The Application Performance Class 2 (A2) is defined by SD Physical 6.0 specification. The SD Memory Card Formatter was created specifically for memory cards using the SD/SDHC/SDXC standards. SD Host Devices can only use SD memory cards. SDHC Host Devices can use both SD memory cards and SDHC memory cards. SDXC Host Devices can use SD memory cards, SDHC memory cards and SDXC memory cards. SDUC Host Devices can use SD memory cards, SDHC memory cards, SDXC memory cards and SDUC memory cards. SD memory cards can be used with SD devices, SDHC devices, SDXC devices and SDUC Host Devices. Click here if you want to format your SD memory card without SD card formatter tool on MacOS. SDHC memory cards can be used with SDHC devices, SDXC devices and SDUC Host Devices. SDXC memory cards can be used with SDXC devices and SDUC Host Devices. SDUC memory cards must only be used with SDUC Host Devices. Interoperability of host devices and cards are shown below. Before inserting your SD memory card, confirm the device is compatible with the SD standard by locating an SD logo and other symbols on the device or referring to the device’s user manual or manufacturer information.
