![]() ![]() The same rules apply for microSD cards as they do for SD cards. Hardware devices are also backward compatible with microSD cards, just like full-sized SD cards. MicroSD cards are more commonly used to expand the storage system of smartphones, drones, gaming devices and cameras. They’re also more versatile since they’re often available with an SD adaptor that allows you to use microSD cards in hardware devices that only support SD cards. MicroSD cards are the smaller-sized version of SD cards and the biggest difference between the two is the form factor. The four SD standards for microSD cards are: MicroSD cards share the same four SD standards as SD cards. To put it more simply, hardware devices that support newer standards are backward compatible with older standard cards, but newer standard cards can’t be used in hardware devices that only support older standards. SD-compatible devices are compatible only with SD standard cards. An SDHC-compatible device can use SDHC and SD standard cards but will not be able to use SDXC standard cards. Hardware devices that host the memory cards are backward compatible, meaning you can use older standard memory cards in devices that support newer standards like SDXC.įor example, an SDXC-compatible device can use SDXC, SDHC and SD standard cards. SDUC was announced in June 2018 and it will be a while before the SDUC cards are available and widely adopted in the industry. The SD standards represent a timeline of the evolution of SD cards, with newer cards allowing higher capacities and speeds. A mid-sized card should be able to capture hundreds, or even thousands of photos and video clips. In comparison, files are limited to 4GB in size with the FAT32 file system used by other card types.įor the average user, a 32GB or 64GB card is more than enough. ![]() Additionally, SDXC cards use the exFAT file system to support the large files that can be produced when recording video at high bitrates with cameras like Sony’s a7S III. If you shoot 4K video, you’ll most likely need an SDXC card since it has a maximum capacity of 2TB, which is plenty for optimal video recording performance. The main difference between the SD standards is storage capacity. The two standards that are more popular today for both SD and microSD cards are SDHC and SDXC. Both SD and microSD cards share the same standards: SD, SDHC, SDXC and SDUC, and microSD, microSDHC, microSDXC and microSDUC. This will usually indicate what SD standard the device requires. The first thing to consider when choosing a memory card is figuring out what type of card your device requires, which can usually be found in the instruction manual or on the manufacturer’s website. Which SD standard and capacity do you need? ![]()
