When I first started using Sophos Safeguard Encryption, I had a normal hard drive. The boot up time of the computer was incredibly slow, and functions within the operating system were also much slower than compared with a non-encrypted drive/pc. I upgraded to a solid-state drive, and away went all the speed problems. Other than the speed, the only other thing I dislike is the logon interface which pops-up before the PC starts to boot, I feel this could be a lot nicer, and not as plain as it is presented (but this is obviously limited by graphic performance in the boot sequence).
