A2-Class Micro-SD Cards
Raspberry Pi A2-Class Micro-SD Cards support higher bus speeds (DDR50 and SDR104) and feature a Command Queueing (CQ) extension that permits a degree of pipelining of random read operations. The higher bus speeds and command queueing extension help to close the gap between SD card and NVMe SSD performance. The Raspberry Pi A2-Class Micro-SD Cards are available in 32GB and 64GB capacities.
