What are the different smartphone storage types

Internal memory

The Internal memory is a component of smartphones and tablets. It is used to store, manage and secure system and user data. In contrast to computers, mobile devices do not use hard drives, but a digital, non-volatile flash memorywhich is also used in USB sticks or for SD memory cards. There are smartphones with fixed internal memory as well as models with expandable memory.

The technology of the internal memory

The internal memory is digital flash memory with low energy requirements, on which a non-volatile backup of data is possible. Non-volatile means that the data is retained when there is no power, i.e. the mobile phone is switched off. The modules contain a memory block and a microcontroller. They are mobile, that is, they own no moving parts and can therefore not be damaged by vibrations. Although flash memory is slower than other types of memory, it has proven its worth for mass storage and mobile devices such as MP3 players, cell phones, and smartphones. This is mainly due to its economy and compact design. The lifespan of flash memory is limited and specified in erase cycles. Depending on the storage architecture up to two million write and erase cycles possible before it is necessary to replace the memory module and thus buy a new smartphone.

Typical memory sizes of smartphones and tablets

The first flash memories from 1990 onwards have reached a capacity of 4 megabytes. When it comes to smartphones Sizes between 4 and 128 gigabytes realistic. The entire internal memory is never available for backing up user data. Instead, the operating system and pre-installed apps and content already occupy part of the memory. Many popular smartphones from HTC or other manufacturers have an internal memory of at least 16 and an average of 32 gigabytes. Downward deviations primarily concern entry-level models, while a larger internal storage high-end smartphones remains reserved. The storage sizes are increasing continuously as files such as photos, videos and music take up more storage space due to higher resolutions and qualities.

How the internal memory in the cell phone can be expanded

The internal memory is a permanently installed component with limited capacity. While iPhones have a non-expandable flash memory, many smartphones with Android, for example the models from Wiko, offer the option of a memory card in compact microSD format can also be used. On many devices, the slot is on the side under a cover. Before buying a memory card, it is useful to take a look at the technical specifications of the smartphone in order to determine the maximum supported capacityt to be determined. Depending on the model, this is between 32 and 128 gigabytes, which are also available to the user. In the case of non-expandable storage, the data backup remains on the computer or online via a Cloud service as alternative.
