Tablet memory cards are typically used to expand the available storage capacity in a tablet or mobile device. Memory cards also allow you to transfer data such as photos, music and video to and from other devices quickly and easily. Apps and games are constantly evolving and becoming more complex, cameras are supporting higher resolutions and file sizes are increasing. If you’re running out of storage space on your tablet or mobile device, there’s most likely a memory card to suit both your needs and available budget.
The most common type of tablet memory is SD (secure digital). There are three main types of SD cards available based on their physical size; standard SD, miniSD and microSD cards. Before buying an SD card check your device’s specs to see which type of card it requires as they are not compatible with each other. If your tablet has a USB slot, you can also invest in a USB flash drive (also called USB stick or thumb drive) which you can plug in for additional storage.
The key specs of tablet memory include capacity, speed and SD card type. Capacity is measured in gigabytes and determines how much data can be stored on the tablet. As a rough guide, a 32GB or 64GB card can store hundreds, or even thousands of photos and video clips. Speed is important because it determines how quickly the tablet can access the data. It’s measured in classes which indicate how many megabytes per second (MB/s) can be transferred between the card and device. If you want fast storage for your tablet, look for a card with a higher Class number. There are 4 SD card types available including SD, SDHC, SDXC and SDUC. They mainly differ in the range of available capacities and their data read/write speed capabilities. SDXC and SDUC are the newest types of card and have the highest speeds and capacities.
