It has a standard size of 11 mm by 15 mm. It is mostly used for mobile phones for storing photos, videos and simple applications. It is still a secure digital card that has the same standard size of 11mm by 15mm.
Like the other micro SD cards, it has a standard size of 11mm by 15mm. MicroSD was offered as a compact storage option for mobile devices.
MicroSD cards contain the very same fundamental technology as SD cards , even with the same electromagnetic circuit interconnections, despite their significantly smaller size. Mini, as well as micro SD cards, have indeed been produced to address the storage requirements of cell devices. Similar to Memory cards, but with a wider range of storage space, more ports, a lower transfer rate, and older technology.
A micro SD memory stick typically holds up to 2 GB of data. Its usual dimensions are 11 mm besides 15 mm. It is primarily used for storing images, movies, and basic applications on cell devices.
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.
However, the speeds are based on manufacturer tests, so they may represent a best-case scenario rather than real-world performance.
