I agree that in most cases the access-time argument is a red herring. Back when I wrote SFS (DOS-based FDE that ran on 386's), I got plenty of feedback from users that the slowdown was barely or not at all noticeable. The only time I've really noticed it (using current FDE software, not on a 25 MHz 386) is when copying large amounts of data onto an encrypted partition, but that's (a) a very rare event and (b) somewhat slow anyway even for an unencrypted copy.
