SSD
True of False
Degaussing data on a SSD has no effect
True
This command improves garbage collection by marking data as ‘invalid’. It helps improve performance
TRIM

Destroying objects is more secure than overwriting them
True
A data owner’s acceptance of a system certification and residual risk
accreditation
