The sd card library and fatfs example was introduced in SDK 12.2.0. FATfs is a third party library, see here. SPI is used at the bottom to communicate with the SD card, so it should not in theory be a big problem to port it from SDK 12.2 to SDK 10. There are also other people on the forum that have made libraries. Here is one that works with SDK 11. Here is a blogpost about interfacing the SD card directly without a file system (like fatfs). I do not know of any library that uses SDK 10.
