Pros: Sleek design and stays cool. Love the Gbit ports and I use the stock firmware (not DD-WRT).

Cons: Just stops accepting traffic 2x per week. For what I use it for it's OK but man since this is a recurring pattern with this device the leadership and management in ASUS should be retrained on how to develop a product that should run 24x7 w/o a hiccup.

Pros: This is an update from my 4/26 review. My NAS cluster is humming along smoothe. I have a Hitachi Ultrastar 2TB, a WD RED 2TB and a WD RED 4TB in a Ubuntu & DRBD configuration. So raw capacity of the cluster is effectively 8TB in an active/passive configuration.

Never had a problem with the Ultrastars; Hitachi doesn't even KNOW my name (knock on wood).

WD does know who I am but nonetheless I am pleased with how I got here.

The WD RED drives perform well and to my satisfaction. There is a slight performance hit with the REDs compared to the Ultrastar but this was expected; my clients do not see it at all and the power drain is much less. The Ultrastars are much more expensive.

Cons: Other people have had worse situations than I have had so hopefully as the product quality and supply chain matures WD enters into the sweet spot with these drives.

Other Thoughts: 4 eggs still warranted as far as I am concerned to show some solidarity to the community of RED users out there.

My suggestion to everyone is that if you get a drive that is DOA, use WDC's RMA process immediately. This way you take at least one middle-man out of the supply chain in terms of getting your replacement.
