I've read about the USB 3.0 issues others had with this enclosure, so to connect it to my 2012 Mac Mini, I ordered USB 3.0 to Esata Adapter Support Port Multiplier (Patent Pending) - U3esata which includes a port multiplier. So far, after a few days of use, everything is working as expected though I have not tested the USB 3.0 connection yet. With this set up, no special driver software was needed on the Mac.
I have two 3TB and two 2TB drives installed. Installing a drive is as simple as attaching the tray with two screws and sliding the drive into the enclosure. Unlike another reviewer, there were enough screws included. Each drive also has multiple partitions and the mac recognizes and mounts each partition separately. Moving the 2TB drives from other external USB enclosures went smoothly. The 3TB drives from seagate and western digital enclosures however needed to be repartitioned when placed in the Vantec. Once repartitioned, they worked fine. I've since added a 4TB drive and it is also working ok.
In terms of performance, copying a file from the mac's internal drive to the vantec reaches 85 to 90 MB/second. Copying a file from one drive in the Vantec to another drive within the enclosure runs at about 60 to 65 MB/second. In terms of power usage, when the enclosure is on but the computer it is connected to is off, the enclosure consumes 4 watts according to the killawatt meter. When the hard drives spin up during when the computer starts, power peaks at around 48 watts. Once it settles down, power usage levels off at 25 watts at idle and 30 watts when reading/writing to a drive. Again, this is with four hard drives installed.

I purchased this after returning other 8bay enclosures and another 5 bay. This Vantec units suits my needs. I do not use any RAID configurations. I simply use JBoD (Just Bunch of Drives). Now assuming you have port multiplier motherboard OR a PCIE card (which I have) that has port multiplier, then simply hook up and poooof! Extra massive storage. I have fan at max setting and pretty darn quiet. I have not done any stress tests to see actual performance as far as cooling/ venting drives from higher temperatures, but drives fairly cool to the touch by comparison to other enclosures I recently returned.

PROS: -With my current setup and PCIE card, I am getting on average 75-90 MBs transfer rates. Currently using eSATA only. My system is older and does not support USB 3.0.
- Its quiet
- Plug and Play
- Great Price!
I recommend for similar intended setup.

CONS: - Short plug in cord length. I want more slack to put in desired location since you do not want to bump/ drop/ ruin/ kill your drives! (has happened to me before.)
- It has a cheap plastic feel! Hard drive pullout handles and tabs cheaper plastic.
- I did not receive all screws to utilize the hard drive handles. 4 drives... 2 sides= 8 screws. Why were only 4 packaged? VERY MINOR inconvenience but a con on purchase nonetheless. Who has spare hard drive screws laying around??

Again, I will be buying this unit again for my next batch of HD. So I do recommend.

I have built my own PC for the last ten years and have never had the problems I encountered with this product. I connected four Western Digital drives, which all work perfectly in my PC tower, to the Vantec box and all seemed well. My PC recognized the drives and proceeded to try to write to the array. No matter whether I used the USB3 or eSata cables the result was always the same. Two minutes after starting to write the drives would switch off. It is important to add the pads to the plastic bays as this improves the drop-out rate of the drives. But I could never get them to last more than a few megabytes of data transfer. Shame on this company for putting such a flakey product on the market and for being so slow in replying to my requests for support. I have requested another to give Vantec the benefit of the doubt but I shall be quick to respond if the replacement is as bad as my initial purchase.
UPDATE
I have discovered from the Vantec support team that the bay is powered by a power supply rated at 5.42A. Each of my drives requires 0.9A for the 5V and 0.75A for the 12V side. All four drives require 6.3A which is too much for the supply. Running with three drives (4.95A) works fine. I await the Vantec solution!

I needed to get some more air space in my server by removing 4 of the 9 drives so it would run cooler. I first bought a Mediasonic HF2-SU3S2 ProBox 4, but it kept disconnecting from the USB 3.0 card. I even upgraded the card to the newest card and latest drivers. I still was getting the same disconnects -- anywhere from every 5 to 15 minutes. I cannot restore from or backup to a device that does that. So I bought this Vantec after reading the reviews. I had it up and running in about 10 minutes with 4 2TB drives installed and it has not disconnected once in about 6 hours of active backup.

A note to the person who says the unit is not shipped with screws. The screws are attached to the back of a cardboard insert in a small plastic bag. Easy to not see these. My guess is that they were put there to keep them from getting lost in the bottom of the box. Ironic really.

At $99.99 I have no problem with the build quality of the Vantec. It is mostly plastic, but seems to be rigid. It is about the quietest device I have with a fan. It is easy to get the drives in and out and is well ventilated.

I've been building systems for 30 years and I am happy with this enclosure.

Update: 29-Jan-2013 ************************************************************

I've been running the 4 drives daily to backup the network. These drives not only get data from the network, but run backups of the backups. So, one drive copies data from itself to another drive in the same enclosure and also to another external USB 3.0 enclosure. All is working perfectly. I have not had one single problem since installing.

Update: 18-Dec-2015 ************************************************************

I've been using this enclosure with the same 4 drives since Jan 2013 and it has not given me one problem.
