Desktop card readers are more obvious and usually contain multiple slots. Look for the "SD" card slot. Insert the adapter into the SD card slot on the card reader. There's no universal orientation, except that the metal contacts must be inserted first. The card might slide in label-side up or upside-down. If you don't have the manual, gently insert the card; if you encounter resistance, flip it over and try again. Doing so opens Windows Explorer to view the microSD card's contents.
Step 2: Use a USB cable to connect the phone to the computer. If you are using a microSD to SD adapter, make sure the Lock switch on the left side of the adapter card is slid up unlock position. You will NOT be able to modify or delete the contents on the memory card if it is locked. If the laptop does not have a card reader with an SD card port, insert the installation disk for an external card reader into the optical drive of the laptop.
When placed inside an SD card adapter, they allow you to transfer data between your device and a computer. SD cards permit the easy transfer of files between devices. Remove the micro SD card from your device. The included SD adapter allows users to conveniently swap the microSD card from mobile phone to camera or any other SD compatible host for easy file sharing and transfer.
In , the microSD card debuted at about one sixth the size and half the thickness of the SD card. An SD card measures 32 by 24 by 2. A microSD card is much smaller than a standard SD card. When this happens you are not able to access the data on your microSD card. There's a lot more to them than you might realize, however. It's surprisingly easy to fall into a number of traps: overpaying, experiencing terrible performance, or the card not working in your device at all.
Are all microSD cards the same? Far from the case. Read on to learn all that you'll need to know. The fourth format is SDUC. 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.
