Raspberry Pi is compatible with several operating systems. However, the Raspberry Pi OS is the officially supported operating system. Using a Raspberry Pi imager is a quick way to install an operating system on a microSD card. Pre-loaded SD cards are available for an easier and faster setup.
Several Raspberry Pi options, such as Raspberry Pi OS with desktop and Raspberry Pi OS Lite, are downloadable. Raspberry Pi's official A2 microSD cards offer enhanced speeds and command queueing. The quality of SD cards can considerably influence performance. These cards support DDR50 and SDR104 bus speeds and offer enhanced read and write performance on Raspberry Pi 4 and 5 models. Official SD cards come in 32GB, 64GB, and 128GB sizes, distributed blank or pre-programmed with Raspberry Pi OS.
