I'm thinking of installing Veracrypt and I read that it takes Veracrypt about 5 minutes to decrypt a 500 gig SSD. How is this possible? It takes me much longer to duplicate the same 500 gigs on my SSD!
Can someone explain how this is possible?
This is how I analyze the situation. The following are the fundamental tasks of each procedure:
1. Vercrypt has the computer read the data, decrypt the data, and then finally write the data on the SSD. It does this over and over again.
2. When the same computer copies 500 gigs on the same SSD, the computer reads the data and then writes the data on the SSD. It does this over and over again.
∴ Relative to the 2nd procedure of simply copying, the Veracrypt procedure is exactly the same except Veracrypt has the additional, complicated task of decrypting the data. Veracrypt has to take longer time, no?
How could the Veracrypt decryption be faster?
