Therefore, it is not as easy to recover as HDD. On the HDD, deleting a file / data is like hiding a folder on our PC, just like hiding a folder. Hide is visible and not very easy to find. But you can find it.
Because you can still recover what you have destroyed, some people buy old HDDs, retrieve the data inside, and spread the word about privacy. The SSD will not have this at all, and once it is deleted, it will be replaced by another data / file that will be stored there. As a result, the old can never be found.
