Style Name: USB 3.0/eSATA
I purchased this enclosure for my Father. Works very nicely. However as some other's have mentioned the instructions that come with it are pretty confusing (even for someone comfortable with hardware setup). The difficulty we had was getting the drive to switch to the correct mode, in our case RAID 1 for mirroring. We've only had it up and running for a day or so, but it's very fast over USB 3.0. We're going to "burn" it in for a week or so prior to trusting it with anything valuable, but that's just good practice with new drives and hardware - there is nothing so far which leads me to believe that we'll have any issues.

Do yourself a favor, and skip the booklet in the box, and go directly to their website FAQ, which has far more detail. The order of steps is key, and the instructions skip over some steps about the reset and mode changing.

[...]

This is the key set of steps that solved our problem:

I try changing the 400MX storage to RAID 1 mode and it will not work. What am I doing wrong?
Here are the steps:
a) Set the DIP switches to desired RAID 1 mode of operation
b) Connect to power, connect USB to 400MX and PC
c) Go into Disk Management in Windows (Disk Utility in Mac) and power on the 400MX
d) Wait for OS to detect the 400MX and show the two separate drives
e) When the drives appear, press and hold the reset button on the 400MX until both drives disappear (15-20 seconds), and then release the button.
f) A single disk will now appear and will need to be initialized. Initialize, create volume, and then format.

I've been trying to track down a good (fast) RAID0 and RAID1 solution for photo editing on my new Macbook and my MacPro Tower. I bought two of these guys and set one up as RAID0 and one up as RAID1 and plugged them both into the LaCie eSATA Thunderbolt Hub where I'll do editing directly off the RAID0 drive and do backups to the RAID1 drive. I did some benchmarks and was getting ~210MBs read and ~270 MBs write to the RAID0 which is fantastic (108MBs/126MBs read/write in RAID1). This is a great enclosure especially for the price.

Also, this works as a USB 3.0 device on my Macbook Pro!

Style Name: USB 3.0/eSATA, Quad removable Verified Purchase
It seems to work well, but cooling can be an issue. If you crank the 80mm internal fan up high, the middle drives stay hot due to the poor design with no consideration for air flow between drives. The drives face flat to the air, parallel to fan, so the first drive deflects air around 2 and 3. They should be turned perpendicular to the fan, so air can flow through the drives. The fan is also very loud, while still not doing much for drives 2 and 3.

I solved the cooling issue by removing the back plate/drive carriers, and installing a 120mm, USB powered, low noise fan to the back of the case. The case in back is just shy of a 120mm fan width by 2mm, so it's nearly a perfect fit. The drives stay cool, noise is much lower.

I purchased the Vantec HX4R from another online retailer. If I had purchased it from Amazon, I would have been able to return it without problems.

I purchased this enclosure because it gave me the highest capacity for the money. I liked that it had active cooling and many different RAID configurations. USB 3.0 and e-SATA ports allowed me to configure this device with any of my servers. The model I purchased supported SATA III devices up to 4TB each for a total of 16TB storage capacity. All these were/are positive features for the Vantec HX4R enclosure.

There is a reason why this enclosure is so inexpensive. The fan and ports are cheap and flimsy. When I first received unit and populated the drives in it every thing appeared to be good. I installed the software and started transferring files to the drives when configured for RAID 1. The enclosure started to drop connections to the server. I researched this and switched out the USB 3.0 cable for a known good high quality cable with no success. This enclosure kept dropping connection and trying to rebuild the RAID constantly.

The second problem was the cooling fan. When first started up, the cooling fan was silent. Within 3 days the fan sounded like it was grinding the bearings were going bad. It kept getting louder and louder. I played with the fan settings and finally turned the fan off because I was afraid it would cause other damage. I contacted Vantec Tech Support and they knew all about the problem. They gave me a procedure to re-seat the fan blades on the shaft. I thought that was a little weird but it worked - for about 3 more days. I kept re-seating the fan blades to quiet the device and the time between re-seating kept getting shorter and shorter. Finally, I gave up.

Pros: For the price, compared to the Rosewill two-drawer unit I've had for years (which I love but only runs at USB 2.0) and the piece of CR%P Mediasonic I've been putting up with for too long, this thing rocks!

I stared out moving single drives from the Mediasonic I was looking to replace and backing up files to an older WD Black drive I have that's out of warranty. I did all of the copying, erasing and formatting of the original drive, and copying back WITHIN the Vantec as my way of testing it out and putting it under some load.

Never dropped a single connection - never gave up under large transfers ranging from 10gb - 200gb at a time. I would reformat and write zeroes to the old drives, eject the unit, restart the unit, let Windows detect the blank drives, reformat, run WD diag on it, copy about 250gb to the drive, wipe the drives again, format and then copy the original files back to the drive. I was getting anywhere from 80MB to 120MB write speeds to SATA II drives and slightly faster on SATA III drives - I'm happy with that. I was able to do things like run chkdsk on one drive and defrag a second at the same time - something the Mediasonic always balked at and would always stop on.

I've been spending a few hours each day adding and removing drives, wiping drives, doing things like running utilities and creating Truecrypt volumes - things that would just about guarantee my Mediasonic would shut down eventually and stop functioning. This Vantec handles all of that w/o a hitch.

Lights - not as bright and annoying as other units. Tell me just what I want to know.

Design: thought it was a little odd looking, but the bonus with this, and the reasons it's shaped this way, is the giant 80mm fan on top that pulls air up and away.
