The Corsair Padlock 2 uses full AES 256 bit encryption available through its satellite board. User data is encrypted on the fly as it is written to the NAND flash and decrypted on the fly as it is read from the NAND flash. Encryption and decryption occurs via the controller on the satellite board.
We recently encountered this drive for data recovery and the satellite board was failing and all the components were dipped in epoxy. Needless to say it was quite challenging to complete this recovery successfully but with hard work from our team, we were able to recover all the data for this law firm that was in dire need of its contents.
