5 out of 5 eggsGreat Storage Option

Pros: Easy to set up (see other thoughts), reliable, lots of RAID options.

Cons: Poor documentation, obscure brand.

Other Thoughts: This device has held up well for me for two years. The only support option is email or a rarely used forum, but I was able to get a response quickly within business hours via email and they were able to solve the only problem I had.

The device has a RAID change confirmation button on the back (hidden compartment) and this is not documented well. It must be used to set or change the RAID, which is nice so you don't accidentally break your array, but it isn't obvious how it's used initially.

4 out of 5 eggsShips with Defective USB 3.0 Cable

Pros: Works with good cable with Esata, Firewire and USB 3.0

Cons: Shipped with a defective USB 3.0 cable that causes the device to drop connection. Had to purchase a new cable to make it work.

5 out of 5 eggsRight Tool for the Job

Pros: 1. Hardware RAID built-in
2. Multiple RAID modes, including 5 & 10
3. Support of 6Gbps SATA
4. Excellent price compared to "Enclosure + HW RAID" solutions.
5. Simple controls for setup and operation
6. Wide number of connectivity options

Cons: 1. Power connector on the side, not back
2. Simple controls = Less functionality for some
3. Excellent price = Extensive use of plastic
4. During heavy file copy operations, I have noted some high pitched beeps from time to time.
5. Included paper manual and PDF manual from website offer limit useful, let alone relavent, information (use the CD instead).

Other Thoughts: First, let me say that I had many doubts about this unit and whether it would match the requirements for a home media/file server that I was building. Without a doubt, the unit has met all of my expectations and even exceeded them a bit (let's just say that the manuals in the box and website isn't nearly as good as the one on the included CD).

Second, anyone using a MAC needs to download the MAC-specific firmware upgrade to resolve the issues noted previously.

Third, the unit wasn't ready to use from the get-go when connected to a server as the only storage option. I had to connect it to an existing workstation to initialize the drives and build the RAID5 array before it was usable with my server.

Fourth, despite the claims of some reviewers about no JBOD and a default to RAID0 (and the manual states RAID5 default), all of my drives appeared as JBOD when first attached, so YMMV.

Finally, know the tool you intend to use for a job. This unit has limitations, so it's not a one-size-fits-all RAID enclosure. However, it's an excellent and inexpensive replacement for pseudo-RAID solutions on motherboards and an good-enough alternative to much more expensive RAID cards (I replaced a much more expensive 3ware 9650SE-4LPML). Unless you need RAID 6/50/60, etc, this unit is a very, very good value.

5 out of 5 eggsSet it right up as RAID 5

Pros: Given that you can store incredible amounts of data on this array, your confidence has to be high. So far so well, but I've had other RAID5 arrays that take a day or two to rebuild so I would always suggest having a 'green' drive or two as a backup. Green drives are good for rare access and unsuitable for RAID - mine has Toshiba disks and 170 kB sustained over USB3.

Cons: No JBOD options on this chassis - per design

Other Thoughts: This is not a Just a Bunch Of Disks chassis - if you shove disks in here, they will become a RAID0 spanned array at the lowest size. Don't do that. Put in a bunch of 3TB drives, select RAID5 by holding top button until it flashes, move to RAID5, press button on back (under tab) until array shuts off. When it comes back, you have a RAID5 array for a bargain. Buy another when you realize how cheap it is.

4 out of 5 eggsGreat little box

Pros: - Hardware RAID
- Powers down when computer is off
- USB 3.0
- Almost every RAID config you will need for home use
- Tech support

Cons: - Stopped powering down when computer shuts down after about 1 yr 5 months of ownership

Other Thoughts: When my box wasn't fully functional, tech support was great in providing suggestions and different firmware versions to test on the box. In the end, they worked with me to get the box repaired. Now that it's fixed, its working like new!

4 out of 5 eggsSo Far, So Good

Pros: Despite what I've read, it was very simple and easy to use. I think they have updated their literature since some of these reviews have been written because everything worked the way it was explained in the manual.

I got this with 4 new HDDs and it's been working beautifully since. I took it on a location shoot for a short film and am editing on it now, no issues so far except one...

Cons: The USB 3 drops in and out. I'm okay with that since I use eSATA (this drive is SATA 3 and my drives/mobo are, too, so why not). I am not sure why or what fixes this, but for now it's not much of an issue for me.

Other Thoughts: It seems sturdy and well built. I have it on a lower section of my desk and never have to see the LEDs, so that doesn't bother me, either. It's no brighter than the lights on my case, anyway. Good purchase.

1 out of 5 eggsInaccurate Description

Pros: Steady built

Cons: -Poor design. When you push the door open, it will fall off: it is removable. If your enclosure happens to be on the edge of a desk, it will fall onto the floor.
-It took me a WHILE to insert drives and plug in properly with flash light. The guide rail alignment is not accurate
-External power supply is inconvenient.
-Odd power connector/plug to the enclosure, along with a very thing cable.
-Poor documents. Error light stays on, cannot trouble shoot or get it work.

Other Thoughts: I need a secure external backup for large volume of photograph files. I found this for my SATA III hard drives: they are the only enclosure rated for SATA III hard drives on Newegg website. On the box, it clearly states that it is only for SATA I/II hard drives.

1 out of 5 eggsDon't USE with MAC 10.7 or 10.8

Pros: Awesome unit, if it works.

Cons: Constant disconnect on my Macs running Lion and Mountain Lion. Worthless if it won't stay connected.

5 out of 5 eggs2nd verse same as the first

Pros: Bought one of these last year at $199 and vowed if it came on the shocker I'd buy another. This thing rocks! I stuck 4 3TB hitachis in the first one for 9TB of RAID5 awesomeness! These weren't screaming drives but I get a steady 180+ Mb/s off it and I love the fact that it's not relying on the operating system to keep the RAID intact. In fact, I moved it back and forth between two PCs for the first month as I populated the data.

Cons: The instructions are wrong on how to set up your RAID mode. It clearly says push the button on the back and hold it down until the RAID light flashes. This is blatantly wrong, hold in the mode button on the front until it changes then use it to select the raid mode, THEN press the button on the back until the unit powers down (which confirms the RAID mode). The instructions are rubbish but the enclosure is amazing! Feels heavy like it was well constructed (although the plastic door on the front is a little cheap), but it looks great.

Other Thoughts: The 2nd one I populated with 2 WD green drives (yes, I know they aren't meant for RAID and they wouldn't do it from my onboard RAID controller). The greens are working terrific (surprised me). I think the next thing I'll do (when HDD prices finally drop again) is get 4 more 3TBs and try a mirrored RAID 50 configuration (that should get me wicked speed and double my reliability). Even at $199 this is a great product but at $129 on the shocker... no brainer... I was truly shocked!
