It seems that your SSD is showing signs of aging, since it has the following SMART counters:
End-to-End Error Detection Count. Raw 441, Normalized 1.
Reports the number of errors encountered during Logical Block Address (LBA) tag checks within the SSD data path. The normalized value begins at 100 and decrements by 1 for each LBA tag mismatch detected. The threshold value is 90.
Re-allocated Sector Count: Raw 3.
The raw value shows the number of retired blocks since leaving the factory (grown defect count).
It would be recommended to back up any important data that you may have on it. It may continue to work, however, the error counters mostly likely will continue to increase.
