Virtual-Hideout posted a review on the Kingwin Big Drive RAID Enclosure

Let's be honest, this is a very cheap product, right on the very bottom end of any competing products. It looks good on the outside, but it's very basic inside. The manual does a great job of explaining the different RAID levels, but that's about it. The codes that it describes for the front LED's are nigh indecipherable. That said, being so cheap makes it really attractive to a lot of people, and without any performance or setup problems, I can't see any real reason *not* to get it. As long as you understand you aren't getting the easiest to use, or most feature rich enclosure
