2 out of 5 eggsWATCH OUT !

Pros: Easy to mount drives. Adjustable fan speed. Speed was very good. Runs very cool with WD green HDD's.

Cons: Very minor noise from fan that exhausts through the top. Good for cooling efficiency but bad for people who sit things on it.

Other Thoughts: The unit does NOT let the computer address the drives as true individual drives. It would not let Windows Home Server 2011 address the drives as individual drives (I wanted to create a soft RAID 5). The item was returned ($15 shipping on me) and I ordered a NexStar HX4 which sets up a hard RAID that has worked for me.

5 out of 5 eggsone year +

Pros: Flawless. I'm a torrent hound and I've stored 8 TB of data in this NAS. No problems. Running WD black and green.

Cons: None.

Other Thoughts: A 160 fan on top would have been better and quieter. It's not noisy unless you get like 5 ft. in a quite room and it's working hard.

4 out of 5 eggsUbuntu Linux with raid

Pros: - Cools great once you up the fan speed. 52-55 degrees C. on all drives
- USB3 and Esata both work
- Units continue to work under high IO stress
- Each unit has a 4-disk aidz pool and I get 140 MB/sec write speed.

Cons: - USB3 JMicron controller on unit does not work well with linux. It spins drives down as soon as there's no USB connection and unfortunately, the computer can't wake them up on its own since it doesn't see past the USB hub/bridge. I had to unplug and plug them back in to turn them on. ie, drives didn't persist through a reboot. Lots of research showed the problem was in the JMicro controller and would probably get a firmware update soon to fix it. I switched to esata instead and everything works beautifully. (really, USB3 shouldn't be used anyway if you want rock-solid production-quality stability)

Other Thoughts: - I wish the bottom of the cylinder was open so I could stack the units. I own multiples and they take up a lot of surface area because you can't stack them.

2 out of 5 eggsMust Perform Firmware Upgrade to Stop Disconnecting Issue

Pros: Once firmware upgrade was performed it seems to be working well so far.

Cons: Look for the review by Anonymous on 5/7/2013 9:08:22 AM - doing this was the ONLY way this thing would stop disconnecting while I was copying several TB's of data.

2 out of 5 eggsBe wary using with Mac OS X

Pros: It's an inexpensive way to get lots of external storage. The case while plastic isn't too bad.

Cons: Is spotty working with Mac OS X.

Other Thoughts: I worked directly with Vantec trying to sort out why drives in this unit kept disappearing from the desktop. After upgrading firmware (only possible with Windows) at their suggestion the problem got worse not better. I decided it was time to call it and purchased a unit designed to work with Mac OS X. It cost more, but at the end of the day, it worked and worked well. This unit probably works just as well with Windows, but certainly think twice if you are going to try this with Mac OS X.

4 out of 5 eggsGreat unit. A little wonky to setup, some questionable design decisions

Pros: 4 Drive bays with only 1 plug and cable. Attractive. Functional.

Cons: Questionable design decisions, harder to setup than it should be. Documentation is typical unhelpful garbage

Other Thoughts: This was just what I was looking for. A multi bay NAS box for my plethora of hard drives and for secure storage. On the plus side, it works and its attractive. On the negative side, why is the power switch on the back? Why is the drive access on the back? The LED's are a bit bright and it is a real PITA to setup if you dont know what youre doing. My story is I have 3 external WD hard drives that I wanted to put in here. I figured it would be a simple matter of removing the hard drives from the external enclosures they are in and put the drives in the 4 bay NAS box and turn it on. Not so easy. the 3 drives that came out of the external drive units did not show up in Windows Explorer but the 4th junk 80GB drive I had as a spare lit up first try. Long story short, I thought it was the fact that the WD drives were "Green" drives but it turns out that I simply had to partition them and format them. I thought that since they were in use in the external hard drivecases they came in, that I wouldnt have to do that but I guess because if their size (2TB each) it was necessary. Unfortunately, figuring this all out only happened because of my computer experience. If I was a newbie, I never would have thought to look where I did.

3 out of 5 eggsWeak power supply

Pros: Inexpensive unit. Works well. Shuts down drives when USB power is turned off. It's USB 3 and very quick. Seen data rates of over 40 MB/s with mechanical spinning platters.

Cons: The unit comes with an under powered power supply. The original power brick is 5.42 amps. While using the default power supply, I experienced the unit resetting or cutting out, like many users have complained about.

I purchased a more powerful power brick and have no problems since. The replacement power brick is 7 amps.

I cannot give this 5 stars as I consider an under powered power supply to be a design flaw and a larger supply should have been provided.

Other Thoughts: I'm using this with my old desktop drives. I am parting off my desktop and going with a sweet gaming laptop. When I first got the unit, it did the cutting out/stutter thing that everyone complains about. I replaced the power supply and the unit works perfectly with 4 drives under heavy load.

People complain that the fan doesn't keep the drives cool under heavy load. I have not experienced this. My only thoughts are that these people are doing serious video, audio or graphical rendering with their drives. I wouldn't recommend this unit for high performance spinning disks that will be under heavy load, like the 10k/15k Raptor drives.

1 out of 5 eggsDOA

Pros: Easy to assemble without instructions; helpful tech support on the phone.

Cons: Dead on Arrival. Tech support was unable to offer help other than to advise retuning it. Printed instructions give no clue as to the use of the rubber pads or where to install them. Does not include the port replicator needed to use the eSATA connector.
