Which one of these RAID enclosures?

[TahoeDust]

I am going to be moving from my current 2 drive Raid 0 enclosure to a 4 drive enclosure that I can run Raid 5 in. This enclosure is used with my HTPC. I will be using 3TB drives. I have some Amazon gift cards so that is where I will be buying the enclosure. These two caught my eye because of price. One has the Raid hardware built in, the other comes with a raid card. Can you tell me which one of these would be recommended? Do you know of a better alternative through Amazon?

The Iview (round one) has the RAID card built in plus the USB 3.0 which is a nice extra (eSATA is sometimes problematic). The other looks to me like it's just got a SATA splitter to the drives which will be controlled by the included card. It might become a bottleneck on the system because each drive isn't directly connected to the controller.

Between the two, go with the first one.
