Secure Erase and Sanitize both securely erase the data on the SSD and reset the SSD to factory settings. To wipe SSD, sanitize or secure erase SSD will be much safer. If you use the same way of wiping HDD to wipe SSD, it may damage the SSD and decrease its lifespan. It is doomed that they need different wiping methods. HDD is essentially a metal platter with a magnetic coating that stores your data while SSD stored data on interconnected flash memory chips. Wiping SSD is different from wiping HDD since the way of storing data to SSD is different from the way to HDD. For example, if you would like to reuse or resell an old hard drive, you’d better wipe hard drive beforehand so that the old data cannot be recovered easily by any tools.
Wiping the hard drive is necessary in some situations.
