One man's review: I have two of the ProBox 4-bay devices. While they were great for a while, both ended up somehow with greatly diminished performance and connectivity issues. Confirmed between two different PC's, multiple USB ports (including a PCIe USB card). Connecting HDD's directly to SATA didn't result in any performance degradation or connectivity problems.
I scrolled down the page and see the 4 bay Yottamaster for $90 after $10 coupon. Don't have it myself, but see a lot of posters recommend it.
