Sanitize or Secure Erase SSD? What's the Difference?
Wiping SSD is different from wiping HDD
Wiping the hard drive is necessary in some situations. 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 SSD is different from wiping HDD since the way of storing data to SSD is different from the way to HDD. HDD is essentially a metal platter with a magnetic coating that stores your data; while SSD stored data on interconnected flash memory chips. It is doomed that they need different wiping methods. If you use the same way of wiping HDD to wipe SSD, it may damage the SSD and decrease its lifespan. To wipe SSD, sanitize or secure erase SSD will be much safer. But which one to choose?
Sanitize VS. Secure Erase SSD: What's the Difference?
Secure Erase and Sanitize both securely erase the data on the SSD and reset the SSD to factory settings. After you Sanitize or Secure Erase SSD, all data will be permanently removed on the solid-state drive and cannot be recovered. But there are some differences between those two methods.
Secure Erase only deletes the mapping table but will not erase all blocks that have been written to. However, Sanitize will delete the mapping table and will erase all blocks that have been written to. Thus, Secure Erase is faster to complete than Sanitize. But not all SSD support Sanitize. For example, if you want to know whether your SanDisk SSD supports Sanitize, you need to refer to the SanDisk SSD Dashboard to check it.
