Apacer based the Instant Keychange™ function on AES encryption, and it can be trigged either via hardware or software. Destroying the original key and creating a new one takes less than a second – much faster than traditional forms of drive erasure.
When the crypto command is accessed, the cipher key is destroyed and all data on the disk is unable to be read. Because there is no need to overwrite the data, Instant Keychange™ only takes a few milliseconds to make the disk unreadable compared to other sanitization methods which can take several minutes depending on the number of passes and the size of the disk., but it is functionally unreadable and therefore completely protected.
