 500-700 meters. Plus additional software such as http-server, database, some kind of php, plus data, scripts. If you don’t get too impudent and don’t make a file storage out of it, then 8 will be more than enough. Even with the swap partition and bootloader.
The main thing here is not to save on the card itself, because with active recording they are dying like flies.
If you know how to do it, you can generally load and mount rootfs over NFS without a flash drive over the network, for example.
