Why should Apple notebook be SDXC card slot instead of SD card slot?

Because the SD card is too backward and its capacity is too small, it can't meet the needs of the times, especially the SDXC card slot like Mac is more flexible to adapt to large-capacity cards. For photographers, the SD card is more than 16G. . In fact, this is not an SD card, but an SDXC or SDHC. Due to the limitation of SD card, the maximum is only 2G. . SDXC is the latest technology, and the theory can reach 2TB. . Therefore, Apple, which always likes to use new technology, will inevitably choose to use SDXC card slot. .
