SD card quality is a critical factor in determining the overall user experience for a Raspberry Pi single-board computer. Recent cards support higher bus speeds, and the command queuing extension, which permits a degree of pipelining of random read operations; together these close some of the gap between SD card and NVMe SSD performance.

This 32GB MicroSD card from Raspberry Pi is the preferred choice for those looking to run and boot an OS off of a MicroSD card with the Pi. It has been thoroughly tested, vetted, and selected by the Raspberry Pi foundation for use with the Raspberry Pi and Raspbian operating systems.
