The Apricorn 4TB Aegis Fortress L3 and 1TB Aegis Padlock USB 3.0 bundle combines two hardware-encrypted portable external hard drives to provide robust data protection and fast file transfers. The Aegis Fortress L3 offers higher 4TB capacity with rugged aluminum construction that meets FIPS 140-2 Level 3 requirements for data security. Its 256-bit AES-XTS encryption protects files in real-time and allows read-only access to prevent tampering. The 1TB Aegis Padlock provides fast USB 3.0 speeds up to 10X faster than USB 2.0. Its 256-bit AES encryption chip is sealed by a protective epoxy coating. With no software or admin rights required, both drives provide cross-platform plug-and-play operation. They safeguard data through encryption key deletion if the incorrect password is entered repeatedly. Together these drives provide portable, secure external storage for backups, transfers, and access to sensitive files on the go.
