Each format is defined in the SD specification, but they don't all work in the same way. As a result, these formats are not backward-compatible. You cannot use newer microSD cards in hardware that only supports older formats.
In addition to checking that a card's format is compatible with your hardware, you need to check a few other details, too. First, hardware supporting microSDXC slots doesn't automatically support all of the other types of microSD cards available. There's no guarantee that your GB card will work with other microSD card types, so investing in a microSD card adapter might be a good idea. If you're planning to use your microSD card with your Mac at any point—for example, to move files on and off—you also need to ensure your computer supports the file system that the card is formatted with.
Windows has supported it for over a decade but macOS only since version To benefit from the increased performance of UHS, your hardware needs to support it. Identifying the difference between microSD cards in terms of speed is even more complicated. There are no less than six ways to show how fast a card is, and it's not uncommon for manufacturers to use all of them. The Speed Class shows the minimum write speed of a memory card in megabytes per second.
There are four Speed Classes to choose from:. Showing the base-level performance differences in microSD cards helps the manufacturer communicate whether a card is suitable for your needs. Because this attribute tells you nothing about the SD card's maximum possible speed, it's technically possible for a Class 2 card to be faster than a Class 6 card.
Class 10 cards should always be noticeably faster, though, as they have a bus speed of 25MBps compared to Of course, the devil is in the details. We're listing it as a separate category because some manufacturers list both classes on their cards. The two UHS Speed classes are:. The Application Performance Class specifies a minimum sustained write speed of 10MBps, along with a minimum random read and write speeds measured in input and output operations per second IOPS.
This guarantees an acceptable level of performance when storing and running Android apps on your card. The Application Performance Class is something you can look at when you're planning on installing Android apps on different types of microSD cards. It isn't a necessity, though, as SD cards without the A-rating may still perform adequately.
The Video Speed Class sets a minimum sequential write speed, which is essential when shooting video. The higher the resolution of your video, the faster the speed you need. There are five classes for video:. While it's generally safe to assume that a higher Speed Class correlates to faster all-around performance, and UHS cards faster still, some manufacturers also quote a maximum speed for their products.
These speeds are in megabytes per second and help you pick out the absolute fastest microSD cards. But please pay attention, you should back up the important data saved in this card first, and then perform formatting. It is highly recommended that you use MiniTool Partition Wizard to perform formatting. Step 5: Click the Apply button to complete the changes once you go back to the main interface.

Download Partition Wizard. Note: The feature only tests the partition with drive letter. If you seek high performance and large capacity, SDXC is the better choice. This card can not only help you save more pictures but also better handle the transfer rate of high definition recording. The longevity of SD card depends on how you use it. Learn more. Ask Question.

Have you try to put the card as it was GB and check how it is recognized? RomeoNinov The camera reports 'sd card error' then offers to format. After it formats and reboots it reports 'sd card error'.
