Choosing best SD card for small home computer
When choosing a sd card for device like Raspberry PI, Odroid XU4 or other similar devices, it all depends on size of need. Always look for class 10 cards and with bigger sizes comes bigger speeds.
For a computer thats always on, its recommended to get a bigger sd card and keep some of the card empty for better life time cycle. We recommended for most devices SanDisk Ultra 64GB microSDXC or Samsung 64GB EVO Select Micro SDXC. For Raspberry PI 1 you will need a adapter for microSD card. Raspberry PI 2/3 comes with microSD card slot so no adapter is needed.
Raspberry PI also offers preloaded SD cards: Raspberry Pi 16GB Preloaded (NOOBS) SD Card and Raspberry Pi 8GB Preloaded (NOOBS) SD Card
