- Thread-topic: [Fed-Talk] Secure erase of SSD drives?
The thing that everyone seems to be missing is that because SSDs are not
magnetic media they do not suffer from the residual data issues that
Magnetic HDDs do. So in my limited knowledge and experience of the subject,
a single pass wipe on an SSD is as effective as a 35 pass wipe of a HDD.
Please if anyone knows more please correct me, but my understanding was that
SSDs are incapable of data scavenging once they are erased and overwritten.
