when the number of detection points with inconsistent read-write data information is lower than a first preset threshold value, judging that the memory is not damaged;
and when the number of detection points with inconsistent read-write data information is not lower than a first preset threshold value, judging that the memory is damaged.
In this embodiment, five detection points (i.e. five segments of physical addresses) are randomly extracted, whether the data of the writing operation and the reading operation are consistent and accurate is detected, and if there are 2 points or more than 2 points with errors, the memory is determined to be damaged.
S120, detecting the video recording and writing speed of the memory.
Further, performing video recording and writing speed detection on the memory includes:
