So, it is not possible to mount the adopted storage to another device because of its encrypted nature. The key used to encrypt the data on the SD card is stored on the Android device’s internal memory. With Adoptable Storage, Android encrypts the external SD card being used as internal storage, thus, it gets tied to a specific Android device. Your Android will literally adopt the storage It warns about the performance of the external storage and may even decline to adopt if the SD card is extremely slow. Using the SD card as permanent storage would require more frequent read/write operation, and it would degrade its performance over time.Īndroid does a performance benchmark of your SD card to make sure it’s fast enough to match the internal memory. Even though they can store tons of data, they’re slower than the internal storage and have a limited number of read-write cycles. This is the painful reality of these tiny memory chips. Here are some pros and cons: SD cards are slow But everything comes at a price and so does the adaptable storage feature. Using your SD card as internal storage might sound good to your ears. While adopting a storage, whether an SD card or USB drive, Android formats and changes it’s FAT32 or exFAT format to ext4 or f2fs. Methods to do the same task existed earlier. Google introduced Adoptable Storage with the release of Android 6.0 Marshmallow.
