I read many, many reviews before buying this diskless system, but I would have to say it has worked as expected thus far. I work in IT, so the setup was simple, but can see how it might be a bit of a challenge for the novice. From previous reviews, I decided to test the redundancy (by pulling out one of the hard drives) before adding my personal data to it. It worked flawlessly. Hope this helps you in your decision making process.
