Pros: Good design. Great price. Very sturdy.

Cons: Needs to be about 2" longer to truly hold an 8x13 mother board. I Had to mod the front drive bays to get my mobo to fit. This is why I didn't give it 5 eggs. Could use the second 80mm fan for even better airflow.

Overall Review: I bought two of the D-406-B6SA (with 6 hot swappable drive bays) for my office to build as replacement servers. I run VMWare so I can run several virtual servers. I used the Tyan S5396A2NRF Tempest i5400XT mobo in them. It would not have fit, but I moved the 3.5" bays to the bottom and cut them back to clear the board. I bought the D-406-ND for my home. I won't be putting in a full size mobo and I don't have the added drive bays because I use an external ESata tower to help keep things cool. I will be modding the front panels to add two 120mm fans for proper air flow that is quiet. I am primarily doing this because my 1u servers at home are driving me crazy with all the noise from the fans.

Pros: Can handle drives larger than 1tb.

Cons: Worked for about 2 months then just died.

Pros: Cheap. Good Performance.

Cons: Shipping. Not related to the drive, but Newegg needs to prep these better for shipping. I am assuming that is why a lot of people are getting DOA's.

Overall Review: I have 10 of these already in a 15 bay External sata Enclosure hooked up to a VM Server and they all work perfectly. I don't know how quiet they are because the room they are in is very loud(server room). I am ordering 5 more to fill up the enclosure. I only gave 4 stars because of the packaging that NewEgg does. Performance of the drives has been outstanding.
