4 out of 5 eggsGreat Raid Enclosure - Ran for 4 years without issue - Recent power issues

Pros: This unit ran without issue for over 4 years straight without being powered down more than a few hours. Rock solid, and great performance. I mounted this unit to a Linux server, and it acted as the main data backbone for my personal network.

Cons: The power board on the unit has failed recently. Currently opening a ticket with Mediasonic support to see what repair / replacement options are.

Other Thoughts: Barring any issues with Mediasonic support to get the unit repaired, I would definitely recommend this unit for the price point. As I mentioned, I had the thing running for over 4 years without issue.

4 out of 5 eggsstill ticking along

Pros: Very easy to set up RAID array and has both eSATA and USB3.0 ports. Still ticking along after more than 2 years of use.

Cons: The front faceplate is poorly designed; it really doesn't stay in place. This is just a cosmetic problem, but an annoying one.

Other Thoughts: There's software online that will monitor the health of your RAID array so you don't have to watch the lights for failed drives.

5 out of 5 eggsExactly what I needed

Pros: Easy to setup, fast. I've had it for a year now with no issues.

Cons: None after 1 year!

Other Thoughts: I have this connected to an i3 BRiX running kodibuntu and get about 100MB/s across my 1Gbps network.

5 out of 5 eggsRuns Like a Top

Pros: The device was purchased at a reasonable cost and the quality is good. The JMicron Hardware RAID Management software is working well also. Setup is easy.

Cons: An internal power supply would be nice but would most likely increase the size of the enclosure.

Other Thoughts: I have been running this enclosure for over a week now with absolutely no problems. I have four Seagate ST4000DM000 4TB drives configured as a RAID 10 array and used as the system backup drive for a Windows 2012R2 server. The ESATA port is being used.

The enclosure is paired with a PCI-E ESATA card, using the ASMEDIA 1061 chipset, in the server.

5 out of 5 eggsAmazing for the price and what it does

Pros: I have only tested in JBOD mode, and from reviews of other products I didn't even know if this would work. But so far it is working properly and doing what it should do (I admit that the drives in this had been through a pws fire... so I was curious to see it the drives would even work in this enclosure... they did). This is a very small enclosure to fit 4 drives. I am very happy with its size and portability.

Cons: From reviews, I don't expect this to last and am only using it as a backup solution that will only be powered up every two weeks of so.

Other Thoughts: So far so good. I am using this in a 4 drive spanning mode to span a 2 - 2 - 2 - 4 gb array of wd green drive of various age.

1 out of 5 eggsmeh

Pros: I liked the fact that it offered esata

Cons: power supply reliability. After less than 30 hours of service components gave out on the inside of the box so that it was not a simple swap out a transformer and power cord. Replaceable but not work I should have to do on a box with so few hours.

Other Thoughts: I would power it up when I needed to copy stuff into long term storage and was generally happy with it until the box electronoics developed issues. It no longer powers up and is probably not worth the time money and effort to fix it right.

Manufacturer Response:

4 out of 5 eggsGreat box but poor software support

Pros: I've been running three of these for over three years without any problems.
One was connected to a Linux server via USB3 and dropped occasionally but it was a USB3 drivers issue not an issue with the box.
They are all now connected via esata to Linux servers, and rock solid with 4x2TB in RAID5 mode.

Cons: Software. Absolutely no Linux support for monitoring the box status.
I'm not sure who is more to blame for this, jMicron or Mediasonic, but it's a pathetic state of affairs.
I don't need or even want a gimmicky skinned front end, I just want to see the status of the box/drives, just give me a command line program to read the status.
If any of these linux machines were desktop machines I'd try installing the jmicron software under Wine, but these are headless servers so all I want is to be able to see the status, and maybe trigger a rebuild (see below).

Other Thoughts: Both times a drive has failed in one of these they've simply disappeared from the Linux server, which I suppose is one way to know a drive has failed.
In both cases I wasn't able to get them start rebuilding to a new drive till I hooked them up (USB) to a Windows laptop running the jMicron software that can be found on Mediasonics forums (make sure you don't allow Windows to initialize the drive since it won't recognize the Linux file system)
Once the rebuild was complete I disconnected from the windows laptop, reconnected the esata cable to the Linux server and was able to remount without a problem...
Not a good scenario if your doing remote support, but sufficient for local systems.

2 out of 5 eggsThe box works fine.... when it has power

Pros: I had no problems with getting it set up and running the way it should be. The actual enclosure it self does exactly what I expected it to do.

Cons: The power cord it uses looks and feels incredibly cheap and I've had 2 fail on me now. Plugged into regular outlets, in open air so it wouldn't get overheated. That seemingly didn't work. I've found other devices that use the same brand, Shanpu Power, power supply with similar failures.

Currently waiting for a response from mediasonic about a third or possible refund on the entire thing to get something else.

5 out of 5 eggssimple

Pros: Compact design and attractive. i was a bit afraid to do this on my own but it was simple to put together and get working. Have not had it for long but so far no problems.

Cons: the power plug being on the side is not the best design. It would be better if it was from the rear. Not really a hinderance just an annoyance if putting flush to a wall on that side.

Other Thoughts: Looking forward to no longer losing data. i got this after having several external hard drives fail....
