It looks cool and I'm intrigued by it but man, its kind of expensive considering its cost with NO storage. For a lot less, I got a 5 bay Raid unit. It is cool how you can keep adding various sized disks but I'm not sold yet at that price point. Plus USB 2.0? I've seen it demo'ed in person at least twice, it seems like a smart idea. Its proprietary and I don't believe you can gang them up. But I think it initially seems a few hundred bucks too expensive for what its providing. Plus it or a Raid 1, I'm never going to sleep at night with just one, even two sets of data.
