How many external HDDs can you have in a Raspberry Pi 4 8gb?

Hello guys. I’m about to buy a Raspberry Pi 4 to be my farmer/harvester. I read a few people saying it can support up to 32 USB devices, but I wanted to confirm with people that already use it if this is true. How many external HDDs are you being able to store in your Raspberry Pis?
