5 out of 5 eggsReputable customer support

Pros: This product has all the feature that I was looking for my home media storage; RAID, USB 3.0 and the option of sleep mode. It takes two of my 4TB drives without any problem. I like the idea of the fan control so that I can adjust it anytime if the drives get too hot. Pretty simple to install the drives and computer detects the drives right away. No hassle on the installation at all. Simple plug and play.

Cons: None.

Other Thoughts: At first, I was getting USB 2.0 speed and I was frustrated that my product was defected. So I promptly called the customer service from icydock and they were very helpful and patiently troubleshoot with me step by step. Finally, we figured out that it was my motherboard's USB 3.0 driver issue. I had to update my USB 3.0 driver and now I can finally see the USB 3 speed that I was expecting. Great experience with the customer support!

5 out of 5 eggsReliable product

Pros: This enclosure has a sturdy structure and speedy USB 3.0 transfer rate. The cooling fan keeps my drives cool at all time and it has adjustable fan settings too. I can barely hear the fan's noise when it is on my desk and the best thing is that the LED in the front can be turned off so it would not be distracting. I also like the simple tool-less installation, all you need to do is pop the drives in and the computer detects them right away. This is the best USB 3.0 enclosure I've ever had!

Cons: None so far, I will update if I find any problem.

Other Thoughts: Would recommend!

1 out of 5 eggsOnly shows 4G available

Pros: None. It does not work.

Cons: When I plug the drive in, it shows only 4G available. I have had the drive a month, but only got a chance to install it today. No RMA option on the Newegg website since I am 5 days past the 30. and no other way to return given. I will never buy from NewEgg again!

1 out of 5 eggsJunk

Pros: Looks nice

Cons: Cheap, fan dial is barely operable, reset button was off-center and difficult to access. Fan wasn't working properly (due to the dial) causing brand new drives to fail. Returned all for refund.

3 out of 5 eggsStopped working after a month

Pros: Slim, fast, quiet

Cons: none

Other Thoughts: Bought it a month ago. Stopped working after a month of use. I do have to say that their customer service is excellent. Will get a refund through NewEgg and get another one because it is faster.

4 out of 5 eggsgood speed

Pros: -slim, save space
-good look
-metal exterior, silver?
-fan, decent power
-did I mention speed?
-easy to setup

Cons: -came with 1 semi loose/broken clipper
-fan a bit loud? could be two HDD running thats why

Other Thoughts: start with the CON, broken or loose clipper, latch releases itself very easily with slight pressure or shock, something i can live with.. I guess.

fits two HDD and very slim, metal exterior to release heat, silver/white colored won't absorb light, keep it even cooler than regular black enclosure, just tiny bit cooler..

could definitely feel the fan running, and heat coming out of it, fan is doing its job for something so tiny.

two HDD measured in sequential 2MB write at QD1 (normal file copy transfer for large, movie/rar/iso/music files) at 320 MB/s with two barracuda 3TB drives, QD4 in CDM shows at 340 MB/s, it'll go even faster with velociraptor or SSDs inside but storage otherwise is wasted.

5 out of 5 eggsNice enclosure

Pros: Fast, keeps drives cool, just works like it's supposed to.

Cons: Having to wait for it to be released....

Other Thoughts: Got this enclosure as I wanted a RAID 1 system after a previous external HD died on me causing me to spend a ton of $$$$ to get the data recovered. A lot of the other RAID enclosures seem to have so-so reviews so I decided to wait for this one to be released and I'm glad I did.

With two 7,200 RPM drives (3TB Hitachi's) the enclosure is fast through it's USB 3.0 connection. If you're worried that the enclosure is going to be slow.... don't (Unless you are going to use a 2.0 connection LOL). I'm sure it would be ever faster in RAID 0 but after my last failure my nerves just wouldn't let me do it!

Installation was easy, just plug it on and turn it on, drive should be recognized as whatever RAID mode you set it to. Formatting took several hours but that's par for the course with 3TB drives.

The outside gets slightly warm, but that's because the solid aluminum acts as a heatsink along with the fan. I don't think you'll have to worry about drive failure caused by heat in this thing.

So would I buy this again? Absolutely. It does what it says it does and does it well. For the price, you can't go wrong.
