Excerpt: 3rd Ultra I have purchased. Good gb/$ ratio. Nice compact size,very portable for travel. Carry as a safety backup of both my laptop & desktop during travel. No fear of data loss or "on the other computer" dilemma.<br />fast secure safety.
Summary: In short, I haven't been able to get this unit to work. I attempted to use it with my work computer, but I believe my company's encryption program is not a good match for the Passport. I also attempted to get it to work with my wife's Apple work computer, but was again unsuccessful. One first attempt with our home computer (no encryption), it was superb. Just like I expected. But on the second attempt, it hung, just as with the other computers.
Summary: I've only had it a few days so I don't know about longevity but I love the simple scheduled backups, the encryption and password security. I even used it to encrypt and secure my flash drives as well (I leave them lying around everywhere). it is a sleek design, very small and light, silent and conserves power by sleeping when not in use. Very happy.
