Is it Good to Use SD Card as Internal Memory?

The internal storage is used to install the operating system and save the pre-installed apps, the other apps and the data generated from apps. The external storage is usually designated to the portable SD card. But, is it good to use a SD card as internal memory? Here are some merits and demerits.

Merits:

When a phone closely runs out of the storage space, a SD card can expand the space. Then, you can install more apps and save much more data.

Demerits:

Of course, using a SD card as internal memory can save tons of data when the space of the phone has run out of use. Compared with the internal storage, a SD card reads and writes slower. The SD cards at low speed class can even affect the phone’s daily running.

In addition, a SD card has a limited number of read-write cycles. Using a SD card as internal memory will require more frequent read/write operation. Gradually, that will degrade its performance and lead to data loss.

Summing-up:

These are pros and cons of adopting a SD card as internal memory in an Android phone. It is suggested you use the internal storage by default. If you really need to change this setting, please read the above contents carefully.
