Internal memory is the memory where all the data of the mobile device is stored, the operating system, applications, photos, videos, music, chats, are stored in this memory so it is important to know if the device we are going to buy has of enough storage space for our needs.
The internal memory in mobile devices is equivalent to the hard drive in computers.
Very few devices have the option of incorporating 1 TB of internal storage, it must be borne in mind that 1 TB is 1000 GB, so it can be said that it is practically impossible for one of these devices to run out of storage space.
It is evident that a device with 1 TB of storage will not be obsolete for a long time, however for most users it is an excessive amount and not recommended.
Keep in mind that it is not advisable to save so many files (photos, videos or documents) on a mobile device that we can lose, they can be stolen or it can break at any time, losing all that information in an instant. It is recommended to back up photos, videos, emails or chats to a cloud storage service or an external hard drive to preserve this important data.
