mini-SD, SD, CF, and USB flash storageCompact Flash (CF)cards are larger than other memory card types - 42.8 x 36.4 mm, and either 3.3mm or 5.0 mm thick. Later generations includeCFast (CompactFast)andXQD. Compact Flash cardsare popular in high-end digital single-lens reflex cameras.Secure Digital (SD)cards come in three different sizes: the original (32.0 x 24.0 mm), mini-SD (21.5 x20.0 mm), and micro-SD (11.0 x 15.0 mm). Full-sized SD cards are the most popular format for digitalcameras, while micro-SD is the dominant format for tablets and smartphones. They all use the sameelectrical interface: to use a micro-SD card in a full-sized slot, you just need an adapter. The originalSD format supported cards up to 2GB.SD high-capacity(SDHC) supports up to 32 GB, andeXtended-capacity(SDXC) up to 2 TB.Note:A fourth type, Secure Digital Input Output (SDIO), fits into a SD card slot but doesn'tstore data. Instead, it's an input/output adapter, such as a network card.USB flash memory, also referred to as amemory stick,pen drive,thumb drive, orjump drive, is a solidstate memory card enclosed in a case with an integrated USB interface.
