About SD Card
SD card, short for Secure Digital card, is a non-volatile memory card format which is
the most widely-used in mobile electronic devices for data storage, such as
smartphones, digital cameras, MP3 players, etc. According to different storage
capacities and transfer speeds, SD cards come in many variants including standard
SD, miniSD, microSD, SDHC, SDXC and SDIO.
Why Partition SD Card for Android?
Most of Android users, including myself, have come across the situation that there is
not enough internal storage on their devices. For Android smartphones, internal
storage plays an important part, however, most of devices are designed with low
in-built storage capacity and cause limitation in apps installation. After storing
some photos and installing several apps, you may find the device begins to yell in
notification tray and alert “low space in internal memory”.
As a result, the overall
perform of the mobile phone will decrease. Users have no choice but to delete their
precious photos and favorite apps to free up the internal memory.
Luckily there is a solution to this problem. That is partitioning SD card to create a
second partition and move apps in order to save internal storage.
