Method, apparatus, storage medium, and terminal for optimizing memory card performance

An apparatus for optimizing memory card performance, comprising:

• a preset-time-interval determining module configured to determine a plurality of different preset time intervals, the preset time intervals being determined beginning from the clock-cycle starting points;
• a sending module configured to send test data to a memory card by using each of the preset time intervals respectively;
• a reading module configured to read from the memory card the test data corresponding to each of the preset time intervals;
• a comparing module configured to compare the test data sent using each of the preset time intervals with the corresponding test data that is read, and in response to the sent test data and the read test data being consistent, then determining that the preset time interval is valid;
• a target-group determining module configured to determine at least one group of preset time intervals, each of the groups of preset time intervals containing a plurality of valid and successive preset time intervals, and determine a group of preset time intervals containing a maximum number of preset time intervals as a target group;
• and
• an average-value calculating module configured to determine an average value of all the preset time intervals in the target group as a time interval for writing to the memory card.

A non-transitory computer readable medium storing a set of instructions that is executable by at least one processor of a computer system to cause the computer system to perform a method for optimizing memory card performance, the method comprising:

• determining a plurality of different preset time intervals, the preset time intervals being determined beginning from clock-cycle starting points;
• sending test data to a memory card using each of the preset time intervals, respectively;
• reading from the memory card the test data corresponding to each of the preset time intervals;
• comparing the test data sent using each of the preset time intervals with the corresponding test data that is read;
• in response to the sent test data and the read test data being consistent, determining that the preset time interval is valid;
• determining at least one group of preset time intervals, each of the groups of preset time intervals containing a plurality of valid and successive preset time intervals;
• determining a group of preset time intervals containing a maximum number of preset time intervals as a target group;
• determining an average value of all the preset time intervals in the target group as a time interval for writing to the memory card.
