Full Disk Encryption (FDE) is a method for encrypting the entire hard drive to protect your data. This includes the operating system and data
FDE works through the controller of the storage device encrypting/decrypting data as it is received back and forth.
There are many encryption algorithms used with FDE devices, the most common of which is 128-bit and 256-bit AES (Advanced Encryption Standard).
The Integral Crypto SSD uses hardware-based FDE and utilises 256-bit AES to protect your data which is FIPS 197 Validated - Certificate No. 1832.
