With every update and release gradually using more and more of your card, 8GB will soon become too small for a typical setup. You can claw back some space on your SD card, but with micro SD card prices being so low, now is the time to expand your storage. But for the full Raspberry Pi experience you will need the full install and that leaves you very little, if any, extra space on an 8GB card. Raspberry Pi OS can run on a card that’s as small as 8GB (see how to set up a Raspberry Pi) if used with the Lite version of the OS. We chose the 32GB capacity because it offers more than enough room for most use cases while not being appreciably more expensive than 16 or 8GB cards. At the time of writing, high performance 32GB micro SD cards can be picked up for $10! But which microSD card should you buy for your Raspberry Pi? To help find the answer, we tested ten different 32GB cards on a Raspberry Pi 4, a Raspberry Pi 3 B+ and a Raspberry Pi Zero W to see which offers the best performance for the money. MicroSD cards are a cost effective storage means.
