When disposing of SSDs, what method is most secure?

A.  Degaussing

B.  Overwriting

C.  Physical Destruction

D.  Reformatting

Answer:  C

Explanation:

Physical Destruction: SSDs (Solid-State Drives) store data differently from traditional hard disk drives (HDDs), making them more resilient to some traditional data destruction techniques like degaussing. Physical destruction is the most secure method to ensure that data cannot be recovered.

Here's a breakdown of the other options:

Degaussing: Degaussing is effective for HDDs but not for SSDs. SSDs don't store data magnetically, so degaussing won't erase data from an SSD.

Overwriting: Overwriting could be an effective method for HDDs, but it is generally not recommended for SSDs due to wear leveling, which ensures that write and erase cycles are distributed evenly across all blocks. As a result, overwriting may not reliably erase all data.

Reformatting: This is the least secure option for any drive, as it often leaves data intact and recoverable.

Therefore, the most secure method for disposing of SSDs is physical destruction.
