Buying Guide
Capacity and Speed Class
Your Raspberry Pi 4 can boot and run from cards as small as 4GB, but 32GB or 64GB is far more comfortable for installing applications and storing files. Speed class matters just as much: Class 10 or U3 cards deliver the read and write rates needed for smooth desktop use and 4K video playback. Cards like the SanDisk Extreme PRO with UHS-I U3 ratings provide excellent throughput for heavy workloads.

Preloaded vs. Blank Cards
Preloaded cards come with Raspberry Pi OS already installed, so you can insert and boot immediately. This is ideal for beginners or anyone who wants to avoid the flashing process. Blank cards require you to download and write the OS yourself, but they often cost less and let you choose any operating system.

Compatibility and Reliability
Most microSD cards work with the Raspberry Pi 4, but some cards have better controller firmware and error correction. Look for brands like SanDisk, Beamo, and STEADYGAMER that have proven track records. The Pi 4 supports SDHC and SDXC formats, so any card from 4GB to 128GB should work.
