While on an SSD, the enabled Trim by default tells the operating system which data block can be erased when it is no longer in use, and thus it zeros out the used block when a deletion operation occurs. Hence, the deleted data can be recovered before it is overwritten. This indicates that the old data has been overwritten. In actuality, the deleted file will typically still be present on the medium until a new file takes its place in the sectors that belonged to the deleted file. The sectors where the file had previously been stored will be designated as accessible if the deletion occurred on an HHD. Erasing on an APFS formatted SSD could be safer compared with an HDD. It depends on whether you are using an SSD drive with Trim or a standard hard drive. ![]()
