SD协会在CES 2009上宣布了新一代存储卡标准“SD eXtended Capacity”，简称“SDXC ”，将提供最大2TB的海量存储空间，是现有SDHC最大容量的64倍之多。

形象地说，2TB空间可以保存大约100部高清电影，或者60小时高清录像，或者4000多张RAW原始照片，或者17000张高质量照片。

容量突飞猛进的同时，SDXC的传输速度也有望达到300MB/s，差不多相当于USB 3.0 625MB/s的一半。

SDXC存储卡仍然基于NAND闪存技术，文件系统则是微软exFAT，已经得到Windows Vista SP1的支持。

SD协会预计在本季度公布SDXC规范，同时SDHC、Embedded SD、SDIO等现有规范也会有所升级。
