Storage system, file storage and reading method, and terminal device

An electronic device comprising:

• a universal flash storage (UFS);
• and
• a processor in communication with the UFS, and configured to:
• configure a data storage form of a first logical unit in the UFS as a first storage form and a data storage form of a second logical unit in the UFS as a second storage form, wherein the first logical unit and the second logical unit are mounted on a same directory of a file system, the first storage form is different from the second storage form, and read/write performance of the second storage form is higher than read/write performance of the first storage form;
• determine first information in response to a request for creating a new file in the UFS;
• select the first logical unit or the second logical unit based on the first information create the new file in a selected logical unit;
• obtain information about a quantity of applications installed by a user on the electronic device;
• determine whether the quantity of applications installed by the user is less than a second threshold;
• migrate, based on the quantity of applications installed by the user being determined to be less than the second threshold, a first file in the first logical unit to the second logical unit;
• and
• arrange, based on the quantity of applications installed by the user being determined to be greater than or equal to the second threshold, the applications installed by the user in a descending order of use frequencies of the user, determine hot files of first K applications from the arranged applications based on a capacity of the second logical unit, the hot files of the first K applications having use frequencies satisfying a condition, and migrate the hot files of the first K applications to the second logical unit, wherein K is a positive integer.

A non-transitory computer readable storage medium, comprising computer instructions, wherein when the computer instructions are run on an electronic apparatus, the electronic apparatus is caused to perform operations comprising:

• configuring a data storage form of a first logical unit in a universal flash storage (UFS) as a first storage form and a data storage form of a second logical unit in the UFS as a second storage form, wherein the first logical unit and the second logical unit are mounted on a same directory of a file system, the first storage form is different from the second storage form, and read/write performance of the second storage form is higher than read/write performance of the first storage form;
• determining first information in response to a request for creating a new file in the UFS;
• selecting the first logical unit or the second logical unit based on the first information;
• creating the new file in a selected logical unit;
• obtaining information about a quantity of applications installed by a user on an electronic device;
• determining whether the quantity of applications installed by the user is less than a second threshold;
• migrating, based on the quantity of applications installed by the user being determined to be less than the second threshold, a first file in the first logical unit to the second logical unit;
• and
• arranging, based on the quantity of applications installed by the user being determined to be greater than or equal to the second threshold, the applications installed by the user in a descending order of use frequencies of the user, determining hot files of first K applications from the arranged applications based on a capacity of the second logical unit, the hot files of the first K applications having use frequencies satisfying a condition, and migrating the hot files of the first K applications to the second logical unit, wherein K is a positive integer.
